Material Notes:
Pearlstick 49-46/03 is an elastic, linear, aromatic polyurethane with a very high crystallization rate and a low thermoplasticity level, available as pellets.Solubility: Pearlstick 49-46/03 is soluble in acetone, methyl ethyl ketone (MEK), cyclohexanone, dimethyl formamide and tetrahydrofuran (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 isocyanates.Solutions: Pearlstick 49-46/03 gives transparent solutions. It should be dissolved in closed tanks, and the use of high shear equipment is advised. The final viscosity fies can vary, depending on the stirring process and on the solvent/diluents ratios.Applications: Pearlstick 49-46/03 is used for the production of adhesives for bonding plasticized PVC to plasticized PVC or other materials such as leather, textiles, rubber, etc.Pearlstick 49-46/03 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 poly-functional isocyanate improves the heat-resistance and the strength of the joints.
