HEC Hydroxy Ethyl Cellulose
Vamcell Hydroxy ethyl cellulose
Vamcell is our registered trademark of Cellulose ethers.
Introduction:
Vamcell HEC is a nonionic surfactant and odorless, free flowing white powder. HEC is characterized by hygroscopicity and can be dissolved in both cold and hot water. It has high thickening effect, excellent rheological properties, suspension, adhesion, emulsification, filming, watering and protective colloid properties.

Application:
Latex Paints
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
