Description

SG-540 is a highly efficient rheological additive supplied as a soft paste dispersed in xylene. It is designed for giving excellent anti-settling in solvent-based industrial coatings without significant viscosity increase.

Advantages

• Excellent anti-settling properties and prevention of hard caking in can
• Easily dispersible using conventional dispersion devices such as high-speed mixers as well as high shear sand, pebbel and roller mills
• No significant viscosity increase under normal condition
• Suitable for high solid coatings and marine coatings

Physical Properties

• Apperance : Translucent yellowish soft paste
• Non-Volatiles : 39 ~ 41%
• Specific Gravity : 0.86 ~ 0.90
• Solvent : Xylene

Incorporation

High shear conditions and heat (30~60°C) are both required for proper activation and dispersion of SG-540, but preferable to increase the temperature to minimum 45°C for excellent performance of industrial coatings. It should be added during the dispersion stage, preferably pre-mixed in vehicle before the addition of other mill base components.

Recommended Levels

The typical addition level will vary depending on the type of coatings formulation. Recommended amount is 0.5 ~ 0.8% based on total formulation weight. In the case of industrial coatings with pigments having high specific gravity, the use of higher level of SG-540 is highly required.

Storage

SG-540 should be stored in the tightly closed original container in a cool and dry place at 5 ~ 30°C. Avoid exposure to heat source and direct sunlight. Under recommended storage condition, SG-540 may be stored up to 12 months.

Packaging

16 Kgs in tin can, 170 Kgs in drum.
