Technical DataSheet | Supplied by Lubrizol

Discontinued : product no longer available

Pearlstick™ 45-50/03 by Lubrizol is an elastic, linear, aromatic polyurethane. Exhibits extremely high crystallization rate and a medium-low thermo-plasticity level. Possesses good heat resistance, hydrolysis resistance and improved freeze resistance. The addition of a poly-functional isocyanate improves the heat-resistance and the strength of the bonding. It is soluble in acetone, methyl ethyl ketone (MEK), cyclohexanone, dimethyl formamide, tetrahydrofurane (THF). Diluting solvents such as toluene and ethyl acetate can be added. The solvents and diluents should be water-free (max. 0.1 %), so as to avoid subsequent side reactions during crosslinking with isocyanates. Pearlstick™ 45-50/03 is used in the production of adhesives for spray application for the automotive and other industrial uses.
