In combination with aromatic and aliphatic polyisocyanates for fast drying 2-component
polyurethane coatings, particularly suitable for coating furniture.- Properties and Fields of use
SYNTHALAT-A 1633 is a fast drying polymethacrylate, that permits manufacture of very quick
drying 2-component coating systems. These coatings are suitable for industrial furniture
coatings and other wood coatings.
The good compatibility with „Desmodur“ types HL and IL makes it possible to achieve a rapid
stackability even without physical drying additives such as nitrocellulose.
The use of Cellit and NC with „Desmodur N and L“ also permits fast drying coatings with long
pot lives.

Technical Details & Test Data
- Mixing ratio with poly-isocyanates
Assuming equivalent reaction of the reactive groups (NCO : OH = 1:1), the following formula
applies for calculation of the amount of polyisocyanate to be added (relative to 100 parts by
weight of SYNTHALAT-A 1633, solid):
42 X 100 X 2,0
17 X NCO %
42 = molecular weight of the NCO group
17 = molecular weight of the OH group
