Ultra-Low Monomer Hybrid Silicate-Isocyanate Resin
Low-viscosity, low free-monomer NCO co-resins for advanced 2K PU systems — high durability with easier compliance.
Why Move Beyond Conventional Isocyanates?
2K polyurethane systems are critical to many adhesives and coatings products. However, formulators face challenges with:
- UV and Weathering Instability – Some resins chalk or yellow after long exposure.
- Chemical and Thermal Resistance – Many degrade under heat or chemical contact.
- Adhesion on Difficult Substrates – Consistent bonding to metals and minerals, including DTM with minimal prep.
- Regulatory Pressure – Tighter monomer limits require safer, compliant options.
- Limited Availability – Few materials offer low viscosity with these combined properties.
Our Solution: XenRes™ I320 & I333
The XenResTM I product family is designed as an innovative co-resin for partial replacement of common isocyanate hardeners and NCO-prepolymers, providing multiple key benefits to formulators.
- Ultra-low monomer content for compliance
- Low viscosity for broad formulation freedom
- UV & weathering resistance
- Strong adhesion to metals/minerals
- Hot-water/cataplasma resilience
- Wide compatibility with standard 2K PU systems
