Hybrid Sealants & Adhesives
With hybrid sealants and adhesives the Den Braven Group is focussing on silylated urethane and silylated polyether based products. Where silylated urethane based hybrids have been developed to extend the property range of the conventional polyurethane sealant.
Silylated polyether based hybrids provide low viscosity, low glass transition temperature, flexibility over a wide temperature range and low odour. In general hybrids are free of isocyanates, solvents and silicones.
These days, polyurethane and silicone sealants are seen as the “high performance products”. They deliver a significant adhesion, a good movement capability and are durable. However, these high performance products do also have their limitations and disadvantages. The hybrid sealants of the Den Braven Group are actually the “Newest High Performance Products”. The Den Braven Group was able to develop the current portfolio of hybrids and keep the advantages and eliminate the disadvantages of the “older high performance” products.
The Den Braven Group’s new generation high performance sealants are hybrid based. Hybrid polymers do have better weathering characteristics than conventional polyurethane sealants, but without the odour and paintability problems of conventional silicone sealants. Den Braven ‘s new generation high performance sealants provide better adhesion, abrasion resistance and low temperature extrudability than silicone sealants. Den Braven ‘s new generation high performance sealants are also isocyanate and solvent-free systems.
