| Pearlstick® 46-10/01 is an elastic, linear, aromatic polyurethane with a very high crystallization rate and a very high thermoplasticity level, available as pellets. Solubility: Pearlstick® 46-10/01 is soluble in methylene chloride, acetone, methyl ethyl ketone (MEK), ethyl acetate and tetrahydrofuran (THF). Diluting solvents such as toluene can be added in large amounts. The solvents and diluents should be water-free (max 0.1%), so as to avoid subsequent side reactions during crosslinking with isocyanates. Solutions: Pearlstick® 46-10/01 should be dissolved in closed tanks, and the use of a variable speed agitator is advised. The final viscosity figures can vary, depending on the stirring process and on the solvent/diluents ratios. Applications: Pearlstick® 46-10/01 is used for the production of adhesives for bonding plasticized PVC to plasticized PVC or other materials such as leather, textiles, metals, paper, etc. Pearlstick® 46-10/01 enables the production of adhesives with high solids content and low viscosity, which are adequate for application in the wood and shoe industries. The addition of a poly-functional isocyanate improves the heat-resistance and the strength of the joints. |
