What kind of viscosity is suitable for the hpmc in the caulk & filling agent?

Ceramic tile grouts have the advantages of waterproof, mildew-proof, scrubbing resistance and rich color. 1. Waterproof function: The ceramic tile surface and the filler filling between the ceramic tile seams form a complete waterproof layer, which avoids water seeping into the wall from the brick seams and causes the ceramic tile to fall off. 2. [...]

How to dissolve HPMC(Hydroxypropyl Methyl Cellulose) correctly? What is the specific methods?

HPMC can be divided into instant type (Surface treated) and hot soluble type (Non-surface treated). The instant product is rapidly dispersed in cold water and disappears into the water. At this time, the liquid has no viscosity because HPMC is only dispersed in water and there is no real dissolution. About 2 minutes, the viscosity [...]

How to choose the right hydroxypropyl methylcellulose

The relationship between water retention and viscosity of hydroxypropyl methylcellulose is not a proportional relationship within a certain viscosity range, but also depends on the practical application of the product. Relatively speaking, when hydroxypropylmethylcellulose has a viscosity of more than 100,000, the difference in water retention between 100,000 viscosity and 200,000 viscosity is not large. [...]
