Roberlo KX45 UHS Hardener Standard

KX45 is the standard-speed hardener in Roberlo's KX line, the series shared across the Kronox clearcoat range. This is the default catalyst for normal booth conditions and the one most shops go through fastest.

When to use the standard

Temperature-controlled booths and ordinary working conditions. If the shop is running hot, or the panel is large enough that the first pass has started to set before you reach the far end, switch to KX44 slow instead.

Technical data

Works with

• Kronox 620 Clearcoat UHS 2:1
• Kronox 510 Clearcoat UHS 2:1

Roberlo also lists KX43 extra slow, KX44 slow and KX46 fast in this line. We stock KX44 alongside this one and can source the other two on request.

Handling

Close the container immediately after use. Hardener is moisture sensitive: an open can and a humid shop will cost you the product. Application equipment must be completely dry.
