Unleashing the Potential of HPMC in Gypsum Plaster and Beyond
October 22nd 2024
Hydroxypropyl methyl cellulose(HPMC)-short name Hypromellose. HPMC is off-white powder in appearance. HPMC could dissolved in water and forms colloids. It is no-toxic. Dry mix mortar is one of HPMC main applications, hereby, we will let you know the detailed functions of HPMC in tile adhesive application.
● Tensile adhesion strength of cementitios adhesives
Based on European standards, the C1 and C2 ratings(specified in DIN EN12004) relate to tensile adhesion performance. The class c1 criteria represent the minimum requirements(min.0.5N/mm²) for all cementitious tile adhesives. The performance standards specified for class C2 are appreciably higher, with a minimum tensile adhesion strength of 1N/mm² required of thin-bed adhesives. Tensile adhesion testes for the C1 and C2 ratings are performed for for different storage conditions.
