Application


  • ADDSiL™ 3278 is a versatile silicone additive designed to enhance wetting, flow, and leveling properties in various coating systems. It is particularly effective in waterborne, solventborne, and radiation-curable (UV/EB) coatings and inks, promoting uniform finishes and reducing surface defects. Its ability to lower surface tension makes it suitable for high-gloss finishes and applications on challenging substrates in industrial and architectural coatings.

Packing and Storage


ADDSiL™ 3278 is supplied in 25Kg/Pail or 200Kg steel drum or according to customer’s request.


When stored at temperatures between 10°C and 35°C in the original unopened containers, ADDSiL™ 3278 has a shelf life of 24 months from the date of production.
