Description

SG-520 is a highly efficient rheological additive supplied as a pourable paste dispersed inxylene. It is designed for giving excellent anti-settling in solvent-based industrial coatings without significant viscosity increase.

Advantages

• Prevents pigment settling without significant viscosity increase
• Give manufacturing economics due to easy transfer and dispersion
• Can be used with other rheological additives for synergistic effects
• No significant gloss reduction
• Pigment suspension at low additive level

Physical Properties

• Apperance : Translucent to white soft paste
• Non-Volatiles : 19 ~ 21%
• Specific Gravity : 0.87 ~ 0.89
• Solvent : Xylene

Incorporation

High shear conditions and heat(30~60°C) are both required for proper activation and dispersion of SG-520, but preferable to increase the temperature to minimum 45°C for excellent performance of industrial coatings. It should be added during the dipersion stage, preferable 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 1~2% based on total formulation weight. In the case of industrial coatings with pigments having high specific gravity, the use of higher level of SG-520 is highly required.

Storage

SG-520 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-520 may be stored up to 12 months.

Packaging

16 Kgs in tin can, 150 Kgs in drum.
