In modern building exterior wall systems, External Wall Insulation Mortars (EWIM) and Skim Coats are critical for ensuring both the thermal performance and aesthetic finish of the system. However, whether it's a thick layer of insulation mortar or a thin layer of skim coat, efficient application on vertical surfaces demands extremely high standards for the material's workability and sag resistance. Hydroxypropyl Methyl Cellulose (HPMC), an indispensable polymer additive, is the secret weapon for achieving these crucial rheological properties.
In exterior wall insulation systems, mortar acts as the crucial "bridge" connecting insulation boards to the wall, and its performance directly determines the safety and durability of the entire system. Hydroxypropyl Methyl Cellulose (HPMC) is the key core additive that ensures exterior wall insulation mortar meets these high standards.
Hydroxypropyl Methylcellulose (HPMC) is an essential additive in modern dry-mix construction materials. As a high-performance cellulose ether, HPMC improves water retention, enhances workability, and provides consistency in various mortar systems.
