400ML Acid Etch Primer – Aerosol

Etch Primer is a paint that is designed to physically bond itself to the substrate to which it is applied.

This is achieved by combining an acid with the paint so that the acid microscopically etches the surface of the substrate, thus forming a physical and chemical bond between the two.

Etch Primer - Directions for use

1. To achieve the best results always prepare the surface before painting. Make sure surfaces to be painted are clean, dry and free from rust, loose debris, grease, dust and silicon/wax. The use of a primer is recommended where applicable.

2. Use in a well-ventilated area.

3. To avoid overspray, protect surrounding area with masking tape and masking film or paper.

4. Always use the can at room temperature (21ºC approx.) and shake the can well for at least 2 minutes before use.

5. Spray in dry, windless conditions. Avoid spraying on excessively wet, cold or damp days. Test the spray on a small inconspicuous area first.

6. Hold can upright, approximately 15-25cm from the surface to be sprayed. Depress nozzle and spray with gentle back and forth motion. If the paint runs, increase the spray distance. If the paint appears dry and powdery, hold the can closer to the surface.

7. For best results apply several lighter coats, allowing 10-15 minutes between each coat. Shake can before use and in-between coats.

8. After use, turn the can upside down and spray briefly to clear nozzle of paint. If spray nozzle becomes blocked, remove it and soak in thinners.

Etch Primer: Enhancing Adhesion and Corrosion Resistance

Etch primer, also known as etching primer, is a type of primer used in automotive and industrial applications. It is designed to provide excellent adhesion to metal surfaces, particularly bare metal or surfaces that are difficult to bond with. Etch primers contain chemicals that create a chemical reaction with the metal, resulting in a surface that is more receptive to paint or other coatings.

Key Points about Etch Primer:

– Adhesion: Etch primers enhance the adhesion of subsequent layers of paint or coatings to the metal surface, ensuring a strong bond and reducing the chances of paint peeling or flaking.

– Corrosion Resistance: Etch primers often include corrosion inhibitors to protect the metal surface from rust and corrosion, making them ideal for use on bare metal or susceptible surfaces.

– Surface Preparation: Proper surface preparation is crucial for optimal results with etch primer. The metal surface should be clean, free from contaminants, and lightly sanded to ensure good adhesion.

– Application: Etch primers are typically applied in thin coats using a spray gun or brush. Achieving even and uniform coverage is important. After drying, the primer can be lightly sanded before applying the next layer of paint or topcoat.

– Compatibility: Etch primers are compatible with a wide range of paint systems, including solvent-based, water-based, and powder coatings. They are often used as a base coat for other primers or topcoats, but it’s essential to ensure compatibility with the subsequent coatings.

Keep in mind that specific product recommendations and application techniques may vary. Always refer to the manufacturer’s instructions and consult with professionals in the field for the best practices and advice when working with etch primers.
