C919A Active Thickening and Anti-settling Rheological Agent

1. Quality Specification

Appearance: Light white flowable powder

Volatile(105℃,2 hours):≤3.5%

Particle size (<76μm or 200 mesh):≥98%

Colloidal viscosity of 1%aqueous solution (mpa·s):≥3000

Colloidal viscosity of 10%ethanol (mpa·s):≥4000.

2. Characteristics and Application

When dispersed in alcohol ether solvents, the characteristic product can swell in water to form colloid to achieve ideal thickening thixotropy and sag resistance.

C919A is a new product improved on the basis of C919, with a wider range of products.

C919A is a light white flowable powder, and the product has good thickening rheological properties in water, alcohol, alcohol ether and their mixed solvents. When the product is added to water and other solvents at the beginning of dispersion, other components should be added to the dispersion machine first, and stirred at high speed for 20~30 minutes under high shear to achieve complete dispersion, or it can be made into pregel and then added to the system in the form of pregel. The amount of product added is generally 0.1%~1.0%of the total system, which can be determined by customers through experiments.

Widely used in:Waterborne and oily marine paints, industrial paints, waterborne and oily container paints, other waterborne industrial paints, inks, sealants, greases, etc.

3. Packaging and Storage

The outer packaging is kraft paper bag, and the inner packaging is double-layer packaging with polyethylene film bag or paper bag with valve port. The weight is usually 20±0.25kg or stored in dry condition according to user's requirements.When the temperature is 0°C~30℃, the quality has an effective period of 24 months.
