Fluorine-acrylic hybrid polymer emulsion SIFCLEAR™

Highly functional fluororesin with excellent stain resistance

Product outline

SIFCLEAR™ is a water-based modified emulsion, obtained by alloying the vinylidene-fluoride polymer with the acrylic polymer at molecular level. It can be suitably used as a binder resin of waterborne paint for the exterior walls and roofs, anti-corrosive paint system, and thermal insulation paint. Characteristics of SIFCLEAR™ are as follows.

High transparency
Good water wettability
Outstanding stain-resistance
High weather resistance
Excellent flexibility and adhesion

Grade comparison chart

SIFCLEAR^™ shows outstanding stain-resistance compared to the competitive fluororesin.

Characteristics

Water wettability (Movie)

In spite of fluororesin, the coating film of SIFCLEAR^™ shows good water wettability, because of modification by acrylic resin.
Stain resistance (Outdoor exposure test)

The stain resistance of SIFCLEAR^™ coating film is so outstanding that it is difficult to get rain stain in the outdoor environment.
