EIFS/ETICS - Cellulose ethers-Redispersible Polymer Powder-Drymix mortar additives

Exterior Insulation Finishing System (EIFS), also known as External Thermal Insulation Composite Systems (ETICS), is a multi-layered cladding system that provides insulation and waterproof surface for exterior walls to improve the insulation effect of buildings. EIFS is composed of a heat insulation board as the primary material made of expanded polystyrene or mineral wool. It also contains an adhesive for bonding the insulating board to the substrate. It is then covered with a cement base coat with woven glass fiber reinforcement and a textured colored finish coat.

HPMC powder:

• 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.
