WorléeCryl A 2218
WorléeCryl A 2218 is a styrene acrylic resin which can be crosslinked with polyisocyanates


Application and Properties
WorléeCryl A 2218 is preferred for the formulation of very fast drying primers, fillers and top coats for steel and plastics.
In combination with aliphatic polyisocyanates a good adhesion on aluminium, zinced steel and other difficult substrates like PUR- foams is achieved.
Compatibility
- Tolonate HDB* (Vencorex) +
- Desmodur L (Bayer) +
Solubility
- aliphatics –
- aromatics +
- esters +
- ketones +
- glycol ethers, -esters +
- alcohols –
Crosslinking / Catalization
For 100% crosslinking per 100 g WorléeCryl A 2218, 50%
13.2 g Tolonate HDB 75* (Vencorex) is required.
The necessary equivalent quantity of polyisocyanates to be added can be calculated according
to the following formula :
Polyisocyanate quantity = (42 x % OH x 100) / (17 x % NCO)
(42 = molecular weight of NCO-group)
(17 = molecular weight of OH-group)
If the crosslinking should be accelerated it is recommended to add a small amount of organic tin or zinc compounds or tertiary amines (we recommend 1% solution of diethylethanol amine in xylene). The shortened pot life has to be considered.
Pigmentation
WorléeCryl A 2218 is pigmentable with all neutral, water-free pigments and fillers.
Shelf Life
The storage stability of WorléeCryl A 2218 in the originally closed barrel is at a storage temperature from +5 to +25 °C twelve months, counted from the day of the delivery ex works.
*Tolonate is a product of Vencorex. Distribution for Denmark, Finland, Sweden and Norway as well as for Austria, Switzerland and Germany by Worlée-Chemie GmbH.
