It is characterized by high adhesion to the surfaces of foam concrete and concrete, as well as masonry, PVC, galvanized surfaces, wooden boards and tin sheets. In addition, it does not deform with sudden temperature changes and does not require additional preparations before use.
Intended for use for the following applications:
- Inter-panel seams — in industrial and civil construction.
- Sealing of any connections on the roof — pipes, roortop, parapets, drainage.
- Structural glazing, greenhouses and winter gardens.
- Automotive production — sealing of seams in refrigerators and vans.
- Wooden house construction — junctions between round logs.
- Installation of windows — to protect the mounting foam from ultraviolet radiation.
- Shipbuilding — connection of structures.
Resistant to environmental influences and ultraviolet radiation. The sealant for joints and concrete has a high adhesion to many surfaces (wood, brick, concrete, plaster) and provides reliable sealing of cracks, joints and air ducts both outdoors and indoors.
DESCRIPTION OF INVAMAT PU25 SEALANT
It is characterized by high adhesion to the surfaces of foam concrete and concrete, as well as masonry, PVC, galvanized surfaces, wooden boards and tin sheets. In addition, it does not deform with sudden temperature changes and does not require additional preparations before use.
APPLICATION OF INVAMAT PU25 SEALANT
Used in the construction and repair of buildings and structures. Apply directly sealing inter-panel joints and cracks, including in places subject to subsequent deformation.
STORAGE AND TRANSPORTATION
Warranty shelf life 12 months at from 50С до 300С in intact factory package. The sealant can be transported at low temperatures up to -120 °C.
Precautions
Avoid contact with unprotected skin areas, eyes. Do not ingest. Not explosive, in the non-vulcanized state, can be washed with hot water and soap. In the cured state, can be removed mechanically.
