Hydroxypropyl Methyl Cellulose (HPMC) 150K - Cellulose ethers-Redispersible Polymer Powder-Drymix mortar additives

Hydroxypropyl Methyl Cellulose (HPMC) 150K

Hydroxypropyl Methyl Cellulose (HPMC) 150K leads to high sag resistance and long embedding time, which are the required key properties of EIFS and ETICS.

• Hydroxypropyl Methyl Cellulose (HPMC) 150K allows better sag resistance means that mortar can be applied more efficiently to walls without sag.

• Better leveling and reduced stickiness of cellulose can be applied easily to thick layers of EIFS and ETICS.


Hydroxypropyl Methyl Cellulose ( HPMC) 150K is high viscosity hydroxypropyl methyl cellulose, It’s mainly recommended for EIFS&ETICS and cement masonry mortar.
