foam caulk Features and how to use them

Foam caulk It is a new type of environmentally friendly and energy-saving decoration material. I think everyone does not know much about this material. So, what is foam caulking agent? What are the characteristics of foam caulking agent? belowAuthorI will introduce it to you to help you understand better.

What is foam caulk?

Polyurethane foam caulking is a one-component, moisture-curing, multi-purpose polyurethane foam-filled elastic sealing material. Polyurethane foam caulking agent is a special polyurethane product that fills polyurethane prepolymer, foaming agent, catalyst and other components into a pressure-resistant aerosol can. During construction, the aerosol colloid is sprayed to the site to be constructed through a matching glue gun or manual nozzle, and the molding, foaming, bonding and sealing processes are completed in a short period of time. Its cured foam elastomer has the properties of bonding, waterproofing, resistance to thermal expansion and contraction, heat insulation, sound insulation and even flame retardancy（Limited flame retardant type) and other excellent properties, it is widely used for filling and sealing the edge seams of building doors and windows, component expansion joints and holes.

Features of foam caulking:

1, foam caulking agent has ultra-low temperature thermal conductivity, weather resistance and heat preservation.

2, foam caulking agent is shockproof and resistant It will not crack, corrode or fall off after curing.

3, foam caulking agent for efficient insulation , sound insulation, waterproof and moisture-proof after curing.

4, foam caulking agent is efficient and energy-saving , no gaps after filling, strong bonding after curing.

5, foam caulking can stick Attach to concrete, coatings, walls, wood and plastic surfaces.

How to use foam caulk:

1, take a polyurethane foam gun and clean it with polyurethane cleaning agent to ensure smooth flow.

2, take another bottle of foaming To remove the agent, hold the middle of the can body firmly with your hands and shake it forcefully in the transverse direction of the can body for at least 20 The internal prepolymer is thoroughly mixed.

3, remove the foaming agent thread ring Put on the protective leather cover of the valve, remove the cleaning agent from the foaming gun, and install the foaming agent tank onto the interface of the foaming gun along the threads.

4, hold the foam gun handle tightly , ensure that the material tank is placed above and the foaming gun is below the material tank, and open the flow regulating valve at the rear of the foaming gun.

5, the gun head is aimed at the objectThe bottom or inside of the part to be filled, gently pull the trigger to start construction. The appropriate flow rate can be adjusted through the flow adjustment valve behind the foaming gun.

6. After spraying one can, If you still need to fill it, you can immediately remove the empty can and refill the foaming agent according to point 3 and continue. construction.

7. After the construction is completed, pick up the Unload the tank and replace it with a special cleaning agent to clean the foaming gun to prevent residual material from solidifying and clogging the foaming gun.
