EPOXY PRIMER
EPOXY ENAMEL TOPCOAT
A two-component epoxy-polyamide based paint especially formulated for industrial use to produce hard, tough, and abrasion resistant film. It gives excellent
adhesion to various substrates and provides corrosion resistance to steel.
An ideal coating for areas where resistance to industrial conditions is desired. It is also suitable as an interior tank lining for potable water.

Surface Preparation
Surface preparation is an important step in application. Most problems are caused by improper surface preparations. Service life span and the service performance of
these products are directly related to the degree of surface preparation.
- Steel
Surfaces must be clean, dry and free of contamination such as wax, oils, grease, mill scale or rust. A minimum SSPC-SP2 Hand Tool Cleaning or SSPC-SP3
Power Tool Cleaning is recommended. However, an SSPC-SP6 Commercial Blast Cleaning will provide improved performance.
- Concrete
Sweep blast. Remove all contaminants such as dirt, laitance. Acid etched.
- Wood
Block down. Wipe with solvent containing cloth.

Application
Stir each component thoroughly before use. Mix to uniform consistency 3 parts of A (resin) with 1 part of B (catalyst). Mixed component should be applied within 6
hours.
Surface temperature must be at least 3°C above the dew point to prevent moisture condensation. Do not apply when the relative humidity exceeds 85%, to prevent
occurrence of condensation.
- Epoxy Putty
Add 4 kgs of calciumine to mixed component of Epoxy primer to come up with putty. Apply an even coat using pallete knife.
- Conventional Spray
Reduce if necessary with Epoxy Thinner up to 10% by volume of mixed paint to come up with good application viscosity. Use normal equipment suitable
for low viscosity paints.
- Brush/ Roller
Apply an even coat taking care to avoid runs and sags. Drying will be retarded if surface temperature is below 5°C and painting should be stopped until the
temperature rises. Care should be taken to avoid excess film build as this could lead to runs and retard drying. As drying involves solvent release, adequate
ventilation is essential. Do not vary recommended film thickness without the technical confirmation.
Safety Precautions
Thoroughly wash hands after application. Avoid contact with eyes and skin. Wear suitable protective clothing such as overalls, gloves and goggles. Use a dust mask/
particulate respirator or if applying by spray.
| Eyes |
: In the event of accidental splashes, flush eyes with warm water immediately. Then seek medical advice. |
| Skin |
: Wash skin thoroughly with soap and water. |
| Inhalation |
: Move to fresh air, loosen collar and keep patient rested. |
| Ingestion |
: In case of accidental ingestion, DO NOT INDUCE VOMITING. Obtain immediate medical attention. |
