Coroguard SBP 100 : Coal Tar Epoxy  

 

Product Description :

 

Coroguard SBP - 100 is high solids, high build polyamide cured coal tar epoxy coating. The outstanding water resistance of coal tar, together with the chemical and solvent resistance, toughness and adhesion of epoxy resin, combine to give excellent overall corrosion protection.

 
Features and Benefits :
 

Easy to apply and can be applied via airless spray, conventional spray, brush or roller.

Can be used as primer, intermediate or finish coat.

Suitable for varied end application i.e. ideal for heavy industrial, chemical, marine, splash and spillage, fresh water, sea water or chemical immersion.

Provides desired film build up to 125 microns per coat.

Excellent resistance to acids, alkalis, water, salts, oils, petroleum solvents.

Has excellent impermeability to water and chemical vapours.

Has excellent adhesion property over a steel and concrete when applied without primer. 

Tough hard film that serves as single protective coat in severe corrosive conditions. (Topcoats are recommended for maximum protection.)

Provides long-term protection and is economical.

  Surface Preparation :  
     
 

SteelThe surface should be blast cleaned to SSPC-SP 10-63T or NACE No. 2 i.e. loose rust and scales, dirt, grease, oil, paint, wax, weak oxide films and other contaminants should be removed. Blast cleaning to SSPC-SP 5-63 or NACE No. 1 is recommended where heavy corrosive conditions exist or coating is required to be immersed. That means a surface with a grey metallic colour, slightly roughened to form a suitable anchor pattern for coatings. This surface is free of all oil, grease, dirt, mill scale, rust, corrosion products, oxides, paint and other foreign matter. In absence of blast cleaning, prepare the metal surface by wire brushing, sanding, grinding, scrapping or chipping with hand or power tools. Remove all the contaminants. Apply two coats of Coroguard SBP - 100. It can be overcoated with Durapoxy 200 Epoxy Enamel, Anuthane Enamel Polyurethane or Monocoat Enamel Polyurethane.

Non-ferrous Metals - Remove dirt, dust, oil, old paint etc. Degrease the surface with degreasing solvents like xylene or tri-chloroethylene. Apply one coat of Anuprime – 291 Wash Primer for obtaining maximum adhesion. Apply one or two coats of Coroguard SBP - 100.

ConcreteThe concrete surfaces must be thoroughly cleaned and free from pits, pockets and holes. Etch the surface with 10-15% muriatic acid diluted in water. Allow the acid solution to remain on the surface for 10 to 15 minutes or until the bubbling stops. Thoroughly rinse the surface to remove all traces of acid. Allow the surface to dry completely before painting.

Notes :-  
 
     
 
Brushes and spray equipments should be cleaned with Anusol - ETP Epoxy Thinner.
The contents should be stirred thoroughly prior to use.

After mixing Base and Hardener in recommended proportions, allow for 30 minutes induction period or sweat-in-time (maturing) before application.

When overcoating the weathered or aged Coroguard SBP - 100 ensure that the coating is fully free from all contamination such as oil, dust, grease, stains etc.

This coating should always be thinned with Anusol - ETP Epoxy Thinner. The use of alternative thinners can severely inhibit the curing mechanism of the coating.
