All of KSRESIN's epoxy resin products are proudly made in the United States with high quality raw materials and thorough quality control testing.

Do you ship internationally?

KSRESIN offers free shipping to the contiguous United States (48 states). Shipping to Alaska, Hawaii, and Puerto Rico are available for an additional cost. We can send some products to Canada, please contact to order.

Does Ultra UV require a UV light to cure?

Ultra UV products contain our advanced UV additives (Hindered Amine Light Stabilizers). These products are two component epoxy resins and do not require a UV light to cure.

My epoxy resin has crystallized, what do i do?

Crystallization is normal and can be easily resolved. Most commonly it is caused by cold temperature exposure or temperature fluctuation. Crystallization typically occurs with low viscosity epoxy resins such as casting and art resins.

If you notice crystallization you can warm the container up in a hot water bath (120° F - 140° F) for around 30 minutes ensuring that the water temperature stays warm throughout the entire 30 minutes. You may have to shake or stir the epoxy resin to help it dissolve. Once the crystallization has dissolved allow the epoxy resin to return to room temperature before use. Be sure to keep the caps tightly sealed and do not allow water to enter the container.

Should I measure by Volume or by Weight?

KSRESIN products should be measured by Volume. We recommend using a graduated mixing container to accurately measure each component. Please check the product page for information regarding the mixing ratio of each product.

What temperature should I cure the epoxy resin in?

For best results we recommend curing our epoxy resin products in an environment of 70-80F. Please note that this includes the ambient room temperature, surface temperature (if applied as a coating), and the product temperature. Colder temperatures can slow or stunt the curing of epoxy resin and warmer temperatures can accelerate the rate of curing.

What is the temperature resistance of ksresin products?

KSRESIN products have a temperature resistance of up to 500° F when accurately measured, thoroughly mixed, and fully cured.

Will epoxy resin work in high humidity conditions?

Humidity and (most) epoxy resins do not work well together. To ensure that your project cures properly we recommend keeping your work space under 50% relative humidity throughout the entire curing process, though some epoxies that we offer may work fine in more humid environments up to 80% RH.

Is KSRESIN low odor?

All KSRESIN products are formulated to be low odor. Please keep in mind that odor effects each person differently, but the majority of our customers notice little-to-no odor.

Does KSRESIN contain VOC?

All KSRESIN products contain less than 5 grams per liter of Volatile Organic Compounds (VOC). This allows our products to be labelled as VOC Free.

What PPE should I use?

Personal Protective Equipment (PPE) is important when working with chemicals, we recommend the below PPE at minimum. Please review Safety Data Sheets of each product before use for additional information and recommendations.

  • Nitrile gloves
  • Eye protection
  • Old clothing, lab coat, apron
  • Air purifying respirator

Is KSRESIN Food Safe or FDA Compliant?

KSRESIN products are FDA Compliant (FDA 21 CFR 175.300) when accurately measured, thoroughly mixed, and fully cured. Please review and follow our instructions closely. We do not recommend using cured epoxy resins with alcohol (e.g. shot glasses, wine glasses), for hot foods, or for use on cutting boards.

Can I use Liquidy Split as a top coat?

Yes, Liquidy Split can be used from the first to last layer (including top coat).

Why is my epoxy resin tacky?

Tackiness is most commonly caused by the mixing ratio, the two components not being mixed homogeneously, or the environment (temperature / humidity) during curing. To ensure the product is able to be cured properly, please ensure you are doing the following:
- Measure a minimum of 60ml at one tim.
- Accurately measure each component by volume at a 1:1 ratio as an incorrect mixing ratio will cause the epoxy resin to have issues with curing.
- Thoroughly mix the two components together until there are no striations/ribbonsand the mixture returns to clear. Scrape the sides and bottom of the container multiple times during mixing to ensure both components are mixed completely. You may want to transfer the epoxy resin mixture to a clean mixing cup and continue mixing for an additional 1-2 minutes.
- Ensure the product temperature, surface temperature, and environment are at least 70F before mixing.
- Keep your environment at a consistent temperature of 70-80F throughout the entire curing process.
- Make sure that your relative humidity level is under 50% as epoxy resin can absorb moisture from the air causing tackiness and other issues.

How do I get rid of microbubbles in my epoxy?

Microbubbles are common when mixing viscous liquids. To minimize microbubbles ensure that you do the following:

- Mix the two components together slowly without introducing air into the mixture.
- The epoxy resin and hardener should be at least 70F before mixing.
- You can warm the epoxy resin and hardener up to 90F before mixing, however this will decrease the working time and pot life of the product.
- Use a heat gun or propane torch to sweep across the surface after applying the epoxy resin.
