● Building construction
It is used for brick laying, wall rendering, inlaying wall seams, it is suitable for dye-blending and pre-blending cement slurry and conductive to thickening, water-holding and coherence enhances adaptability to pump slurry.
● Decorative construction
It is used to stick up tiles and marble with high cohesive strength, at the same time it can decrease cement consumption. It also used for plastering with good workability and without cracking.
● Coating
It is used as thickening agent which makes coated surface lucent. lustrous and fine, not peeling off, improving the fluidity.
● Colorful ceramic glaze
It is used as suspension agent and cohesive agent, it makes pigment disperse uniform in glaze and thicken coated layer due to the gelling feature.
It also finds wide applications as the agent of thickening, coherence, moisture-holding, film-forming, stabilizing, emulsification, shaping etc. in petrochemicals, building, printing & dyeing, tobacco, daily-use chemical, paper-making, leather, agriculture and forestry and others.
● Packing, Storage
Packing : 20kg or 25kg net weight in fiber drum, paper-plastic compound bag lined with 2 inner PE bags. 25kg in multiply paper bags with polyethylene inner and supplied on pallets with film shrink.
Storage: Exposing to the sun and rain is forbidden to avoid fire and absorption of moisture, seal tightly, and keep at ventilated place.
