Selecting a reliable construction chemical supplier is the foundation of stable dry‑mortar production. Unstable viscosity, fluctuating water retention, poor product compatibility and incomplete export documents will bring huge hidden risks to your finished goods, production schedule and overseas customs clearance. More and more global buyers prefer to cooperate with real manufacturers rather than trading intermediaries to control quality and cost from the source.
KINGMAX is a trusted construction chemical supplier focusing on cellulose ether and redispersible polymer powder. We integrate R&D, production and quality testing in‑house. Our full‑series HPMC, MHEC, HEMC, HEC and RDP serve tile adhesive, wall putty, gypsum plaster, thermal insulation mortar and architectural coating industries. We commit to consistent product performance, responsive technical service and complete export support for partners worldwide.
Core Construction Chemical Product Portfolio
HPMC (Hydroxypropyl Methyl Cellulose)
As the mainstream additive for cement‑based systems, KINGMAX HPMC delivers excellent water retention, thickening and anti‑sag properties. It extends open time and optimizes troweling performance. Widely used in interior & exterior wall putty, tile adhesive, plastering mortar and repair mortar. Anti‑sag, low‑ash and multiple viscosity grades are available for ordinary and high‑end formulas.
MHEC (Methyl Hydroxyethyl Cellulose)
Optimized for gypsum‑based mortar systems. MHEC maintains stable water retention under neutral‑weakly acidic gypsum environment, preventing surface crust, premature drying and insufficient gypsum hydration. It guarantees smooth construction and uniform hardening for gypsum plaster, gypsum joint filler and gypsum self‑leveling mortar.
HEMC (Hydroxyethyl Methyl Cellulose)
Outstanding high‑temperature resistance and outdoor weather resistance. Even under hot and windy exterior construction conditions, HEMC keeps stable water‑locking capacity. It effectively reduces shrinkage cracking and powder‑off issues for exterior wall putty and external thermal insulation composite system mortar.
HEC (Hydroxyethyl Cellulose)
High‑efficiency thickener and stabilizer. HEC improves suspension and anti‑sedimentation performance, avoids material delamination. Mainly applied in water‑borne architectural coatings, liquid putty and special functional dry mortar.
RDP Redispersible Polymer Powder
RDP improves mechanical strength and long‑term durability of hardened mortar. It forms flexible polymer film inside mortar matrix, enhancing bonding strength, flexibility, water resistance and freeze‑thaw resistance. When compounded with cellulose ether, it produces obvious synergistic effect for high‑performance tile adhesive, flexible wall putty, ETICS mortar and repair mortar. Multiple film‑forming grades can match different formula standards.
