Technical Details & Test Data

Mixing ratio with polyisocyanate

Assuming equivalent reaction of the reactive groups (NCO:0H = 1:1), the following formula
applies for the calculation of the added amount of polyisocyanate (relative to 100 parts by
weight of SYNTHALAT-A 200, solid):
42 X 100 X 6.0
17 X NCO %
42 = molecular weight of the NCO groups
17 = molecular weight of the OH groups
6.0 = hydroxyl content of SYNTHALAT-A 200 in % relative to non-vol.
components
Best results are obtained with a mixing ratio of 100 parts by wt. of SYNTHALAT-A 200 (form in
which delivered) to 64 parts by weight of Desmodur N 75%. An undercuring or overcuring of up
to 20% has only little influence on film properties.

Pigmentation

All neutral pigments and fillers are suitable for pigmentation. Basic pigments and pigments
containing soluble metallic compounds may have a catalytic effect on curing and shorten the
pot life of finished mixed batches.

Film Properties

SYNTHALAT A 200 is used in combination with aliphatic polyisocyanates like Desmodur N, primer systems are obtained
that give a coating thickness of approx. 15-20 my as wet-in-wet coatings, 25-50 my as primers
or 200-300 my (thick coating) as spray fillers. They are used for instance for automotive
refinishes, prime coats for busses (composite structure), streetcars and airplanes.
