LIVESTER BFAT A GLANCE

Outstanding performances for PES fibers and their blends dyeing with disperse dyestuff.

Free from critical chemicals of concern for human andenvironmental health. Benzoates free.

In 100% PES dyeing goods, it allows to achieve excellent exhaustion of the disperse dyestuff also attemperatures lower than 130°C, for hanks, bobbins andfor fabrics in beam and jet.

Outstanding application at boiling point (OBA):no pressure equipment needed.

Perfect for uneven shades recovery.

ODORLESS: improved workplace environment condition.

Light and wet fastness are not affected; easily removed by washing after dyeing.

Excellent dispersing power
