EPOXY HIGH SOLIDS COATING FOR ANTI-CORROSION－EP-988

Specification Data

Type

The high solids coating based on epoxy resin with anti-corrosive pigment and mica powder.

Uses

Used for ship, bridges, tanks, pipelines, petrochemical plants and steel structures.

Characteristics

˙Tough and hard film, excellent abrasion resistance.

˙Excellent anti-corrosion and water resistance.

˙Excellent resistance to oils and chemicals.

˙Use green anticorrosion pigment in formula, both excellent inhibitory and hiding performance of corrosive protection for steel.

˙Can be applied to variety types of coating, or be coated a variety types of coating, for the best maintenance coating.

˙When primer use PU700 and topcoat use high weather resistant paint, the anti-corrosion

performance is especially excellent.

General

Remove dirt, dust, oil and all other contaminants that could interfere with adhesion of the coating.

Surfaces must be clean and dry. Moisture, grease, sludge, dust, corrosive salt must be thoroughly cleaned from substrate.

Primed Surfaces

Areas of

Breakdown and

Damage

Surface preparation standards can use SSPC-SP10 or Sa2 1/2 (ISO 8501-1:2007).

EP-988 should always be applied over a recommended anti-corrosive coating scheme. The primer surface should be dry and free from all contamination and EP-988 must be applied within the overcoating intervals specified (consult the relevant product data sheet).

It should be prepared to the specified standard (Sa2 1/2 (ISO 8501-1:2007) or SSPC-SP6, Abrasive Blasting or SSPC-SP11, Power Tool Cleaning) and patch primed prior to the application of EP-988.

Mixing

Mixing Ratio

Pot life

Mix base and hardener according to the mixing ratio and stir thoroughly.

Use Epoxy Thinner (SP-12) to thin up 0-5%.

Base : Hardener = 79.3 : 20.7 ( by weight )

Avoid applying the paint in rainy weather or the relative humidity exceed 85%, particularly, a wet surface must be thoroughly dried. All equipment must be cleaned immediately after use. To increase or decrease the usage of thinner depending on the temperature of the coated surface, the temperature decreased may have to add more amount of thinner

Pump ratio 45:1 or greater
