Hybrid Sealants & Adhesives

Hybrid Sealants & Adhesives

With hybrid sealants and adhesives Den Braven 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 provides 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.

In the current days 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 also these high performance products do also have their limitations and disadvantages. The hybrid sealants of Den Braven are actually the “Newest High Performance Products”. Den Braven was able to develop the current portfolio of hybrids and kept keep the advantages and eliminate the disadvantages of the “older high performance” products.

Den Braven ‘s new generation high performance sealants are hybrid based. Hybrids polymers do have a 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 provides better adhesion, abrasion resistance and low temperature extrudablilitye than silicone sealants. Den Braven ‘s new generation high performance sealants are also isocyanate and solvent-free. systems.
