Key Features and Typical Benefits

• Reduced water uptake and improved UV resistance in latex systems
• Outstanding thermal and UV resistance as a sole binder
• A more flexible coating as a cobinder with acrylic latex without detrminetal effects on dirt pick-up
• Compatibility with a variety of waterborne polymer systems, including many:
  • Acrylics
  • Styrene Acrylics
  • Epoxies
  • PUDs
  • Alkyds

Potential Applications

• Roof coatings
• Exterior coatings
• Wood coatings

CoatOSil DRI waterborne silicone is used as a co-binder for the modification of latex resins in coatings as well a sole binder when thermal and UV resistance need to be maximized. CoatOSil DRI waterborne silicone is compatible with many acrylic, styrene acrylic and PUD resin systems. It is used most often in applications requiring increased thermal, UV, water resistance, or elongation properties of a coating system. Key features and typical benefits of CoatOSil DRI waterborne silicone for latex systems include:

• Reduced water uptake
• Increased UV resistance
• Increased thermal resistance
• Increased flexibility and elongation
• Excellent compatibility

CoatOSil DRI waterborne silicone has also shown potential for use in both low PVC and high PVC (matte) paint formulations. In a sample satin PVC formulation, tests showed improvements in gloss retention and a reduction in both color fading and water absorption.

The attached technical paper features CoatOSil DRI waterborne silicone and was first published in the European Coatings Journal, issue 10/2016. For more information about how to enhance and protect with CoatOSil waterborne silicone resin, click here.
