Si-PolyU 4020

Si-PolyU 4020 by PolyU is a highly efficient, allergens- & nanomaterials-free, moderately viscous, low polar, silane-modified polymer which has a polypropylene oxide-backbone, terminated with trimethoxysilyl groups.

• It exhibits moisture-curing properties at ambient temperature and can be formulated as one or two-component systems.
• It possesses a good tensile strength of formulation combined with good elongation at break and broad adhesion spectrum even without primer.
• It also acts as a reactive binder for casting compounds and it reacts upon exposure to moisture.
• Si-PolyU 4020 is suitable for the formulation of solvent- and isocyanate-free elastic adhesives and sealants.
• It has a shelf life of 12 months.
