Описание материалов:
Pearlstick® 45-80/16 is an elastic, linear, aromatic polyurethane, supplied in form of white spherical granules with a small amount of anti-adherent in the formulation. It has a very low crystallization rate and very low thermoplasticity level. Pearlstick® 45-80/16 is adequate for bonding processes that do not require heat activation (cold bonding).
APPLICATIONS
Pearlstick ® 45-80/16 is used for the production of adhesives for different kinds of materials such as leather, textiles, rubber and a variety of plastics (plasticized PVC, PU elastomers, etc.).
Pearlstick ® 45-80/16 allows the production of adhesives with a very long open-time, which can be used without requiring heat activation.
The addition of Pearlstick® 45-80/16 to other different typesof Pearlstick® increases their open-times.
The addition of a polyfunctional isocyanate to improves the heat-resistance and the strength of the joints.

| SOLUBILITY:Pearlstick® 45-80/16 is soluble in Acetone, Methyl Ethyl Ketone (MEK), Cyclohexanone, Dimethyl Formamide, and Tetrahydrofurane (THF).The solvents and diluents should be water-free (max. 0.1 %), so as to avoid subsequent side reactions during crosslinking with isocyanate. It 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 |
