Use and store between 65° - 80°F (product and ambient temperatures), 45°F minimum. Use below 45°F requires special hardener selection, consult with Rhino sales personnel for recommendation. Remove surface contaminates such as water, dirt, rust, and petroleum products. Wax or “release” mold surface before epoxy application. All Rhino hardeners are compatible with Rhino 1303 so proportion resin in accordance with the selected Rhino hardener. Use of Rhino 1303 resin in RTM or filament winding processes require specialized hardener(s) and equipment. Mix resin and hardener for 3 – 5 minutes being certain to scrape mixing container bottom and sides. Mix no more material than can be applied before pot life expiration.


Rhino 1303 cures overnight at typical ambient temperatures (50° - 90°F) with full properties developing in 7 days, see hardener data for specific cure schedules and properties.
