Sealant HYPERSEAL®- EXPERT-150

HYPERSEAL®-EXPERT-150 – Polyurethane hybrid sealant of a new generation for sealing and sealing joints. One-component paste-like material based on polyurethane. It polymerizes under the influence of air humidity.
   Low modulus sealant with Shore A25 hardness. Non-toxic after polymerization. Resistant to ultraviolet radiation.
   Due to its special hybrid composition, it has excellent adhesion on surfaces traditionally problematic for polyurethane sealants, for example, glass, aluminum, steel, polycarbonate, etc.
   The sealant is easy to apply even at low temperatures. HYPERSEAL®-EXPERT-150
Application conditions
type of foundation
Concrete, polymer cement mixtures, metal, glass, wood, etc.
Base strength
R28 = 25 MPa (minimum 15 MPa)
Base moisture
W <10%
Air humidity
W <85%
Operating Temperature (Tvozd, Tosn)
5 ° C – 35 ° C, 3 ° C above the dew point ** It is allowed to apply sealant at low temperatures (up to -15 ° C). The necessary conditions for this are: holding the sealant before starting work in a warm room (for convenience of work) and a dry surface (no frost). The polymerization time increases.
