Winter Application Guide for Polyurethane Foam Caulk

<font face=" The normal use temperature of foam caulking agent is 5℃ to 35 ℃,When used in cold winter,especially in environments below -5℃ Construction will affect the normal use and performance of the foam caulking agent. Therefore, when the temperature is low in winter, the most important thing is to make foam The tank temperature of the agent reaches about 15℃-20℃ and according Use the correct construction method to ensure the cleanliness of the foaming agent and the foaming quality. The specific method is as follows:

1. The temperature is low in winter. During use, some foaming agents may be stored for a long time, and the glue produced during glue application will be slightly thinner. This is due to the low temperature. Caused. Therefore, before using the product, please make the following preparations:

1. It should be stored in a greenhouse (around 20℃) for at least one or two hours (preferably 24 hours)

2. The temperature of the tank itself should be guaranteed to be at 10℃ or above, you can use warm water (below 40℃) to iron it, Or hold it with your hands and shake it up and down for 1-2 minutes to ensure that it is The temperature of the tank should not be lower than 10℃, preferably 15℃. However, because the product contains propellant gas, there is a danger of the can exploding after being heated or heated, causing injury to people and property. Therefore, the following methods are strictly prohibited:

(1) It is strictly prohibited to heat or heat with an open flame. (2) It is strictly prohibited to bake or heat (such as electric heaters, electric furnaces, boilers, etc.)

(3) It is strictly prohibited to warm or heat boiling water. (4) It is strictly prohibited to store in an environment with a temperature exceeding 45°C.

2.On the day of construction, you should bring a small amount of foaming agent with you when the temperature is low Bring as much as you need to the construction site, and take it out after use, Do not leave the product in a low temperature environment for a long time.

3. Try to wrap it with thermal insulation cotton when applying glue tank to ensure the tank temperature.

4. When storing in the warehouse, it should be placed in a dry warehouse, not against the wall, and the bottom should be padded with dry wooden boards to avoid moisture, which may cause the tank to rust, and it should not be stored in an environment containing acidic or weakly alkaline substances. The room temperature of the warehouse should be above 0 degrees.

5. Replace with a viscous spray gun (it is recommended to use VAG type C and D spray guns) to make the foam more viscous. Shake the product thoroughly for more than 1 minute before loading the gun to mix the product evenly to avoid unnecessary losses.

5. Please spray a small amount of mist water when using (foam caulking is moisture-absorbing and curing) to speed up curing.

6. When the foaming agent stored in the warehouse for a long time is transported to the construction site for construction, some foaming agents may not be ejected. This is because the foaming agent is composed of different types of chemical raw materials. When stored, due to the different mass ratios of each raw material, it will be in a stratified state in the tank. Therefore, it may not be possible to punch directly at the construction site. You need to shake the tank fully. Make sure the rubber inside the tank is fully mixed before use.

7.Suggestion: To ensure the The performance of the foaming agent is at its best, and construction is not recommended when the temperature is too low. If construction is required, please choose winter-type products.
