Conclusions
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. initial drying properties hardness development gloss retention
Depending on what type of characteristics you are aiming for Kraton has the right product available for alkyd binder development. Kraton’s sustainable solutions and high supply security makes it a perfect partner for the supply of high quality products for the coatings industry.
