Performance
A. Water retention
GRAD®HPMC has good water retention performance, prevents moisture from penetrating into the base surface too quickly, and has stable water retention capacity in a wide temperature range.
B. Thickening
GRAD®HPMC can make the mortar reach a suitable viscosity, improve cohesion, improve operability, resist sagging, and improve construction efficiency.
C. Suspension
In some scenarios, GRAD®HPMC provides suspension for the mortar without changing the consistency of the mortar, so that the mortar system is evenly dispersed without sedimentation.
D. Adhesive
The wetting ability of GRAD®HPMC can not only improve the viscosity of mortar, but also ensure the surface activity and cohesion of mortar.
E. Open time
Modified HPMC for ceramic tile adhesives with an ultra-long open time of over 35 minutes. The slippage is less than 0.5 and complies with various national standards such as C1TE and C2TE.
