CoatOSil 1211C

Non-foaming wetting agent for waterborne coatings and inks. Ideal for hard to wet surfaces.

Momentive Performance Materials CoatOSil 1211C coatings additive is uniquely engineered and may impart non-foaming and superwetting properties in waterborne coatings for spray applications, high speed roll applications and hard to wet surfaces. It is a 100% active, organomodified silicone that should not interfere with recoatability. It may be an effective replacement for fluorosurfactants in many applications, yet it does not cause the foaming problems often associated with fluorosurfactants. It may also be used in solvent-based and radiation-curable coatings and may enhance the wetting power of the coatings formulations.

Key Features and Benefits

• Helps enable wetting of waterborne systems on hard to wet as well as standard substrates
• May enhance coatings uniformity
• May enable wetting with reduced levels of coalescing agents, hence reduces the levels of volatile organic compounds (VOC) in coatings formulations
• Does not cause foaming in waterborne coatings or inks
• Does not affect recoatability
• May improve dispersion stability of pigments, and color acceptance

Potential Applications

CoatOSil 1211C coatings additive may provide the greatest benefit in waterborne formulations to be applied to hard to wet substrate. The non-foaming characteristics may make it well suited for use in coatings applied by spray or high speed roll methods. Possible applications for coatings containing CoatOSil 1211C coatings additive include:

• Coatings for plastic films and plastic components
• Wood coatings
• Glass coatings
• Coatings applied to contaminated (oily) metal surfaces
• Spray or high speed roll applied coatings
