TWO COMPONENT EPOXY BASED ABRASION AND CORROSION RESISTANT PROTECTIVE COATING

Hind ERS 21 PC is a two component protective coating based on epoxy resin system comprising of Component A (Resin) and Component B (Hardener). It is designed specially to protect steel, concrete structures and all other metallic substrates influenced by seawater splash, severe saline and highly corrosive environment. It is an excellent abrasion cum protective coating system.

Description

USES

HIND ERS 21 PC is recommended as a coating for protection against abrasion and corrosion protection for Tanks & Reservoirs (Concrete &Steel), Pipelines (Concrete & Steel), Chemical Plants, Dockyards, Water Treatment Plants, Concrete & Steel surfaces in sewage treatment plant, Crude oil storage tanks, Underground Structures (Foundation walls & sump pits), Paper Mills, Dams, Barrages gates, Hydel equipments and Penstocks.

ADVANTAGES

  • Highly Corrosion & Abrasion Resistant in saline and sea-water environment.
  • Cured material turns to a hard coating moderately flexible in nature.
  • Like all epoxy resin system it has high chemical resistance.
  • Reduce thermal expansion co efficient thus improves thermal conductivity.

SURFACE PREPARATION

Concrete

Before application surface preparation is important, surface should be cleaned, dry, free from loose particles, oil, grease or other foreign materials by water jetting or any other suitable methods. Compressed air is used to remove the dust completely. The coating to be done on absolutely dry surface free from any entrapped moisture in the concrete.

Steel

Steel surface over which coating is to be done should be thoroughly sand blasted or mechanically cleaned to a shinning finish. If prepared surface gets contaminated, it has to be re-blasted to get a absolutely clean surface and coating applied.

Mixing

The coating system of HIND ERS 21PC is thixotropic in nature, it has to be properly stirred before application. Mix 1 part by wt of component B with 2 parts by wt of component A i.e. Mixing Ratio = Component A: Component B = 2:1 (by wt). Mix at least 5 minutes to uniform color without any steak using a drill and paddle mixed (speed 200 RPM) so as to avoid any entrapped air. Comp B is to be poured in Comp A and stirred gently.

APPLICATION

HIND ERS 21PC can be applied by brush or roller. Normally two coats are recommended. The first coat to be allowed to air cure to become tack free before the second coat is applied.

Cleaning: Clean all tools & equipment immediately after use with, Xylene, Toluene or suitable solvent.
