In combination with aliphatic polyisocyanates for air- and stove-drying two-component paints for
industrial coating with high flexibility, adhesion and weathering resistance.- Properties and Fields of use
SYNTHALAT A 055 is used primarily in combination with aliphatic polyisocyanates for nonyellowing
coatings for metals and plastics. SYNTHALAT A 055 should be seen as a link
between copolymers of lower and higher hydroxyl content and can therefore also be used as
pigment paste resin.

Technical Details & Test Data
- Film Properties
In combination with aliphatic polyisocyanates like „Desmodur N“, non-yellowing coatings are
obtained that have excellent weathering resistance and gloss retention.
These types of films are characterized by a high flexibility and good adhesion even to problem
substrates.
Because of the very high compatibility SYNTHALAT A 055 is suitable as the combining resin
for A 045, A 065, A 090, A 141 HS and A 150/151.- Pigmentation
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.- 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 055, solid): 42 x 100 x 1.7
17 x NOC %
42 = molekular weight of the NCO group
17 = molekular weight of the OH group
1.7 = hydorxyl content of SYNTHALAT-A 055 in % relativ to non-volatile
content.
Best results are obtained with a mixing ratio of 100 parts by weight of SYNTHALAT-A 055 (from
in which supplied) with approx. 15 parts by weight of „Desmodur N 75%“.
