Phoscoat Chem (Y-361) Zinc-Calcium Phosphating Solution
Fine Smooth Zinc Phosphate Coating at 60°C - 65°C
Phoscoat Chem (Y-361) incorporates modified zinc-calcium crystal modifiers that deposit an exceptionally dense, fine-grain crystalline lattice. Designed for premium automotive and electrical enclosure finishing, it ensures phenomenal mechanical powder coat interlock and passes 1000+ hours ASTM B117 salt spray testing with zero paint creepage.
Key Operational & Quality Advantages:
- Zinc-calcium modified chemistry produces ultra-fine microcrystalline structure
- Outstanding interlock adhesion for CED primers and polyester powder coatings
- Exceptional resistance to under-film corrosion creepage
