Other characteristics
- Brand
- SYNTHALAT
- Compatible Substrates & Surfaces
- Metal
- Usage
In combination with aliphatic polyisocyanates for air- and stove-drying two-component coatings. These types of 2-component paints should be used preferably wherever maximum resistance to chemicals and weathering are required.
- Carrier
- Solvent-based
- Markets
- Paints & Coatings
- Catalysis
To accelerate drying, organometallic compounds may be added. Good results have been obtained with dibutyltin dilaurate in a ratio of 0.1-0.5% DBTL - 1% in xylene (solid).
- Shelf LIfe
- If properly stored, at least one year.
- Cure
- Chemical Cure
- Supplied As
- 60% in shellsol A/butyl acetate (1:1)
- Pigmentation
SYNTHALAT-A 191 has a high pigment loading and a very good pigment wetting. All neutral pigments and fillers are suitable for pigmentation. Basic pigments containing soluble metallic compounds may exert a catalytic effect on curing and shorten the pot life of finished mixed batches.

- Film Properties
In combination with aliphatic polyisocyantes non-yellowing for coatings with excellent weathering resistance and gloss retention are obtained. These types of coatings have a very high scratch and abrasion resistance combined with a very good solvent resistance. They are also distinguished by a better flexibilty than those with Synthalat-A 190. Because of the maximum cross-link density, SYNTHALAT-A 191 gives paints films that have by far the best resistance to chemicals and abrasion compared with A 045, 065, 085 and A 150/151.

- 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 addad (relative to 100 parts by weight of SYNTHALAT-A 191, solid): 42 X 100 X 5.7 17 X NCO % 42 = molecular weight of the NCO group 17 = molecular weitht of the OH group 5.7 = hydroxyl content of SYNTHALAT-A 191 in % relative to non-volatile components.
