How long does it take for foam caulk to fully cure?

Foam caulkAlso known as styrofoam and foaming agent, it is a polyurethane adhesive product mainly used to fill gaps and leaks in building doors and windows. It can be seen everywhere in our daily lives. So, how long does it take for foam caulk to fully cure? Let’s take a look with the author.

Under normal circumstances (room temperature20~25℃） PolyurethaneFoam caulkThe surface drying time is about ten minutes.

The full drying time varies with seasonal temperature and humidity. Generally, the full drying time in summer is about 4 to 6hours, and in winter when the temperature is around zero, it takes 24 hours or longer to dry completely.

Under normal use conditions, its service life is not less than ten years, from minus 10℃ to 80 The cured foam maintains good elasticity and adhesion within the range of degrees Celsius. The cured foam has functions such as caulking, bonding, and sealing. In addition, flame-retardant polyurethanefoam caulking agentThe flame retardant level can reach B andClevel.

Extension Information:

When the material is sprayed from the aerosol can, the foamy polyurethane material will rapidly expand and solidify with the air or moisture in the matrix in contact to form foam. Curedfoam caulking agent Foam has many effects such as caulking, bonding, sealing, heat insulation, and sound absorption. It is an environmentally friendly It is an energy-saving and easy-to-use building material that can be used for sealing, sealing, gap filling, fixing and bonding, thermal insulation and sound insulation. It is especially suitable for sealing, sealing and waterproofing between plastic steel or aluminum alloy doors, windows and walls.
