What is the nemesis of foam caulk?

Foam caulkWe often use it. It is a good polyurethane foam filling material that can waterproof and seal. So what’s the nemesis of foam caulk? Let’s take a look with the author.

1. What is the nemesis of foam caulking?

Polyurethane foam caulking agent‘s nemesis is water and oil. If there is water and oil, it will not be stable. WhenbubbleWhen sprayed from an aerosol can, foamCaulking agent<font face The material will expand rapidly and react with air or moisture in the matrix in contact to form a foam.

The cured foam has many effects, such as caulking, bonding, sealing, heat insulation, etc.isolatedsound and so on. It is an environmentally friendly, energy-saving and easy-to-use building material. It can be used for sealing and plugging, filling gaps, fixing and bonding, and thermal insulation and sound insulation. It is especially suitable for sealing and plugging between plastic steel or aluminum alloy doors, windows and walls.

Foam caulkThe normal operating temperature of the tank is -5 ;font-size:19px”>~+35℃, the optimal working temperature is +18 ~ span>+25 ℃. In case of low temperature, it is recommended to keep the product at +25 ~+ 30℃Constant temperatureMedium preheat30 minutes to ensure its best performance. The temperature resistance range of cured foam is–35 ~ +80℃.

Foam caulk is a moisture-curing foam that should be sprayed on wet surfaces when used. The higher the humidity, the faster the cure. Uncured foam can be cleaned with cleaning agents, while cured foam should be removed mechanically (grinding or cutting). The cured foam will turn yellow after being exposed to ultraviolet rays. It is recommended to apply other materials on the surface of the cured foam (Cement mortar, paint, etc.). After using the spray gun, please clean it with special cleaning agent immediately.
