(1) Hydroxypropyl Methylcellulose (HPMC) is a cost-effective alternative to carbomer, it is widely used in leather, paper products industry, fruit and vegetable preservation and textile industry.
Hydroxypropyl Methylcellulose (HPMC) is used as paste tiles, marble, plastic decoration, paste enhancer, but also can reduce the amount of cement. The water retention properties of hydroxypropyl methyl cellulose make the slurry not crack after smearing and enhance the strength after hardening.
