HPMC Hydroxypropyl Meethyl Cellulose for Coating Additive
Product Details: Hydroxypropyl Methyl cellulose (HPMC)
CAS No: 9004-65-3
Construction industry: As a water-retaining agent and retarder of cement mortar, it makes the mortar pumpable. Used as a binder in plaster, gypsum, putty powder or other building materials to improve application and prolong operation time. It can be used to paste ceramic tiles, marble, plastic decoration, paste reinforcement, and reduce the amount of cement. HPMC 's water-retaining properties prevent the paste from cracking because it dries too quickly after application, enhancing the strength after hardening.
