TP550

TP550 by Tech-power (Huangshan) is an acrylic resin with epoxy groups which acts as a pure polyester matting agent. It is also used as a curing agent for low-acid-valence (25-30) saturated carboxyl polyester. It offers good leveling, chemical-, weather-, hydrochloric acid-, high temperature- and yellowing resistance. It utilizes the compatibility difference between its components and polyester resins and the reactivity of its unique functional genes to form a complex network interpenetrating extinction with the main material. TP550 is recommended for powder coatings. The shelf life of the grade is 1 year.
