Material Notes:
Pearlstick 45-40/19 is an elastic, linear, aromatic polyurethane, supplied in form of white spherical granules with a very high crystallization rate and a medium thermoplasticity level.Solubility: Pearlstick 45-40/19 is soluble in Acetone, Methyl Ethyl Ketone (MEK), Cyclohexanone, Dimethyl formamide, (DMF), 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 isocyanate. Pearlstick 45-40/19 should be dissolved in closed tanks and the use of a variable speed agitator is advisable. The final viscosity fies can vary, depending on the stirring process and on the solvent/diluents ratios. Applications:Pearlstick 45-40/19 is used for the production of adhesives for bonding plasticized PVC to plasticized PVC or other materials such as leather, textiles, etc. Pearlstick 45-40/19 has good resistance to temperature, although the addition of a polyfunctional isocyanate improves the heat-resistance still further.Information provided by Merquinsa
