Kraton polymers are linear triblock copolymers based on styrene ethylene butylene styrene (SEBS), which are added to varnishes based on Regalrez to make the film more flexible.Kraton G-1650 is soluble in medium- and low-polarity solvents, but not completely soluble in aliphatic hydrocarbons. Kraton G-1650 should be always used in conjunction with Tinuvin 292that increases its stability.
