German technical background VOK®- 407 silicone leveling agent

Overview: Polysiloxane products, with good thermal stability and water repellency, low surface tension, high dielectric strength, can be used in various industrial applications with good results.

Composition: polydimethylpolysiloxane complex

Appearance: transparent liquid Specific gravity: 0.970-0.978

Viscosity: 320-367cps

Surface tension is about 21.1dynes/cm

Nonvolatile: 99.99%

Scope of application

Various solvent-based coatings and inks

Characteristics and use

Reduce the surface tension and add it to the coating to reduce the defects such as pits and oil spots on the coating surface caused by the substrate grease and release agent pollution.

It has a good effect on the flow, leveling and smoothness of the coating film.

In anti-floating color. Flowering and defoaming have special performance.

It is also a good release agent, antifoam agent, lubricant and brightener in other industries.

Addition amount and use method

Defoaming: 0.1-0.2% of the total amount

Resistance to pits, oil spots, or promote leveling, 0.1-0.2% of the total amount

Anti-floating color blossoming, for total amount: 0.002-0.005%

be careful

Because the amount added is very small, please dilute it for 10-100 times first.

Add 407 coating film. If you want to apply it, you need to add this product inside the coating to maintain adhesion and leveling.

When added to the transparent paint, there will be slight turbidity. Some parts will become transparent after the film is dry. Please test before use.

security

Avoid contact with skin and eyes. For other information, please refer to the Material Safety Data Sheet.
