Description

CRAYVALLAC® PF is a modified micronized hydrogenated castor oil rheology modifier designed for easier handling and activation in powder form. Here are its typical characteristics and properties:

Nature: Castor derivatives
Appearance: Off-white micronized powder
Solid Content: 100%
Active Content: 100%
Specific Gravity: 1.01
Particle Size Distribution: DV.2 min: 2 µm / DV.8 max: 10 µm

Description:
CRAYVALLAC® PF is specially designed to facilitate incorporation in powder form, making it easier to handle. Upon activation, the fine particles of CRAYVALLAC® PF form an interacting network of fibers, resulting in shear-thinning rheology. This behavior ensures high viscosity under low shear rates and low viscosity under higher application shear rates, providing excellent control of sedimentation combined with ease of application. CRAYVALLAC® PF is suitable for various applications.

Recommended Addition Level:
0.2-3% under heat and shear.

Standard Packaging:
Available in 15 kg bags. Other packaging options may be available upon request.

Handling & Storage:
Store in the original containers in a dry place at temperatures between 5°C (41°F) and 30°C (86°F). Avoid exposure to direct sunlight or frost. Use within 48 months from production under these conditions.

Processing Instructions:
CRAYVALLAC® PF is best incorporated during the pigment dispersion stage using a high-speed disperser that generates the necessary shear and temperature. The increased specific surface area of its finer particles contributes to achieving maximum rheological performance.

Health and Environmental Data:
Refer to the Safety Data Sheet for safe handling. For more information about health and environmental data, contact the manufacturer.
