What is the main role of HPMC in the application of putty powder?

HPMC has three functions of thickening, water retention and construction in the application of putty powder. Thickening: cellulose can thicken, play a role in suspension, keep the solution uniform up and down, and resist sagging. Water retention: make putty powder dry slowly, and assist lime calcium to react under the action of water. Construction: cellulose […]

Properties of redispersible emulsion powder

1. Redispersible emulsion powder can form a film after dispersion and play a reinforcing role as the second adhesive; The protective colloid is absorbed by the mortar system (it will not be destroyed by water after film formation, or “secondary dispersion”); The film-forming polymer resin is distributed in the whole mortar system as a reinforcing […]

VAE Redispersible Powders (RDPs) in Building & Construction

Vinyl acetate-co-ethylene copolymers (VAE) in powder form are white, free-flowing, dry powders that can be easily redispersed into water to form a stable emulsion. Often referred to as “solid latex,” VAE redispersible powders (RDPs) are easier to ship, store (thanks to excellent storage stability), handle, and dry-mix compared to VAEs in emulsion form. VAEs dominate […]

What’s the effects of HPMC for the Cement-Based Building Material Mortar

1.Water-Holding Capacity Hydroxy Propyl Methyl Cellulose (HPMC) helps to significantly improve the water-holding capacity of mortar. Just a low level of hydroxypropyl methyl cellulose addition can lead to a significant improvement in the water retention rate of the mortar. When the addition level is 0.002%, the water retention rate increases from 83% to 88%; while […]

Benefits of HPMC in Construction

Improved Workability HPMC improves the consistency and ease of application of construction materials, making them easier to spread and apply. Enhanced Water Retention It significantly increases the water retention capacity of cement and gypsum-based products, preventing premature drying and improving the curing process. This leads to better strength development and reduced risk of cracks. Increased […]
