Category: Surface Coats
Hardeners: 302 & HT-106-3
Description: HSC-902 s a special surface coat yielding high gloss and abrasion resistance, along with resistance to extremely high temperatures. This high heat resin system is the recommended surface coat for use with high temperature laminating. HSC-902 cures at room temperature and can be used without post cure for temperatures up to 275°F. Post curing is recommended when tools will be used from 275°F to 350°F. If tool is to be used at 350°F, post cure at 375°F. After final post cure temp., shut off oven, remove tool when oven reaches ambient temperature.
