Sourcing multiple construction chemical additives from different manufacturers brings many troubles: inconsistent product compatibility, complicated supplier management, longer lead times and extra quality risks. Dry‑mortar factories and overseas importers expect a trusted manufacturer who can deliver complete cellulose ether and RDP products in one place.
KINGMAX provides professional one‑stop solution covering HPMC, MHEC, HEMC, HEC and redispersible RDP powder. All products are independently produced in our own factory instead of resourced from third‑party vendors. Buyers can get all core dry‑mortar additives from a single source, simplify procurement workflow and reduce uncertainties caused by multi‑supplier cooperation.
Full‑Range Product Line Under One‑Stop Solution
HPMC (Hydroxypropyl Methyl Cellulose)
As the core additive for cement‑based systems, KINGMAX HPMC delivers excellent water retention, thickening and anti‑sag performance. It is widely used in interior & exterior wall putty, tile adhesive, plastering mortar and repair mortar. Multiple options including anti‑sag grade, low‑ash grade and various viscosity grades are available for ordinary and high‑end formulas.
MHEC (Methyl Hydroxyethyl Cellulose)
Specially developed for gypsum‑based mortar. MHEC maintains stable water retention within gypsum environment, prevents surface crust, premature drying and incomplete hydration. It ensures smooth troweling and uniform hardening for gypsum plaster, gypsum joint filler and gypsum self‑leveling mortar.
HEMC (Hydroxyethyl Methyl Cellulose)
Features outstanding high‑temperature resistance and weather resistance. Even under hot and windy outdoor construction conditions, HEMC locks moisture steadily. It is the preferred additive for exterior wall putty, external thermal insulation composite system mortar and outdoor repair mortar, effectively lowering shrinkage cracking and powder‑falling risks.
HEC (Hydroxyethyl Cellulose)
High‑efficiency thickener and stabilizer for water‑borne architectural coatings, liquid putty and special dry mortar. HEC optimizes suspension and leveling performance, avoiding particle sedimentation and layered separation of finished materials.
RDP Redispersible Polymer Powder
Matched RDP powder works synergistically with cellulose ether series. It forms flexible polymer film inside mortar matrix, improving bonding strength, flexibility, water resistance and freeze‑thaw durability of hardened mortar. Different film‑forming strength grades can be selected for tile adhesive, flexible putty, ETICS mortar and repair mortar.
