Product Introduction
Hydroxyethy Cellulose (HEC for short) .its nonionic thickerner.It is widely used in latex paints,building materials,oilfield chemicals,home care and personal care products and most of the water born systems.
It can be used in wide PH range and different emulsion systems;High compatibility with pigment paste;Excellent water retention;Excellent viscosity stability upon tinting;Excellent storage viscosity stability.
Application
Thickeners: latex paints,paper coatings,emulsion synthesis,cosmetics,clothing and textile printing inks and adhesives.
Ashesive:color ceramic glazes,refractory,color refills,burn-binding materials,repair mortar and tile adhesive.
For bending: the fabric sizing,surface coating glass fiber sizing,sizing and absorbance impervious to the processing of oil and transparency.
The acidic thickened: metal cleaning,acid treatment and acid strata wells.
Water loss control: portland cement for oil well with cement,a dilute type tile mortar and applied to porous strata and surface water loss control.
