Ciba Coating Effects Segment 

 CIBA (R) EFKA (R) 2020 

 Overview EFKA-2020 solvent-based coatings can accelerate the foaming process can be very effective to eliminate the bubble, regardless of the reason is due to the substrate, or the production process or application into the bubbles 

 Chemical composition of non-silicone defoamer 

 Physical properties of solvents: Special boiling point alcohols (140 - 165 oC) Density (20 ℃): 0.76 - 0.80 g/cm3 DIN 51757 Refractive index: 1.425 - 1.435 DIN 53491 Flash Point: 30 ℃ ISO 3679 Color: Up to 7 ISO 4630 Appearance: clear, light yellow liquid 

 Application of EFKA-2020 is particularly suitable for the following systems: * nitro and acid curing wood coating systems, especially flow coating or spraying paint brush approach * The two-component polyurethane systems * types from dry epoxy system (such as epoxy - polyamide system) 

 Recommended dosage 0.1 - 0.7% by total formula EFKA-2020 can be added prior to production, if, add, EFKA-2020 need to ensure good dispersion in the system 

 Safety and operating: EFKA 2020 should strictly abide by the operating practices of industrial chemicals, detailed information, please refer to the product safety data sheet (MSDS)
