SZPA aluminum zinc phosphate: The product has a higher phosphate content than zinc phosphate. Due to the absence of alkaline components, it exhibits universal anti-corrosion properties in many applications. It orderly increases the water-soluble components with inhibitory effects, thereby it can form a better protective layer on the metal surface. It has a longer lasting protective performance than zinc phosphate.
SZPO organic modified zinc phosphate: Organic modification makes it better combined with resin and have excellent rust prevention performance.
SZMP molybdenum modified zinc phosphate: The product is used to enhance rust prevention properties. Due to the synergistic effect of molybdenum and phosphate ions, it exhibits excellent rust prevention performance in many resin systems.
