ESSRBOND HY 25 is a moisture-curing sealant commonly used for sealing dynamic structural joints up to 30 mm. After curing, it forms a flexible rubber-type seal that can be painted with ease.

HY 25 has excellent primerless adhesion to building substrates and construction materials. It is a multi-surface sealant that works with aluminium, timber, concrete, and fiberglass. It is recommended for sealing and joint-filling applications and is routinely used for filling gaps in sanitary areas.
