Overview
NIPPON EA9 RED OXIDE PRIMER is a two-pack, low gloss Amine Adduct Epoxy Primer designed for use as a high performance primer for many types of surfaces i.e. aluminium, galvanizing, steelwork, concrete, GRP and phenolic sheeting for corrosion environment. It have been extensively used for long term corrosion protection of both ferrous and non-ferrous surfaces within the civil engineering and building industry, and as lining system for potable water, chemical and fuel storage tanks, palm oil derivatives and vegetable oil.
Physical Characteristics of Paint:
Colour: Red Oxide
Finish: Low Gloss
Specific Gravity: 1.25 ± 0.05 (for Mixture of Base & Hardener)
Solid Content:38 ± 2 by volume (for Mixture of Base & Hardener)
Abrasion :Good resistance to abrasion and mechanical damage
Adhesion :Excellent on correctly prepared surfaces
Chemical Resistance: The fully cured coating offers outstanding resistance to aqueous solutions and a wide range of industrial chemicals, mild acids, crude oils, Jet fuel, fats, cutting oils, fruit juices, etc.
Weathering: Not recommended for direct exposure to sunlight. It is always used as a base coat in conjunction with a Nippon Polyurethane finish coat.
Temperature: Dry service temperature range up to 100°C
Recommendation for Use:
Surface Preparation
Mild Steel Surfaces
For optimum performance, abrasive blasting in accordance to SA-2.5 Standard is desirable. It is important that the standard should be maintained until the paint is applied on. If the steel changes colour or rust bloom begins to form, it will be necessary to reblast the steel. The surface must be dry and free from any abrasive residues, dirt, oil and grease and other contaminants prior to painting.
Galvanised Steel Surface
New galvanised surface requires to be degreased in accordance to SSPC-SP1. For old galvanised surface, it must be abraded to remove corrosion deposits. Shop-prime with a suitable etching primer e.g. NIPPON VINILEX 120 ACTIVE PRIMER. All surfaces must be dry and fee from oil and grease prior to painting.
Aluminium and Stainless Steel Surface
For optimum performance, the surface must be lightly abrasive blasted. If blasting is not possible, abrade with 120 grade paper, clean and dry prior to painting. Shop-prime with a suitable etching primer e.g. NIPPON VINILEX 120 ACTIVE PRIMER. All surfaces must be dry and fee from oil and grease prior to painting.
Recommended No. of Coats: 1 - 2 coats
Recommended Film Thickness per coat:
50 microns for dry film
131 microns for wet film
Application Data:
Application Methods: Brush, roller, compressed air spray and airless spray
Thinning :
Roller & Brush: 10% maximum
Air Spray: 25% maximum
Airless Spray: 5% maximum
Mixing Ratio: 9 parts by volume of NIPPON EA9 RED OXIDE PRIMER (BASE) to 1 part by volume of NIPPON EA9 HARDENER.
Stir the content of the BASE component, continue stirring and gradually add the total content of the HARDENER component, continue stirring until a homogeneous mix is obtained. Dilution should be done after the addition of hardener.
Pot Life at 25oC to 30oC: 6 - 7 hours after mixing, depending on prevailing temperature
Thinner: NIPPON SA 65 THINNER
Cleaning Solvent: NIPPON SA 65 THINNER
Note: All equipment should be cleaned IMMEDIATELY with Thinner after use. For thinning, substitute thinners other than those approved or supplied by Nippon Paint may adversely affect the product performance and void product warranty whether expressed or implied.
Drying Time at 25oC to 30oC:
Dry to touch: 30 minutes
Dry to handle: 4 - 5 hours
Dry to overcoat: Minimum 16 hours. Maximum 15 days. Recoating of a fully cured NIPPON EA9 RED OXIDE PRIMER may results in poor adhesion to the previous coats and sanding is a must to avoid this.
Curing time at 25°C to 30°C: 5 - 7 days
Note: Drying time will become remarkable under low temperature. Overcoating the previous coat of NIPPON EA9 RED OXIDE PRIMER should be done within 6 - 7 days but preferably as soon as possible after it has been allowed 16 hours drying or else, it is desirable to roughen it by dry sanding with sandpaper before it is overcoated. This is to ensure proper intercoat adhesion. Exposure of the paint film to water, chemical and abrasion should be avoided as far as possible before full cure of the coating. When chalking occurs, chalks should be removed by water washing. Allow the surface to dry thoroughly prior to overcoating.
Standard Packing:
5 Liters (4.5 Liters BASE & 0.5 Liter HARDENER)
