Si-PolyU 4020 is a moderately viscous, low-polar, silane-modified polymer that was developed for the formulation of solvent- and isocyanate-free elastic adhesives and sealants. The polymer backbone is based on polypropylene glycol terminated with trimethoxysilyl groups.
The polymer is moisture curing 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.
Si-PolyU 4020 is suitable for a wide variety of applications and tasks. Si-PolyU 4020 is particularly suitable for use in elastic adhesives with balanced tensile strength and elongation at break and advantageous adhesion properties on various substrates.
The products of Si-PolyU series are similar in terms of product chemistry and application. WhileSi-PolyU 5013 is preferably used in (elastic) adhesives with high tensile strength, Si-PolyU 2550 is mainly used in sealing applications. Due to same chemical basis, all three products can be blended, depending on application.
Si-PolyU 4020 is not covered by ADR/RID regulations.
