Cold Spray Zinc vs Hot-Dip Galvanizing

A full, objective comparison of surface prep, application, salt-spray durability, cost and sustainability — and exactly when to choose each method.

Corrosivity categories C1 to CX, durability ranges, and what salt-spray test hours really mean when you compare anti-corrosion coatings.

HB, V-2, V-1, V-0 and 5VA/5VB explained — how the vertical burn test works, what UL94 V-0 really means, and why halogen-free matters.

ISO 8501-1 blast-cleaning grades from Sa 1 to Sa 3, what near-white-metal Sa 2.5 means, and why surface prep decides coating life.

VOC, safety, drying and performance compared — why waterborne systems are taking over, and when solvent-based still makes sense.

Thermal insulation classes under IEC 60085, why Class F (155°C) is the workhorse for fiberglass sleeves, and how coatings achieve it.
