  • Reviews

Our Thick Epoxy Resin is a high quality resin system which works well for bonding, gluing and coating applications. This resin allows for high build rates. This resin should NOT be used for lamination of Fiberglass, Carbon Fiber or Kevlar because it will not wet-out the materials correctly.  Resin viscosity: 12,500 cps.

This resin uses a 4:1 hardener. Mixing 4 parts epoxy to 1 part hardener will give you the appropriate final mixture.

The 4:1 hardener has a pot life of 15 minutes at 80° F, set time of 1-2 hours and a drying time of 3-4 hours.

This is considered to be a fast hardener, Our 2:1 and 3:1 hardener epoxies will cure much slower. However this 4:1 hardener will provide you with the most rigid laminate due to its extremely fast curing time.

The item has a shelf life of approximately one year. To ensure quality results and proper curing, please make sure to use the resin shortly after purchase.

****************** Cold Weather Warning ***************

If your epoxy arrives cold during shipment is must be allowed to acclimate to at least 75° F before using. Mixing this product below 75°F will increase the potential for under-mixed epoxy which will create wet or sticky areas on your surface. Cold temperatures will also trap more very tiny air bubbles during the mixing which cannot always be removed with the torch/heat gun. In addition applying the mixed epoxy in temps below 70 degrees F will drastically extend cure times. To warm the epoxy quickly we recommend using either a heat lamp, an electric heater or placing the closed bottles of epoxy in a tub of warm water for 30 minutes. Getting the epoxy too hot will result in a faster reaction time, so pay careful attention to what you're doing.
