NOROO HiQ CCH-530 Hardener Slow - 1L

CCH-530 is the slow 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 slow

The TC-5300 TDS points to CCH-530 from roughly 68°F upward, and on larger repairs. Extended open time is what lets the clear level across a full panel in heat instead of skinning at the edges.
