Si-PolyU 2550 is a moderately viscous, low-polar, silane-modified polymer developed for the formulation of solvent- and isocyanate-free sealants and elastic adhesives. The polymer backbone is based on polypropylene glycol terminated with trimethoxysilyl groups.
The polymer is moisture curable at ambient temperature and can therefore be formulated as one or two component systems. Formulations based on this polymer show good adhesion to a large number of substrates, eliminating the need for time-consuming substrate pre-treatment or the use of primers.
