Thin Epoxy Resin

Ground Only

The Thin Epoxy Resin is a low viscosity liquid epoxy resin based on Bisphenol-A. Our Thin Epoxy Resin System is a high quality resin which is popular for lamination with fiberglass, carbon fiber, Kevlar or any type of reinforcement. The syrup-like consistency will generate fast wet-out and easy application of any reinforcement. We recommend choosing your hardener below based on your temperature, curing thickness, desired working time and desired drying times. The Thin Epoxy will produce a low viscosity, semi-clear, low odor epoxy that is not only ideal for layup use, but also as a sealer of porous substrates such as wood because of its penetrating power. You can easily make an adhesive, fairing putty or filler when combining the Thin Epoxy Resin System with a product from our selection of powder fillers.

This resin can be used with our 2:1 hardener, 3:1 Hardener, or 4:1 Hardener depending on the cure time you desire.

This epoxy is NON-blushing.

****************** 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° 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.
