HPMC YB 515M is a specific grade of Hydroxypropyl Methyl Cellulose developed specifically for premium tile adhesives.        The growing adoption and usage of tile adhesive and grout products have resulted in an increased demand for high-quality building material grade cellulose ether like EipponCell.        This trend has created market opportunities for Icap to expand its production capacity in response to rising demand. According to the annual cellulose ether data, the tile adhesive grade cellulose ether produced by Yibang company is a building material grade HPMC with a gel temperature of 75°C.        This gel temperature specification indicates the temperature at which the HPMC solution transitions from a liquid to a gel-like consistency.        By providing a cellulose ether with a gel temperature of 75°C, Yibang company ensures that their product is well-suited for use in tile adhesive applications, providing the desired performance and functionality required for premium tile installations. With the utilization of HPMC YB 515M in premium tile adhesives, Elbaz aims to meet the increasing market demand for reliable, high-performance tile installation materials that contribute to the growth of the construction industry and enhance the overall quality and durability of tile installations.

Application of HPMC YB 515M

EipponCell HPMC YB 515M, specifically designed for standard tile adhesive applications, possesses the following properties:

Influence on the open time of tile adhesive

​When latex powder and cellulose ether HPMC are present in a wet mortar, RDP powder exhibits a stronger binding energy with the cement hydration product, while cellulose ether primarily affects the interstitial fluid, affecting the viscosity and set time of the mortar.

RDP powder exhibits enhanced attachment to cement hydration products, while cellulose ether primarily affects interstitial fluid, affecting mortar viscosity and set time.

The coexistence of latex powder and cellulosic ether HPMC in a wet mortar affects the properties of the mortar, with RDP powder having a larger binding energy and cellulosic ether affecting the viscosity and setting time through its presence in the interstitial fluid.

Influence on the pull-out strength of tile adhesive

Cellulose ether in the mortar not only provides beneficial properties, but also delays the hydration dynamics of the cement by adsorbing onto the hydrated product instead of the original mineral phase.  This retardation effect is attributed to the reduced mobility of the ions in the pore solution due to the increased viscosity caused by cellulose ether.

The presence of cellulose ether in cement systems retards hydration kinetics by adsorbing the hydrated product instead of the original mineral phase, while also increasing the viscosity of the pore solution, thereby reducing ion mobility and further slowing down the hydration process.

Cellulose ether's retardation effect on cement hydration is primarily achieved by its adsorption onto the hydrated product and the subsequent increase in the viscosity of the pore solution, which hinders ion mobility and delays the overall hydration dynamics.
