EipponCell HPMC YB 540M is a specific type of hydroxypropyl methylcellulose (HPMC) ether that is specifically designed for use in gypsum-based plaster and gypsum mortar products. When incorporated into gypsum-based slurry, HPMC YB 540M serves multiple functions, primarily as a water retention agent and a thickening agent. It effectively improves the adhesion and sag resistance of the slurry.

The high-quality EipponCell HPMC YB 540M can be uniformly and efficiently dispersed within cement mortar and gypsum-based products. It envelops all solid particles and forms a wetting film. Over time, the moisture present in the substrate is gradually released. This gradual release of moisture allows for a prolonged hydration reaction with the inorganic gelling material. As a result, the bonding strength and compressive strength of the material are ensured.

EipponCell HPMC YB 540M, when used professionally, enhances the performance of gypsum-based plaster and mortar. It acts as a water retention and thickening agent, improving adhesion and sag resistance. It disperses uniformly within the material, forming a wetting film that gradually releases moisture, thereby promoting long-lasting hydration reactions and enhancing the bonding and compressive properties of the material.

Application of HPMC YB 540M

EipponCell HPMC YB 540M is suitable for cement-based plaster due to its impressive properties:

Easy and smooth application: This allows for an effortless and seamless hanging of the plaster. ​The material can be easily molded in one go, providing excellent workability while maintaining its plasticity.

Strong compatibility: It is compatible with a variety of plaster bases, reducing the time required for plaster to settle and minimizing drying shrinkage.. This compatibility helps prevent issues such as hollowing and cracking, ensuring a more durable wall finish.

Effective water retention: The EipponCell HPMC YB 540M retains water effectively, extending the operational time of the gypsum base. This property improves the resistance to thickness reduction, enhances the bonding strength between the gypsum substrate and the underlying layer, and exhibits good wet-bonding properties.. It also helps reduce problems such as ash formation during drying.

Enhanced spread rate: Compared to similar hydroxypropyl methylcellulose ethers, EipponCell HPMC YB 540M significantly improves the spread rate. This means that it can cover a larger area with the same amount of product, resulting in increased efficiency, reduced labor intensity, material savings, and improved overall economic benefits.

Excellent anti-sagging performance: When applying thicker layers, EipponCell HPMC YB 540M exhibits exceptional anti-sagging properties. It remains stable and does not sag during single-pass construction.. Even with multiple passes and thicknesses exceeding 3 cm, it maintains its integrity and plasticity, ensuring a reliable and aesthetically pleasing finish.
