Aluminum Strontium Polyphosphate Hydrate KRONPHOS SRPP
Description:
Aluminum Strontium polyphosphate hydrate. It is mainly used for the COILING system and in aircraft primers and powder coatings. It exhibits high electrochemical efficiency due to its altered chemical structure. It is suitable for various types of coatings: water–based - based on alkyd emulsions, epoxides, polyurethanes, silicone resins, acrylic and modified acrylics and butadiene. Solvent–based - based on alkydes and epoxides with high solids content, epoxides and high-hardness polyurethanes, silicone resins.
Properties:
- Non-toxic, environmentally friendly product
- Being free of unwanted colour, the product can be used in primers and ground coats of any colour
- When introduced into a painting system, the product does not cause side effects
- When the coating composition with zinc phosphate is applied on the metal surface, a protective layer is created on the surface of the substrate, which interacting with oxygen creates phosphate complexes, protecting the metal from rusting
- Unlike organic corrosion inhibitors, the film-based coating demonstrates a lasting anti-corrosion effect
