| CAS No.: 216597-12-5 Properties: Silane-terminated polymers are important in moisturecuring systems. Systems based on silane-terminated polyethers and polyurethanes are well established alongside the widespread silicone sealants and polyurethane adhesives. Silane-terminated systems have not only advantages of easy processing and high stability of the formulations, but also very good mechanical properties and adhesive strength that can be adjusted within a broad range. The curing of GENIOSIL® STP-E 35 with the release of methanol leads to elastic vulcanizates. Formulations with GENIOSIL® STP-E 35 are characterized by the following advantages: - Simple compounding with conventional auxiliaries.
- Low viscosity in formulations
- High mechanical strenght with very good elastic recovery and high elasticity.
- Rapid curing.
- Broad adhesion profile
Special features: GENIOSIL® STP-E 35 is a silane-terminated polyether with trimethoxysilylpropylcarbamate terminal groups. GENIOSIL® STP-E 35 hydrolyzes in the presence of moisture to form silanols, which can then react with themselves to produce siloxanes. It´s a clear, colorless viscous Oil.Application: GENIOSIL® STP-E 35 is used as a reactive binder for adhesives and sealants, potting compounds and as additive in coatings. Curing takes place in the presence of water or atmospheric humidity. Depending on the formulation, either one-part or two-part systems can be prepared: - Elastic adhesives in structural and automotive engineering.
- Assembly adhesives
- Overpaintable sealant for construction.
- Mold-making and potting compounds.
