Coatings Grade Dispersant Agent Thickening Agent HEC Paint Additive

Basic Info

Product Description

• Hydroxyethyl cellulose(HEC) is a gelling and thickening agent derived from cellulose. HEC is non-ionic, water-soluble materials that provide good properties of thickening, suspending, binding, emulsify, film-forming, stabilize, disperse, retain water and etc.
• And It is widely used in coatings, construction, medicine, food, papermaking and polymer polymerization industry. In medicine field, Hydroxyethyl cellulose and methyl cellulose(MHEC) are frequently used with hydrophobic drugs in capsule formulations, to improve the drugs' dissolution in the gastrointestinal fluids.

1.0 Presentation of Product

HEC is made from natural polymer cellulose, is non-ionic water-soluble polymer, it is white to
slight yellow, odorless and tasteless powdered solid.

2.0 Quality of Product

HEC non-ionic water-soluble polymer,is effective in thickening, bonding,emulsifying,dispersing,
stabilizing and water preserving, forms film and provids protective colloid effect. It is very easily
soluble not only in cold water, but also in hot water,and can provide solutions with wide range of
viscosity.

3.0 Product Applications

HEC is the most commonly used thickener in Latex painting. In addition to thickening to the Latex
paint. It has functions of emulsifying,dispersing,stabilizing and water-retaining, it is characterized
by the significant thickening effect, excellent color development, film forming and storage stability.
HEC is non-ionic cellulose ether which can be used in a wide range of pH values. It has
good compatibility with other material,such as pigment,auxiliaries,filers and salts,good workability
and leveling performance. Application methods including brushing rolling and spraying could be
used. HEC has good workability and leveling effect. Having been applied, it is not easy to drip,sag
or spatter.

4.0 The Method of Hydroxyethyl Cellulose Used in Latex Paint

Directly adding with grinding paint
1) in the vat with high cutting agitator adding appropriate purified water (under general conditions,
ethylene glycol, wetting agent and film former etc. All added in this step.).
2) Stir constantly and slowly add hydroxyethyl cellulose in the solution uniformly, continue to stir
until all particulate matter drenched.
3) Then adding the preservative, alkaline additives, etc, such as pigment dispersing agent.
4) Stir until all hydroxyethyl cellulose completely dissolved (solution viscosity increased significantly),
then adding other constituent which in the formula, grinding till to paint.
