Описание материалов:
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.
APPLICATIONS: 45-40/19 is used for the production of adhesives for bonding plasticized PVC to plasticized PVC or other materials such as leather, textiles, ect. 45-40/19 has a good temperature resistance, although the addition of a polyfunctional isocyanate improves the heat-resistance still further.

| 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 figures can vary, depending on the stirring process and on the solvent/diluents ratios. |
