The R3501 Epoxy and H5000 Hardener Vacuum Infusion Epoxy Kit is a very high quality, low viscosity resin system which works perfect for the vacuum infusion process. You must use a special resin for vacuum infusion. If you try infusing the wrong type of resin you will not get the proper saturation in your laminate and you will have many air voids which cause weak spots. Also a thicker resin will not flow properly and will not flow entirely across your part. This resin was designed for use in our own production process of composite parts but due to customer request we added this product on our site for purchase. We work with a resin chemist that creates epoxies for use in OEM Ford production parts so you are getting epoxy of high caliber at a reasonable price. This epoxy is made here in the USA. Hardener is included with this resin.

To ensure quality results and proper curing, please make sure to use the resin shortly after purchase. This resin is also available in 5-Gal Pails, Drums and Totes.

Epoxy resin and hardener formulations have a long shelf life compared to many polymers but components may settle during storage. We recommend a visual inspection and to stir the resin as needed.

Store Epoxy resins and hardeners at room temperature (65°F- 85°F) in sealed containers until shortly before use. As with many high-performance epoxy resins, repeated exposure to low temperatures during storage (<55°F) may cause the resin to crystallize. Be aware that containers placed near outside walls or on the floor will often be at a lower temperature than the ambient conditions.

If crystallization occurs, warm the resin to 125°F for 8 hours and stir to dissolve crystals. Hardeners may form carbamation when exposed to CO2 and moisture in the atmosphere for extended periods of time. Prevent carbamation by keeping containers sealed and pump reservoirs covered until immediately prior to processing.
