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.
