HPMC is the right material for you if you want to increase the tensile strength of gypsum plaster and other construction material. It acts as an interface agent. That is, it improves gypsum plaster flexural strength and increases bonding strength.

Hydroxypropyl methyl cellulose (HPMC) has excellent water retention properties and is widely used in various mortars, including masonry mortar, plastering mortar and ground leveling mortar, to improve the bleeding of mortar.

VAE Redispersible Powders are a type of polymer powder produced through the spray drying of a mixture of vinyl acetate and ethylene. Once dispersed in water, these powders form stable emulsions that can be easily integrated into cementitious materials.

HEMC can be used as a highly efficient water retention agent, adhesives and film-forming agent, stabilizer, etc. It is widely used in different industrial applications such as oil drilling, construction, and building, paint and coating, pharmaceutical, etc.

In general, the gel temperature of HPMC is around 60℃-75℃ depending on its group content and different production technique. Due to the characteristics of MHEC group, it has a higher gel temperature, usually > 80℃.
