WorléePol 191
Branched polyester resin, water-thinnable after neutralization, for the production of stoving primers and top coats with excellent mechanicalproperties and very good chemical resistance
Application and Properties
WorléePol 191 is a reactive polyester resin for the manufacture of water thinnable stoving primers and top coats. Primers based on WorléePol 191 have excellent adhesion and very good flexibility. WorléePol 191 in combination with methylated melamine resins is used for the manufacture of non yellowing high gloss stoving enamels with good chemical resistance. For the best can stability the pH- value should be adjusted to 8,0 – 8,5.
wt. amine = (mol. wt. amine) × (acid value of resin solids) × (wt. of resin solids) / 56.100 = 100% neutralization
Recommended Storage and Transport Conditions
Up to 25 °C, avoid direct sunlight.
