Описание материалов:
Pearlstick® 45-60/08 is an elastic, linear, aromatic polyurethane, supplied in form of white spherical granules with an extremely high crystallisation rate and a low thermoplasticity level.
APPLICATIONS:
Pearlstick® 45-60/03 is used for the production of adhesives for plasticized PVC to plasticized PVC or other materials such as leather, textiles, rubber, etc.
Pearlstick® 45-60/03 enables the production of adhesives with high solids content and low viscosity, which are intended for spray application in the automotive industry and with high performances in the green-strength of the joints and temperature resistance.
The addition of a polyfunctional isocyanate improves the heat-resistance and the strength of the joints.

SOLUBILITY;Pearlstick® 45-60/14 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® 45-60/14 should be dissolved in closed tanks and the use of high shear equipments is advisable. The final viscosity figures can vary, depending on the stirring process and on the solvent/diluents ratios. |
