Uses

In combination with aliphatic polyisocyanates for air drying and stoving metal coatings. These
types of 2-C coatings are preferable wherever maximum resistance to chemicals, abrasion and
weathering are required.

Technical Details & Test Data

Film Properties

In combination with aliphatic polyisocyanates like „Desmodur N“, non-yellowing films are
obtained which have excellent weathering resistance and gloss retention. These types of films
are characterized by high scratch and abrasion resistance combined with a good solvent
resistance. They are also distinguished by good reistance to water and corrosive chemicals.
Because it has the highest cross-link density, SYNTHALAT A 190 gives paint films with by far
the best resistance to abrasion and chemicals compared with A 045, 065, 085 and A 150/151.

Pigmentation

SYNTHALAT A 190 has a high pigment loading and a very good pigment wetting. All neutral
pigments and fillers are suitable for pigmentation. Basic pigments and pigments containing
soluble metallic compounds may exert a catalytic effect on curing and shorten the pot life of
finished mixed batches.

Catalysis

To accelrate drying, organometallic compouds may be added. Good results have been
obtained with dibutyltin dilaurate in a ratio of 0,1-0,5% DBTL - 1% in xylene (solid).
