How to distinguish the quality of winter-type polyurethane foam sealant

1. Whether it can be normally used when the temperature is lower than 0 degrees.

2. No powder after curing.

3. Good adhesion, not easy to fall off.

4. After curing, the bubble hole should be delicate, without large holes, or it will leak.

5. The contraction should be small, so as not to break the door, crack and leak easily.

6. Large foaming capacity can save costs.

7. Polyurethane foam caulking agents should have elasticity and hardness after curing. Generally, polyurethane foam caulking agents of poor quality have no elasticity and will collapse as long as they are pressed hard

Shanghai shuo DE building materials co., LTD. Specializes in the production of polyurethane foam caulking agent, specializing in creating China's first brand of polyurethane foam caulking agent

Winter type polyurethane foam binder (also known as polyurethane foam sealant or polyurethane sealant, foaming adhesive, foaming agent, etc.) is suitable for the temperature of -10℃ above the use of polyurethane foam sealant is often used in winter, frost resistance, low temperature resistance, good quality. It is the first polyurethane foam sealant used in winter

Winter features:

1. Pre-foaming, one-time foaming rate is 70%, (compared with post-foaming products, pre-foaming products can save 30% overflow cutting cost);

2. High inflation, low comprehensive cost; Can hit 22 meters;

3. Stable foam, high compressive strength, shrinkage and expansion to ensure that doors and Windows do not deform;

4. Suitable for use at temperatures above -10℃;

5. High closed-hole ratio, first selection of waterproof and heat preservation, effectively prevent the second after swelling;

6. Convenient and fast installation, saving labor cost;

7. Strong bonding force makes the door frame bond with the wall extremely firm

8. Insect and mildew resistant.

Application temperature: the normal service temperature of the feeding tank is +5℃ ~ +35℃

Zui low operating temperature -10℃

Zujia operating temperature +18℃ ~ +25℃

Low temperature -35 ℃

Application:

1. Installation of doors and Windows: sealing-and-sealing between doors and Windows and walls, fixing and bonding, bonding of external walls, etc.;

2. Sound insulation and silencing: the gaps in the decoration of language studio and broadcast studio can be filled to play the role of sound insulation and silencing;

3. Daily maintenance: repair of holes, gaps, wall tiles, floor tiles and floors, automobile sound insulation, heat insulation, heat preservation and filling, etc.;

4, waterproof plugging: water pipe, sewer and other holes repair, plugging;

5. Packaging and transportation: it can conveniently package valuable and fragile goods, saving time and speed, and resisting earthquake and pressure.
