Polyester-based polyurethane adhesives show a large range of performance responding to the expectations of many market segments like footwear, construction, woodworking, transportation, electronics, assembly operations or packaging.
In the most demanding conditions, polyester-based polyurethane adhesives must endure high heat, aggressive media like chemicals or moisture.

Hycasyl is a new family of Hydrolytic Stabilizer developed for medium to high performance 2-component solvent-based polyester polyurethane adhesives.

The increase observed with Hycasyl additives in both heat and hydrolysis resistance will enable to extend the performance range of medium-performance adhesives. At the same time, high performance adhesives will show a significant extension of time to failure.

Therefore the use of Hycasyl will enable you to either use more cost-effective backbone materials or push medium and high performance products into new market segments based of their expanded properties
