SYLFAT LCTM is Kraton’s best offer with respect to low initial color and high color stability in alkyd coatings.

SYLFAT LCTM is a better alternative combining all main properties compared to SFFA.

SYLFAT™ 2 is Kraton’s best offer when color is off a somewhat lesser importance . It combines the best film properties required by the alkyd paint.
