Описание материалов:
Pearlstick® 48-60/25 is an elastic, linear, aromatic polyurethane, supplied in form of white spherical granules with a very high crystallization rate and a medium-low thermoplasticity level.
Pearlstick® 48-60/25 is used for the production of adhesives for bonding plasticized PVC to plasticized PVC or other materials such as leather, textiles, rubber, in the shoe industry.
The addition of a polyfunctional isocyanate improves the performance of the adhesive.

SOLUBILITYPearlstick ® 48-60/25 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 ® 48-60/25 gives transparent solutions. It they 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. |
