Addocat® 1221 VN

Addocat®1221 VN is a blend of tertiary amines with polyetherpolyol. Acts as a catalyst for the manufacture of rigid polyurethane foams and building boards. It is hygroscopic and should therefore be protected from humidity. It should be stored in closed containers at temperatures of about 20°C. It turns yellow to brown on exposure to air and light, but without losing its catalytic effect. It allows a good start time and good cure. For PUR rigid foam the dosage is approx. 2.0 - 4.0 p.b.w. It has a shelf life of 6 months.
