Cross-linking / Catalization
For 100% cross-linking per 100 g WorléeThix A 1420, 50%
15.1 g Tolonate HDB 75
21.5 g Desmodur L 67 (Bayer)
23.6 g Desmodur HL (Bayer)
are required.
The necessary equivalent quantity of polyisocyanates to be added can be calculated according to the following formula:
Polyisocyanate quantity = (42 × %OH × 100) / (17 × %NCO)
(42 = molecular weight of NCO-group)
(17 = molecular weight of OH-group)
The curing of WorléeThix A 1420 can be accelerated by incorporating DBTL, zinc octoate, diethanolamin. The shortened pot life has to be considered.
Pigmentation
WorléeThix A 1420 shows high pigment binding properties and is pigmentable with all neutral, water-free pigments and fillers.
Recommended Storage- and Transport Conditions
Avoid direct sunlight, do not store above 30 °C. At room temperature WorléeThix – hydroxyacrylates in original packing have a shelf life of min. 12 months.
