RDR-3350 high temperature laminating tooling resin system, cures at room temperature, but requires post cure to obtain optimal phyical properties. RDR-3350 is extremely tough, excellent handling, has good dimensional stability with excellent heat distortion. RDR-3350 is especially suited for tools requiring elevated temperatures. To reach ultimate physical properties, post cure is necessary. Post cure varies depending on the temperature use of the tool. RDR-3350 maximun temperature is 500° F.

This resin can be custom formulated (in larger qty's) to have a pot life from 5 minutes to 3 days. This resin is a thicker resin compared to most RTM resins, however as it was formulated by a composite resin chemist, it does work amazingly well. This resin will cure at ambient temp but to achieve full high temp stability, the part needs to be post cured.

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. This epoxy is made here in the USA. Hardener is included with this resin.

Upon Completion, the tool should be allowed to cure at ambient temperature for 24 hrs.  Post cure in oven according to the manufacturers schedule for your application.  Post cure schedule ramp up max 50°F every 30 minutes at rate of 2-5°F per minute max. Hold at desired end temperature for 2 hours.
