Cycat VXK 6364 is a catalyst which is suitable to accelerate the cure of fully alkylated melamine formaldehyde resins. Post curing of films containing Cycat VXK 6364 can occur. Recommended levels of Cycat VXK 6364, calculated on melamine resin (solid), are 1 - 7 %.

Cycat VXK 6364 is usable in solvent and waterborne thermosetting vehicles.

Coil coating

Cycat VXK 6364 is especially suitable for the cure of melamine resins which are used as crosslinkers for polyesters. Recommended level for curing condition: 220 °C, < 50 s (approx. 30 s PMT) is 2.5 - 6.0 % Cycat VXK 6364, based on melamine resin solids.

Can coatings

Cycat VXK 6364 is only suitable for outside application (base- and clear coats). It is not in compliance with FDA 21 CFR175.300 and german recommendation BgVV No. XL.

Clear coats

For acrylic/melamine varnishes (ratio = 70 : 30 to 60 : 40), which are baked at 130 - 150 °C for 15 - 20 min, 3.0 - 4.0 % of catalyst solution based on total resin solid is required.

At temperatures up to 25 °C storage stability packed in original containers amounts to at least 365 days
