Category：Application industries, powder Coating | Brand：MT
Introduction
Valves and pipes powder coating is an epoxy resin and curing-agent system with strong mechanical performance, a clean film surface, high corrosion resistance and good electrical insulation. It is supplied in standard-cure and low-temperature-cure versions, in a range of gloss levels and colours, and as a hot-melt epoxy variant for demanding pipe and valve duty.
Features & Applications
Excellent mechanical properties (impact, hardness, toughness, adhesion), good surface finish, strong corrosion resistance and good insulation. Used on mechanical and electrical equipment, safes, industrial equipment, pipelines, steel wire and chemical-laboratory equipment.
Specific gravity 1.1–1.8 g/cm³. Standard-cure and low-temperature-cure grades; various gloss and colour options; hot-melt epoxy available.
