Product description

EFS-360 is a solventless, reactive, epoxy functional polysiloxane pre-polymer with a narrow molecular weight distribution.   EFS-360 chemically reacts with amine functional resins that contain amine groups

FEATURES & BENEFITS

• Provides faster curing systems – 2-3 hours
• Optimizes flexibility, reducing brittleness associated with standard epoxy-polysiloxane blends
• Superior chemical resistance at reduced coating weights
• Compatible with organic resins such as, epoxies and acrylics.
• Improved weatherability and heat resistance
• Increase corrosion resistance in epoxy-polysiloxane coatings
• Low viscosity allows for very low-VOC formulating
• Allows isocyanate free, ambient cure systems
• Facilitates epoxy-polysiloxane hybrid and copolymer formulations
• Easy handling

Application

EFS-360 pre-polymer used in combination with epoxies and acrylics resins via cold-blends to improve weatherability and heat resistance.

Guide formulations are available on request.
