About
Rheology modifier used in adhesive and sealant applications. It can be used as anti-settling agent for corrosion inhibitors in glycol-based cooling agents. As a non-coupling silane, it can also be used as a slipping agent to simply modify a surface. Suitable as hydrophilic compatibilizer rather than a covalent adhesion promoter. Shelf life: 12 months.
Benefits:
- It is ready to use silane
- Helps to control rheological properties and to reduce viscosity in highly filled polymer systems such as aluminum trihydroxide filled polyesters or SMC pastes
- Features chemical polarity yet remaining chemically not reactive
- Permits workable viscosities at well over 250 phr aluminum trihydroxide loading in unsaturated polyester resins
- Listed under DSL/NDSL, TSCA, IECSC, ENCS, ECL and EINECS/ELINCS
