SYNTHALAT A 150 S is an acrylic resin cross-linked with polyisocyanate. Used in combination with aliphatic polyisocyanates for air- and stove-drying two-component coatings with high mechanical resistance and high resistance to chemicals and weathering. It has applications in marine coatings, industrial coatings, metal coatings, automotive OEM coatings, and industrial maintenance.

- Catalysis
SYNTHALAT A 150 S is used to accelerate drying, organometallic compounds may be added. Good results have been obtained with dibutyltin dilaurate in a ratio of 0.3-0.5 % DBTL - 1% in xylene (solid).
- Cure
- Chemical Cure
- Supplied As
- 60% in xylene/shellsol A/butyl acetate (2:1:1)
- Pigmentation
SYNTHALAT-A 150 S 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.

- Film Properties
This product is used in Composition 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 resistance to water and corrosive chemicals. Because of its higher cross-link density, SYNTHALAT-A 150 S gives paint films have a significantly higher resistance to abrasion and solvents than those of A 045, 055, 065 and 085. They are only surpassed by those of A 190.
- Properties and Fields of use
SYNTHALAT-A 150 S is used primarily in combination with aliphatic polyisocyanates for airand stove-drying coatings for metals and plastics. These types of 2-component coatings are used preferably in instance where high coating qualities are required but where stoving is impossible due to the size or heat-sensitivity of the object to be coated. Examples are automotive refinishes, prime coatings for busses and streetcars, object made of plastics, etc.

- 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 150 S, solid): 42 X 100 X 4.5 17 X NCO % 42 = molecular weight of the NCO group 17 = molecular weight of the OH group 4.5 = hydroxyl content of SYNTHALAT-A 150 S in % relative to non-volatile components The best results are obtained with a mixing ratio of 100 parts by weight of SYNTHALAT-A 150 S (form in which supplied) to 40 parts by wt. of „Desmodur N 75%. An overcuring or undercuring of up to 20% has little influence on film properties.
