Dispersible latex powder (referred to as RDP) is a white or nearly white, free-flowing powder produced by spray drying processes using polymers such as vinyl acetate-ethylene copolymer (VAE) as the core raw material, combined with polyvinyl alcohol protective colloids. Its core characteristic is the ability to re-disperse into a stable emulsion upon contact with water, perfectly replicating the chemical properties and bonding functions of the original emulsion. It serves as a key functional additive for "green, high-performance" dry mortar in the construction industry
Widely used in thermal insulation systems: interior and exterior wall insulation mortar, EPS line thin-layer plastering, exterior wall insulation plastering mortar, tile adhesive, joint compound, bonding mortar, repair mortar, shrinkage-free grouting material; plastering and leveling: gypsum plaster, leveling mortar, self-leveling mortar, decorative mortar; interior and exterior wall putty powder, dry-mixed paint, diatomaceous earth, waterproof mortar.

Hydroxypropyl methyl cellulose (HPMC) is a non-ionic polymer compound made by etherification modification of refined cotton. It is a white or almost white flowing powder, odorless and tasteless, soluble in cold water, and forms a transparent viscous solution. It has multiple core functions such as water retention, thickening, bonding, and film formation. Can be in
A stable hydration film is formed within the mortar and putty system, with a water retention rate of over 90%, which delays water evaporation, ensures sufficient hydration or stable dispersion of the substrate, and effectively avoids drying and cracking. Significantly improve the viscosity and thixotropy of the system, optimize leveling and anti sagging properties, making it easier to apply and less likely to flow during construction or processing, while reducing bleeding. Improve the adhesion between materials and various substrates, enhance cohesion, and make finished products more sturdy and durable.
Suitable for interior and exterior wall putty powder, plastering mortar, tile adhesive, insulation mortar, self leveling materials, etc., to improve construction performance, crack resistance, and durability. The addition amount is usually 0.1% -0.6%. other fields
Coatings, ink thickeners, stabilizers, PVC polymer dispersants, ceramic binders, daily chemical cleaning and care, digital printing, petroleum drilling, seed coating, etc

Special additive for water sand mortar in arch stone technology
The polypropylene fibers produced by Weiteng Company are pure fiber filaments without water or salt, with a high fiber content
Polypropylene fibers are made from polypropylene (PP) as raw material, melted at high temperature, and then cut into fiber strands of 3mm, 6mm, 9mm, and 12mm. They are used for putty, 6mm for crack resistant mortar, 9mm for fireproof coating, and 12mm for insulation particle mortar.
Special adhesive powder is an independently developed product by Weiteng Company, which produces crack resistant mortar with 8kg of special adhesive powder added. Its hardness exceeds that of 8kg of milk adhesive powder added, making construction effortless, non sagging, and cost-effective.
Adhesive mortar special additive
Special adhesive powder has good adhesion to organic materials such as polystyrene board and extruded board. Adding 5-8Kg per ton of adhesive mortar results in high board breakage rate and low cost.
The main function of starch ether is to improve the fluidity of cement-based materials such as mortar putty. Adding 0.3-0.5kg per ton can make the mortar smoother, easier to scrape, and very effective for thin layer construction.
Starch ether can significantly improve the anti sagging and anti sagging properties, and is an essential material for producing special ceramic tile adhesives.
Poplar wood fiber is made by physically processing natural wood and adding it to cement products. When it comes into contact with water, the moisture can be quickly transferred to the surface and inner layer of the mortar, making the moisture distribution uniform, improving water retention and workability. Moreover, the wood fiber has not undergone chemical treatment, making the product more stable.
And poplar wood fibers have a certain degree of water retention, which can absorb some of the water retention of cellulose, making the quality of mortar more stable.
Poplar wood fiber also has a certain degree of thixotropy and lubricity, and it works better when used in combination with starch ether.
