| | EPX 02 zp is a two-component anti-rust epoxy primer containing zinc phosphate.
| | |
| | As a rust inhibitor primer on metal surfaces. Typical uses with a suitable topcoat are for structural steel, steel pipes and tanks, telecommunication towers, steel sheds, paper mills, oil refineries, power plants, chemical process, waste treatment plants and in all marine steel structures exposed to hard weather conditions and high humidity. Also, EPX02 ZP is an ideal primer for autorepair, engines and vehicles…etc. | | |
| • Excellent adhesion on steel surfaces.
• Excellent corrosion resistance (contains zinc phosphate).
• Can be coated with a wide range of topcoats (epoxy, urethane, alkyd, latex).
• Can be used for immersion or non-immersion service with suitable topcoat.
• Resists continuos temperature service up to 140°C "non immersion service".
| | |
| | • Method of Application : | Airless or conventional spray, brush or roller. | | • Mixing Ratio : | (by volume) : 4 to 1 (A to B). | | • Mixing : | The individual components should be thoroughly stirred before the two are mixed together. Combine components (A & B) in supplied proportions and mix thoroughly using a slow speed mixer for at least 3 minutes to achieve uniform consistency; “DO NOT USE HIGH SPEED MIXER”. Never mix more material than can be used within potlife. Material that has begun to set must be discarded. | | • Pot life : | (20°C) : 24 hours (higher temperatures will shorten the potlife sharply). | | • Thinner / Cleaner : | S405 “Known as Epoxsol” is uesd for thinning or cleaning. Mixing ratio with thinner depends mainly on temperature and on method of application.
For example: At 20°C airless spray application will need no dilution.
Conventional spray will need approx 25% by volume thinner S405. Other methods of application will need approx 15% by volume thinner S405. The higher the temperature the less the needed dilution. Due to potlife limitations, clean all mixing and applying tools by thinner S405 immediately after application is completed.
| | • Note : | • When recoating, a special attention should be given toward drying times “minimum & maximum recoating time”. Any delay in applying interval coats may request sanding the surface of the previous coat to insure good adhesion.
• The reaction between the epoxy and its curing agent (A & B) can not be guaranteed unless a temperature of at least 10°C is maintained for the mixture and the substrate until complete curing. Temperature of substrate should be at least 3°C above dew point to avoid moisture condensation during application.
• Coated surfaces by EPX02 ZP should not be exposed to water, chemicals, or mechanical stresses before it is fully cured.

| | • Color : | Off-white | | • Gloss : | Flat (ASTM-D523). | | • Volume Solids : | 59.4 % (ASTM-D2697). | | • Flexibility : | Good | | • Recommended film thickness : | 50-100 microns “dry” | | • Theoretical spreading rate : | 11.9 m²/L at 50 microns "dry" | | • Water resistance : | Excellent | | • Abrasian Resistance : | Excellent | | • Chemical Resistance : | Good (A separate leaflet CHR01 is available) | | • Solvent Resistance : | Fair (A separate leaflet CHR01 is available) | | • Number of Coats : | 1-2 | | • Specific Gravity (mixed) : | 1.39 kg/L (ASTM-D1475). | | • Packaging : | Component A “base” : 3.6 or 0.9 L in metal can.
Component B “drier: CAT10” : 0.9 or 0.225 L in metal can.

| Proper surface preparation is essential to ensure coating success, performance, and longevity. In general, all surfaces must be clean, dry, undamaged, and free of contaminants prior to application.
STEEL
•Non-immersed surfaces: Abrasive blast to Sa2 in accordance with ISO 8501-1, achieving a surface profile of 50–100 µm.
•Immersed surfaces: Abrasive blast to Sa2½ (near-white metal finish) as per ISO 8501-1, with a surface profile of 50–100 µm.
Aged or previously coated steel: Abrasive blast to Sa3 according to ISO 8501-1, ensuring a surface profile of 50–100 µm.
Additional Instructions :
• Thoroughly remove all abrasive residues and dust from the prepared surface.
• Eliminate oil, grease, wax, and similar contaminants using S405 thinner (Epoxsol).
•Apply the coating system (EPX02 ZP) as soon as possible following surface preparation to prevent recontamination. Blasted steel must not be left exposed overnight.
•If immediate application of EPX02 ZP is not feasible, a thin layer of EPX02 primer is strongly recommended as a temporary protective coating.
• Prior to the application of EPX02 ZP over EPX02, ensure the primed surface is clean, completely dry, and free from oil, grease, or any other contaminants.

| | • Dry to Touch : | 1 hour (ASTM-D1640). | | • Dry to Handle : | 10 hours “minimum recoat time”. 24 hours “maximum recoat time” (ASTM-D1640). | | • Fully Cured : | 7 days. | | • Note : | Drying times can be affected by many factors such as temperature, ventilation and coat thickness. Higher temperatures will shorten the drying times. |
| | |
| • Epoxy system, in general, especially component B, has to be kept in a cool and well ventilated place, protected from heat and direct sunlight. EPX02 ZP is classified as being highly flammable material.
• Shelf life is two years from packing date in unopened original containers at 10 to 40°C. Containers should be kept tightly closed.
Safety:
• Well ventilated conditions should be provided during application.
• Do not breathe or inhale mist.
• Wear air-mask and avoid skin or eye contact.
