#2020 will cure completely at room temperature, and does not require additional heat to achieve a full cure. It is intended for parts that will be exposed to lower service temperatures.

High Strength Epoxy Resin with Cure Options


System 2000 Epoxy Resin is a medium viscosity, light amber laminating resin that is designed for fabricating parts and other demanding structural applications. Use this system to maximize the physical properties of carbon fiber, KEVLAR®, and glass laminates! Test results have proven superiority over other room temperature epoxies. Its low viscosity and great handling characteristics make it a favorite in the shop too!

Three high performance hardener systems are available for the System 2000 resin. 20 minute, 60 minute and 120 minute pot life versions are all options. This added variety allows the fabricator to select the system best suited to the size, complexity, or time-frame of the project. Simple parts which need to be demolded quickly should use the 20 minute hardener. Larger and more complex parts can use either of the other hardeners.

Vacuum Bagging applications would typically warrant the longest 2 hour working time. As with any epoxy system, adhere to the proper mix ratios and maintain an adequate curing temperature of at least 70 degrees F. The cure time will be cut in half for every 10 degrees F that the temperature is raised above 70 degrees F. Purchase a single cure, or buy resin in bulk and order a variety of hardeners to keep on hand for any project. 

Chopped strand mat contains a binder which prevents proper bonding with any epoxy resins. Use our polyester or vinyl ester resins with chopped strand mat.

First, select the amount of System 2000 Resin that you will need. Then select your needed curing agent or combination of curing agents. Remember, these are not exact kits, so be sure you have enough Hardener!
