NIPPON PAINT EA4 Epoxy Paint come with Hardener
NIPPON EA4 FINISH is a two-pack amine-adduct cured epoxy finish for use on steel and cement surfaces where chemical, oil and abrasion resistant coating is required. It is recommended for nonimmersion services. If it is to be applied over steel, it has to be used in combination with the appropriate primers as recommended below. If it is to be applied over concrete the surface should be acid-treated prior to application. NIPPON EA4 FINISH is also available in non-skid quality.
| Physical Characteristics of Paint | ||||
| Colour | As per colour card | |||
| Texture | High Gloss | |||
| Specific Gravity | 1.00 - 1.30, dependigng on colours | |||
| Solid Content | 51 ± 3% by volume (ASTM D2697 1973) | |||
| Abrasion | Good resistance to abrasion and mechanical damage | |||
| Adhesion | Excellent on correctly prepared and primed surfaces | |||
| Temperature | Dry service temperature range up to 100°C | |||
| Recommendation for Use | ||||
| Steel Surface Preparation | When used as a top coat within a NIPPON protective system, the steel surface would have been prepared in accordance with the recommendations provided within the product data sheet of the primer being used. This will normally be abrasive blast cleaning to minimum Sa 2½ ISO 8501-1:1988 or other equivalent international standard. The primed surface must be dry and free from any abrasive residues, dirt, oil and grease and other contaminants prior to painting. | |||
| Concrete Surface Preparation | The surface must be treated with about 5% sulphuric acid solution until effervescence has stopped. It should then be washed thoroughly with clean water and allowed to dry completely before coating with Nippon EA4 Finish. | |||
| Recommended No. of Coats | 1-3 coats | |||
| Recommended Film Thickness per Coat | 50 ~ 80 microns for dry film 100 ~ 160 microns for wet film | |||
| Theoretical Coverage at Receommended Film Thickness | 10.2 m²/litre (for dry film thickness of 50 microns) 6.4 m²/litre (for dry film thickness of 80 microns) Theoretical Coverage = Volume Solids (%) X 10 (m2 /litre) Dry Film Thickness (µ) | |||
| Practical Coverage (20% Loss Factor) | 8.2 m²/litre (for dry film thickness of 50 microns) 5.1m²/litre (for dry film thickness of 80 microns) | |||
| Application Methods | ||||
| Brush / Roller | Recommended for small areas and touch-up only. Good quality brushes and mohair/ short nap rollers should be used with full strokes. Avoid rebrushing. Thin up to 10% by volume of SA-65 Thinner for proper flow-out. Additional coats may be required to achieve minimum specified film thickness. | |||
| Spray | When airless spray is being used, excessive high tip spraying pressure should be avoided. The minimum pressure at the pump conducive with good atomisation should be used. | |||
| Guiding Data for Airless Spray | ||||
| Thinning | If necessary, add up to 5% thinner by volume for application by brush, roller and airless spray; about 10%-15% by volume for application by compressed air spray. | |||
| Mixing Ratio | 4 parts by volume of Nippon EA4 Finish (Base) to 1 part by volume of Nippon EA4 Finish (Hardener). Stir the content of the base component, continue stirring and gradually add the total contents of the hardener component, continue stirring until a homogeneous mix is obtained. | |||
| Pot Life at 25°C to 30°C | 6 - 8 hours after mixing | |||
| Thinner | SA-65 Thinner | |||
| Cleaning Solvent | SA-65 Thinner | |||
