Source documents supplied on 2026-10-01. Each row is an application reference for a different thickness condition, not a maximum-hour guarantee at every thickness. The baseline is unsealed for 100 and sealer-treated for 300/500. Control zinc plating, trivalent passivation and post-treatment, and test actual parts before application. SST hours do not represent service life.

PRODUCT & PROCESS
Upgrade 300 chemicals and process
Review the post-treatment system around UP300-A and UP300-B. For alkaline lines, also assess whether UP300AKL is required.
UP300-B — Main sealer
A reactive, water-based inorganic formulation that replaces an existing sealer or is introduced as a new treatment. The catalog lists 1 part concentrate to 10 parts water for rack plating. Barrel conditions differ by acid or alkaline line and initial make-up or replenishment. Refer to the latest TDS for the applicable dilution ratio.
Process overview: zinc plating → activation and chromate treatment → UP300-A in the third rinse → UP300-B sealer. For alkaline lines, review the addition of UP300AKL to the plating bath. Operating specifications depend on the plating bath, rack or barrel process, and initial make-up or replenishment stage.
Use the latest TDS and agreed line operating specification for dosage, bath concentration and dilution ratios. Calculator defaults are inputs for cost estimation.
