Best Epoxy Resin for Thick Pours Comparison Table

Education: How to Choose the Best Deep Pour Epoxy Resin

Epoxy resins are used for different purposes. When buying epoxy resins, it’s critical to understand the material and compatibility of your epoxy project. 

When buying epoxy resin, consider mix ratio, viscosity, hardness, and curing time to help you pick the best resin for wood.

Here are other factors to consider when buying the best epoxy resin. 

1. Bubbling 

Even skilled craftspeople can experience bubbling from time to time. These obnoxious air pockets can wreck the appearance of your cured epoxy surface.

Select a formula that enables bubbles to float to the surface. Be keen to work only in a temperature and humidity-controlled environment.

If everything else fails, use a heat gun or torch to remove bubbles from the surface of your cured epoxy resin coating. 

If you pick the best epoxy resin, you won’t struggle with bubbles that much. To avoid frustrations by the bubbles, use a slow-cure epoxy resin. Slow-cure epoxy resins allow bubbles to escape because they take longer to cure.

2. Durability

You want your deep-pour resin to last long before showing any deterioration. The key specifications you should consider when buying epoxy resin to ensure durability are:

3. Scratching $ Abrasion 

Hard-wearing surfaces should be able to withstand the majority of abrasions. Although we would never recommend using an epoxy resin-coated surface as a cutting board, we searched for pourable resins that can work with items without leaving visible incisions.

4. UV Damage

Unfortunately, the majority of epoxy resins are incredibly vulnerable to UV damage. Non-yellowing formulas are ideal for long-lasting outdoor table coating.

In addition to your preferred finish, consider purchasing a UV-resistant topcoat. Even UV-blocking epoxy resins are prone to damage after continuous exposure to UV rays.

5. Water

Coating epoxy resin is a conventional finish used on outdoor wooden surfaces, bars, and tabletops. These surfaces are exposed to water and humidity damage.

An utterly waterproof coating helps to keep them free of ugly watermarks and prolongs their lifespan. 

6. Mixing Ratio 

Epoxy resin is composed of two components: a resin and a hardener. When the resin and hardeners are mixed, they undergo a chemical reaction that converts them from a liquid to a solid.

Measuring accurately is critical to ensure that your epoxy resin for thick cures properly. Always follow the manufacturer’s instructions to get professional results.

Know that high-viscosity epoxy resin is more likely to produce bubbles than low-viscosity epoxy resin. Although your specific project will determine this, choose a low-viscosity epoxy resin if you have the option of viscosity.

7. Food Safe and Application Method 

Most epoxy resins are used on surfaces that indirectly contact food. To coat a tabletop,  ensure your resin meets all FDA requirements. Check to see if the formula is non-toxic and free of harmful VOCs.

Even so, non-toxic formulations should only be used in well-ventilated areas. A safety mask, glasses, and gloves may be necessary.

8. Self-leveling

The use of self-leveling epoxy makes your job such a breeze. This epoxy type can fill voids, seal cracks, inlays, and deformations on the wood surface.

You won’t worry about streaks or other surface flaws because there’s no requirement for a paintbrush or roller.

Cleaning self-leveling epoxy with soap and water is all you need unless compliance regulations mandate buffing and polishing.

Since the surface is one seamless sheet, it inhibits microbial life, such as mold and mildew, by providing them with no place to live. An epoxy containing powerful antibacterial agents is a superb option if you require a cleanroom setup.

9. Working and Curing Times

Cure time specifies how long you should wait before removing clamps, sanding, or proceeding to the next step in your epoxy project.

The hardener cure speed and epoxy temperature determine each mixture’s available and general cure times.

Each hardener has a unique temperature cure range ideal for it. Each resin/hardener combination passes through similar cure stages at different rates, at any temperature above minimum-use temperature.

Choose a hardener that will give you enough working time for your project at the temperature and conditions you’ll be working in.

Extended curing times mean more time to work on your project, allow bubbles to escape, and won’t ruin your project. Quick curing time means you have to work fast.

10. Application And How Much Resin You Need

Carefully think about the method you will use to apply the resin and determine what quantity is necessary for your undertaking.

Depending on the epoxy, one may need to brush or roll it onto a surface for proper application. Meanwhile, others allow you to pour them directly.

Tips for Using Epoxy Resin

Have a work plan. Before you begin, consider the whole procedure.

1. Ensure that your substrate is ready. Only start blending your epoxy resin after keenly reading the instructions and having all of the necessary tools in front of you.
2. If you are trying a new mix, prepare a few sample mixes to determine the curing time. This also helps you understand the properties of the compound. After thoroughly mixing your product, you can apply it to your substrate.
3. Sand the surface with 150-grit sandpaper on high gloss areas for maximum adhesion. After all, you do not want any dust or other particles on your cured epoxy surface.
4. Use a new brush and clean it with your site’s sticky side before mixing the epoxy. This helps to lose fibers that could ruin your final product’s appearance. Use a chip brush, bristle brush, or a nap roller for pro results. 
5. Store Your epoxy in a room-temperature place. That’s so because Heat speeds up the curing process, while cold temperatures can interfere with epoxy adhesion.
6. For epoxies with a quick cure time, allow the epoxy resin to sit for a few minutes before pouring it. Keep in mind that high temperatures can shorten curing times. If the warm temperature is challenging, place ice packs in a zip-lock bag to cool the bucket or bottle you’re mixing in. You can also use a slow-down procedure by adding paint thinner, extending pot life.

Deep Pour Resin Vs. Tabletop Resin

Deep pour and tabletop resin are two types of epoxies that differ in their properties and applications. Deep pour resin is designed for thicker applications, up to 2-4 inches per layer.

Working with deep pour resin requires more patience as the curing process may take 24 to 48 hours. With its low viscosity, Deep pour can be effortlessly poured and simultaneously remove any air bubbles.

Crafting stunning river tables, intricate, deep resin molds, and other epoxy projects that require a large amount of poured resin? The deep pour is the answer!

This type of resin offers an easy solution to these otherwise complex projects. On the contrary, the tabletop resin is ideal for projects that require a delicate and consistent coating, such as river tables, countertops, and bar tops.

This resin stands out with a quick cure of 24 hours or less and a higher viscosity than its competitors. Its superior thickness prevents it from running over the edges, so you can rest assured that your project will stay in place without any mess!

Other Resin Types

Coating Resin

This solution is both stylish and useful. It gives you a smooth finish that helps protect your belongings and keep them hidden.

Applying epoxy resin can protect the item you cover with it, helping to prevent scratches and other forms of damage. You can make your concrete floors look shiny and special by coating them.

UV Resin

This material only needs one part, and using a special UV light will become hard. When the light shines on this material, it will dry quickly.

This gives you time to work with it. But be careful! It only lasts six months, so you must use it immediately.

Alkyl Resins

Polyhydric alcohols and polybasic acids are needed to make these materials.

These materials stay cool and help electricity travel quickly. So they are great for insulating things, making electronics, and making paint.

Acrylic Resins

These items are made with strong acrylic acid. They are very tough and can protect against the sun’s rays.

Silicone Resins

These materials keep water away and stay the same even when it gets hot or cold. People use them to make things that don’t let water in, like laminations, rubber, coatings, paints, etc.

Polycarbonate Resins

With a high refractive index, these materials come in handy when manufacturing various items, such as lenses and helmets. They are also incredibly useful for creating photographic films with quality results.

Polyester Resin

These materials can be changed easily and are very good in hot temperatures. They are not expensive and can be used for lots of things. You can use them to laminate, build stuff, make fishing rods, decorations, coatings, or even bottles!

Polyurethane Resin

Polyurethane resin technology safeguards electronics and is a popular feature in automobiles. It can withstand extreme temperatures. When you heat it, the material becomes incredibly resilient and durable.

This material is great for mold making because it sets fast, sticks well, and moves easily.

Interesting read: Difference between epoxy and polyurethane.

Epoxy Resin Vs. Casting Resin

One should never mistake “casting epoxy” and “epoxy resin” as they are not interchangeable terms. They serve different purposes and thus have distinct definitions.

Epoxy resin is a strong adhesive, coating, and sealant for surfaces while casting. Epoxy has been specifically designed with low-viscosity properties to accommodate deep pours – making it perfect for crafting river jewelry or tables and encapsulating items in molds.

FAQs

Why is Epoxy Resin the best for thick pours?

Epoxy resin is ideal for thick pours due to the following reasons.

• It has a simple 1: 1 mix ratio by volume, so anyone can mix and use it hassle-free.
• It’s self-leveling. So you do not need to buy expensive brushes or rollers.
• It’s odor-free. It won’t produce any upsetting smell when using it.

• It also has a sufficient cure time of two to three days, so you do not have to wait an eternity to complete your project. 

How thick can you pour Epoxy Resin?

When using epoxy resins, knowing when the two parts of resin (Part A) and hardener (Part B) are combined is critical. A chemical reaction occurs that generates Heat during the curing process. As a result, regardless of the epoxy you use, it is crucial to control the temperature and keenly follow the instructions on the label.

If your epoxy pour is thick, the reaction can generate too much heat, resulting in a product with unsightly cracks or excessive bubbles that won’t cure properly. If you leave a thumbprint with your fingernail in it, you can pour fresh epoxy over the epoxy, which will chemically bond to the preceding layer.

Regarding the maximum thickness of epoxy resin, you can go as thick as you want if you pour in 1/8″ layers. We highly recommend this thickness for two reasons: first, it enables the bubbles to escape ideally, and second, it prevents the resin from overheating.

Pour in a 1/8″ layer for optimal results. Remember that the 72-hour cure time is for resin art, so it’ll take longer to cure if you pour it a bit thick fully.

What epoxy is best for deep pours?

Casting epoxy resin is the best resin for thick pours. Because it will be thicker, only one or two pours will suffice. So you may not need multiple layers to be happy with the results. It is Heat resistant. As a result, there will be no issues while curing it. It is also clear and lovely. It’s simple to use and doesn’t change its structure once you’ve created something with it.

What is the best resin for deep casting?

Epoxy resin is the best resin for deep casting. The resin can be poured in thick layers (up to two inches based on the formula), and it cures hard and is very stable. Epoxy cures crystal clear, but you can tint it with resin dyes to create the color of your dreams.

Is epoxy resin safe to use indoors?

Although epoxy resin products are safe,  fumes can be inhaled while mixing and prepping them for application, causing inflammation and irritation in the nose and throat. Use epoxy resin outside or in well-ventilated areas while wearing gloves, safety glasses, and masks.

What is an epoxy resin used for?

One of the most common applications of epoxy resin is as an adhesive. This is due to the epoxy’s solid properties, which allow for systemic and engineering adhesives. Epoxy resin is usually used in the vehicle construction and manufacture of snowboards, aircraft, and bicycles.

Deep Pour Resin Summary
