Product overview

Hydroxypropylmethylcellulose (Hypromellose), also known as hydroxypropylmethylcellulose, is one of the mixed ethers of nonionic cellulose.It is a semi-synthetic, inactive, viscoelastic polymer, often used as a lubricant in ophthalmology, or as an excipient or excipient in oral drugs.

Applications

Construction industry

1. Cement mortar: improve the dispersion of cement and sand, greatly improve the plasticity and water retention of the mortar, and have an effect on preventing cracks and enhancing the strength of the cement.

2. Ceramic tile cement: improve the plasticity and water retention of pressed ceramic tile mortar, improve the adhesion of ceramic tiles, and prevent pulverization.

3. Coating of refractory materials such as asbestos: As a suspension stabilizer and fluidity improver, it also improves the adhesion to the substrate.
