GENERAL
It is a two component coal tar epoxy coating, black in color, used to protect steel, concrete structures, timber in corrosive environments.
SALIENT FEATURES
- The cured coating is flexible and affords excellent resistance to impact, thermal shock and abrasion.
- It cures to a hard, smooth film, having exceptional resistance to immersion in salt water, or in alkaline or neutral solutions
- It can be applied to steel, concrete and timber.
APPLICATIONS
Recommended for coating of tanks, piping, sheet piling, mild steel liner to piles, foundation walls and sumps. Also suitable for concrete and steel surfaces in sewage treatment plants, paper mills and chemical plants. Excellent for below grade surfaces.
INSTRUCTIONS FOR USE
Surface Preparation
Concrete - For best results on concrete, light sandblasting or other suitable surface preparation is recommended. Oil free compressed air is used to remove residual dust.
Steel
Steel surfaces, which are to receive coal tar epoxy, should be prepared by abrasive blasting or by applying a de-rusting solution of RUSTICIDE to get commercial gray metal standard. If prepared surfaces are contaminated by rust or other contaminants, they must be recleaned.
Mixing
Mix both the components Part A and Part B in the proportion of ( 1: 1 by weight) with slow speed stirrer (300 to 600 rpm) for two - three minutes.
APPLICATION
For best results, apply two coats of COALTAR EPOXY by brush, roller or spray. If spray applied, airless-type equipment is preferred. First coat should be applied at a thickness of approximately 10 mils and allowed to cure tack-free. Second coat should be applied at a thickness of approximately 10 mils within 72 hours.
COVERAGE
1 kg of COALTAR EPOXY mix covers approximately 50 to 60 sq.ft. per coat. May vary on the nature of surface and number of coats.
PRECAUTION
DANGER! FLAMMABLE! Keep away from heat, sparks and flame. Avoid breathing vapor. Use with forced air ventilation in confined areas. Avoid contact of resin or hardener with the skin or eyes. In case of skin contact, remove with soap and water or waterless hand cleaner. In case of eye contact, flush immediately with plenty of water and consult a physician. Do not take internally.
