NOROO HiQ CCH-550 Hardener Fast - 1L

CCH-550 is the fast urethane hardener for NOROO's HiQ TC-5300 premium clearcoat. Mixed at 2:1:0.2 with the clear and a DR-421 series reducer.

When to use the fast

The TC-5300 TDS points to CCH-550 in the cold, roughly the 41–59°F range, where a standard hardener would leave the film curing too slowly to handle the part.
