Cross-linking / Catalysing
For 100% transfer for 100 g WorléeCryl A 2445 is needed:

40.9 g Tolonate HDB*
29.2 g Tolonate HDT LV*
48.3 g Desmodur L 75
The necessary equivalent quantity of polyisocyanates 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)

The hardening of WorléeCryl A 2445 can be accelerated by addition of DBTL, zinc octoate and diethanol amine. Please note the shorter pot life.

Pigmentation
WorléeCryl A 2445 is pigmentable with all neutral non aqueous pigments and fillers.

Shelf Life
The storage stability of WorléeCryl A 2445 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.
