METASU YC process

High corrosion resistance is achieved by applying a zinc-aluminum composite rust-resistant coating, enabling the service life extension of key parts for our customers.

Superior consistent coating performance prevents recess-fill problems

The excellent wettability and thixotropic performance of METASU YC create consistent coating and greatly reduces recess of the head

Self-healing feature makes it resistant against scratch and maintain consistent high corrosion resistance

A unique formula and technology make it highly resistant to corrosion even when the surface is scratched or damaged.

SST (Salt Spray Test) SST mode : JIS Z2371 (ISO 9227 ; 1990 (MOD))

  • 1500hr

  • 2500hr

※ SST test is performed after an impact wrench is used for 3 cycles of "tightening and loosening"
