HEUCOPHOS® SRPP

HEUCOPHOS® SRPP by Sudarshan Chemical Industries is a zinc-free corrosion inhibitor. It is a high-performance pigment based on modified strontium aluminum polyphosphate hydrate. It is designed for powder coatings and UV cured systems.

• It possesses higher phosphate content compared to most orthophosphates, allowing excellent long-term protective behavior.
• It is a special adjustment of HEUCOPHOS® SAPP, and is used as a replacement of chromates in high-performance applications, mainly in coil coatings and aircraft primers.
• It exhibits high electrochemical effectiveness due to altered chemical structure design.
• HEUCOPHOS® SRPP is suitable for water-based coatings based on alkyd emulsions, 2K epoxies, 1K & 2K polyurethanes, silicone resins, acrylic & modified acrylics and butadiens (with low or no VOC).
• It is also used in solvent-based coatings based on high solids alkyds & epoxies (with low or no VOC), 2K epoxies, 2K- and high solids polyurethanes.
