Why does waterproof putty need to add HPMC hydroxypropyl methylcellulose?

What are the advantages of using hydroxypropyl methylcellulose (hpmc) for waterproof putty? Why does HPMC need to be added to waterproof putty?

Answer from China's Leading HPMC Supplier There are several important reasons for using hydroxypropyl methylcellulose (HPMC) in waterproof putty:

1. Thickener and binder: HPMC (hydroxypropyl methylcellulose) is a soluble polymer with excellent thickening and binding properties. In waterproof putty, HPMC can effectively increase the viscosity and viscosity of the putty, making it easier to apply on the wall, and can maintain the uniformity of the putty and avoid cracking or peeling.

2. Water retention: Hydroxypropyl methylcellulose (HPMC) has strong water retention and can absorb and retain moisture. In waterproof putty, hydroxypropyl methylcellulose can help the putty retain sufficient moisture, extend its working time, make construction more flexible, and reduce the risk of cracks in the putty during the drying process.

3. Anti-peeling: HPMC has good adhesion, can effectively combine with the surface of the substrate, and form a uniform mixture with other ingredients. This excellent adhesion can improve the peeling resistance of waterproof putty, allowing it to adhere more firmly to the wall, increasing the durability and reliability of the waterproofing effect.

4. Enhance construction performance: HPMC has excellent rheology, which can improve the construction performance of waterproof putty. It makes the putty easier to apply, smooths out, and improves filling performance, making construction smoother and reducing waste and construction time.

As a professional hydroxypropyl methylcellulose (HPMC) supplier, we combine a large amount of data from our HPMC products and local environmental testing through the use environment of global cooperative units. The hydroxypropyl methylcellulose we provide as a component of waterproof putty can not only improve the adhesion and water resistance of the putty, but also improve the construction performance, ensure the quality and effect of the putty construction, and make it more suitable for use in humid environments. waterproof treatment.
