Description

Hyperseal LM-S Building Alchimica

HYPERSEAL 25LM S is an innovative polyurethane mastic for sealing expansion contraction joints.
It contains polyurethane technology combined with hybrid technology, resulting in a sealing mastic with excellent capabilities.
It polymerizes through a reaction with atmospheric moisture and produces mastic with a low modulus of elasticity (50% joint movement accommodation factor) with excellent adhesion to substrates traditionally difficult for polyurethane, such as glass, aluminum, polycarbonates, etc.
In addition, the material has been modified to have an extrusion identical to that of hybrid and MS sealants.
