Two-coat system: rust converter primer plus acid, alkali & chemical fume resistant topcoat for steel and industrial surfaces.
PREBOND-ARC is a practical two-coat protective coating system that combines a rust-converter-cum ceramic metal-bond primer base coat (PREBOND-CR) with a high-performance chemical and corrosion-resistant topcoat paint (PREBOND-220).
Both products are single-component, ready-to-use coatings based on silicone-modified polymer technology. The system is engineered for demanding chemical processing, infrastructure, automotive, commercial and marine applications, where surfaces are exposed to strong acid and alkali fumes, moisture, salt water, U/V radiation and weathering.
It is positioned as a practical alternative to selected conventional two-pack epoxy, enamel, PU and rubber-based protective paint systems, with no hardener and no mixing-ratio errors at site.

Rust Converter-cum Ceramic Metal Primer
PREBOND-CR is a high-performance, single-component, ready-to-use ceramic metal primer formulated with silicone-modified polymer technology and ultrafine nano-ceramic pigments. It is designed as a rust-converter-cum surface-tolerant intermediate primer for metal substrates and can be applied by conventional brush, roller or spray. The coating promotes strong adhesion between the substrate and subsequent topcoat while providing an additional protective barrier in corrosive environments.

PREBOND-ARC is a two-coat acid resistant paint system made of PREBOND-CR, a rust converter-cum ceramic metal primer, and PREBOND-220, an anti-corrosion chemical protective topcoat. Together they protect industrial surfaces from acid and alkali fumes, moisture, salt water and corrosion.
No. Both PREBOND-CR and PREBOND-220 are single-component, ready-to-use coatings, so there is no hardener and no mixing-ratio error at site.
Apply one coat of PREBOND-CR followed by one coat of PREBOND-220. Each coat is 60–75 µm DFT, giving about 120–150 µm overall for highly corrosive and highly acidic or alkaline environments.
It is used in chemical processing plants, hot dip galvanizing plants, fertilizer and pharma plants, steel and cement plants, distilleries, steel structures, tanks, pipelines, machinery and marine or coastal structures.
