CASE Ingredients Features: Mar Resistance,
Slip Resistance
Product Highlights: Most Powerful COF Reducer in Momentive Performance Materials Portfolio CoatOSil 3501 coatings additive provides more COF reduction in radiation-cured systems than Silwet* L-7602 surfactant, and even than CoatOSil 3573 coatings additive or CoatOSil 3500 coatings additive.

Non-Foaming in Acrylates There is no foam generation in acrylated formulations.

Excellent Defoamer The product provides defoaming action in conventional and high-solids solvent-borne coating systems, and is an extremely potent defoamer in waterborne and waterreducible coating systems. Note that in this latter application, it is best used in combination with a water-dispersible material, such as Silwet L-7602 surfactant, to prevent defects.

Enhanced Slip and a Mar Resistance It also improves slip and mar resistance in variety of coating systems: waterborne and water-reducible, as well as conventional and high-solids solvent-borne.

Processing Recommendations: To prevent coating defects and other incompatibility problems, CoatOSil 3501 coatings additive should only be used in conjunction with more compatible materials, such as CoatOSil 3500 coatings additive or Silwet* L-7602 surfactant. When used alone at 0.5-1% in acrylate coating systems, CoatOSil 3501 coatings additive may cause severe orange peel and gloss reduction. However, when used in combination with Silwet L-7602 surfactant, this incompatibility can be controlled. Thus, one can balance defects against COF reduction. Good starting points are 5-10% CoatOSil 3501 coatings additive with Silwet L-7602 surfactant used at 1% total additive. If defects still occur, try lower ratios. If there are no surface defects, higher ratios will decrease COF even more.
