Application﹥﹥

● Latex Paints

Can be polymerized with vinyl acetate emulsion to improve stability of polymerizing system within wide range of PH value. In the finished product manufacturing, HEC used as a role of dispersion, stabilization and thickening in paint, especially high-PVA coating, providing excellent coating properties.

● Construction & Building Materials

Used as thickening agent and adhesive for cement and dry mixed mortars. As its good water retention, it improves the liquidity and performance of mortars and extends open time. Also HEC can improve water retaining ability and adhesive strength when used in wall plasters, render mortars, adhesive plasters and gypsum putty.

● Petroleum Drilling

Used as thickening agent to make mud achieve good mobility and stability, easy for mud pump which is required by drilling, well set, cementing and fracturing operations.

● Personal Care

Guarantee the stability of paste and improve the taste as its strong salt and acid resistance. Besides, water retaining ability and emulsifying capacity make toothpaste difficulty to dry.

● Water Based Ink

Help ink dry and fast penetrate. Moreover, it’s also widely used textile printing and dyeing, paper making, daily chemicals and so on.

● High Molecular Polymer

Used as dispersant for suspension polymer such as styrene, acrylate, acrylonitrile etc.

Product Package﹥﹥

● 20Kg or 25Kg net paper compound plastic bags with PE inner liner,water proofing.

● On clients’ requirement

Storage﹥﹥

Stored in dry and well-ventilated place, avoid direct sunlight, rain and humidity and keep sealed condition.
