In combination with aliphatic polyisocyanates for air- and stove-drying coatings for metals.
These types of two-component coatings are preferable wherever maximum resistance to
chemicals 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 solvents
resistance. They are also distinguished by a very good resistance to water and corrosive
chemicals. Because it has the highest cross-link density, SYNTHALAT-A 192 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 192 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 accelerate drying, organometallic compounds may be added. Good results have obtained
with dilbutyltin dilaurate in a ratio of 0.1-0.5% DBTL - 1% in xylene (solid).- Mixing ratio with poly-isocyanates
Assuming equivalent reaction of the reactive groups (NCO : OH = 1:1), the following formula
applies for the calculation of the amount of polyisocyanate to be added (relative to 100 parts by
weight of SYNTHALAT-A 192, solid):
42 X 100 X 5.7
17 X NCO %
42 = molecular weight of the NCO group
17 = molecular weight of the OH group
5.7 = hydroxyl content of SYNTHALAT-A 192 in % relative to non-volatile
components.
