Instructions for using gun foam caulk

Polyurethanefoam caulking agent is also called“Foam glue” , is a kind of material mainly used for filling, sealing and bonding the side seams of doors and windows, component expansion joints and holes. It is a polyurethane elastic sealing foam material that relies on moisture to cure. It is divided into two types: gun type and tube type. The gun type requires a special polyurethane foam gun to use, and the tube type is equipped with a disposable hose. It is a one-component, moisture-curing, multi-purpose polyurethane foam-filled elastic sealing material. The full name of polyurethane foam filler is single-component polyurethane foam filler, commonly known as foaming agent or Foam glue, polyurethane foam adhesive has high viscosity. As a commonly used industrial product, polyurethane foam caulking agent also plays an important role in the construction process.

Foam caulkYou still need to pay attention to the following issues during the construction process:

1.Polyurethane foam caulking agent has a certain after-effect. It does not need to fill all the gaps. It depends on the situation. Generally, half the amount is enough.

2.need to be in When filling a closed space, you should ensure that there is relatively much moisture in the cavity, and the construction needs to be carried out in batches.

3.In use When using polyurethane foam caulking agent, it is best to use it one jar at a time. If you find that there are other materials in the jar after the construction, you can leave the foaming gun in the jar, turn off the flow regulating valve, and place it in a Store in a cool place and use the next day.

4.Under construction If the polyurethane foam caulking agent accidentally splashes on your clothes during the process, you can scrape it off and clean it with detergent; if it splashes on your skin, wipe it dry with a cloth and clean it with soap. .

5.Under construction When workers are carrying out construction, smoking is prohibited, and polyurethane foam caulking agents are not allowed to be near open flames. Empty cans are not allowed to be burned or punctured on the spot, and children are not allowed to play..

Having said so much, how should polyurethane foam caulking be used in construction?

First of all, take a foaming gun and clean it well with detergent to ensure that the hair is The foam gun is unobstructed; then pour the polyurethane foam caulking agent into the tank and shake vigorously to ensure that the polyurethane foam caulking agent and prepolymer in the tank are fully mixed.

Remove the valve protective leather cover on the threaded ring of the polyurethane foam caulking agent, remove the cleaning agent, and fill the polyurethane foam along the threads Install the caulking agent can body onto the interface of the foam gun.

Hold the foaming gun, place the can on top, place the foaming gun under the can, and open the flow regulating valve .

After the construction is completed, remove the material tank and replace it with a special cleaning agent to clean the foaming gun .

The above is how to use the gun-type product. The use of the tube-type product is very simple. There is no need to use a foaming gun. You only need to The tube of the tank belt is disposable, which is very convenient and fast.
