Features & Benefits

CASE Ingredients Features

Improved Substrate Wetting

Product Highlights

• Helps wetting of waterborne systems on hard-to-wet as well as standard substrates

• Typically does not cause foaming in waterborne coatings or inks

• Enhanced coating uniformity

• By enabling reduced use levels of coalescing agents, can help reduce the levels of volatile organic compounds (VOC) in coatings formulations

• Typically does not affect recoatability

• Improved dispersion stability of pigments and color acceptance

Recommended Uses

CoatOSil 1211C coating additive may provide the greatest benefit in waterborn  formulations to be applied to hard to wet substrates.

The non-foaming characteristics may make it an excellent candidate for use in coatings applied by spray or high-speed roll methods. Possible applications for coatings containing CoatOSil 1211C coating additive include:

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

Instructions For Use

CoatOSil 1211C coating additive may be used in various waterborne formulations having pH 6.5-8.5. Surface Tension data indicates that efficacy of this additive can be pH sensitive, especially in highly alkaline formulations. Therefore, full
formulations testing with CoatOSil 1211C coating additive is recommended.

CoatOSil 1211C coating additive can be added to the formulation in the grind or during the letdown process. It should be added slowly under low agitation, gradually increasing the mixing speed and allowing the wetting agent to disperse at moderate shear for 5 to 15 minutes. Improper dispersion of the additive may cause surface defects in some
systems. Alternatively, it can be mixed with co-solvent and incorporated into the formulation. If the formulation has been sitting for a long time, mix well before use.

When CoatOSil 1211C coating additive is added to the grinding resin, it can provide better pigment wetting and help prevent pigments from flocculating. This can result in better storage stability, improved gloss and color acceptance.

CoatOSil 1211C coating additive at starting levels of 1 to 4 pounds per hundred gallons of coating is recommended.
A ladder study is recommended to determine optimal usage levels.
