Automotive Plastic Primer Spray – Adhesion Promoter | LIHA Aerosols 500ml

Improve paint adhesion on plastic automotive parts with LIHA Aerosols Automotive Plastic Primer Spray. Specially designed as an adhesion-promoting base layer, it helps prepare properly cleaned plastic surfaces before applying primer, basecoat or topcoat.

Automotive plastics can be difficult to paint directly because many surfaces have low surface energy and poor paint grip. LIHA Plastic Primer creates an intermediate adhesion layer that helps the subsequent coating system bond more effectively to compatible plastic components.

The ready-to-use 500ml aerosol format makes it convenient for body shops, repainting work, bumper repairs, motorcycle parts and DIY refinishing.

Surface Preparation

Correct preparation is essential when painting plastic.

1. Clean Thoroughly

Remove:

• Dirt

• Grease

• Oil

• Silicone

• Wax

• Polish residue

• Release agents

• Surface contamination

Use a suitable plastic-safe cleaner or degreaser.

2. Prepare the Surface

Lightly abrade the surface if required for the specific plastic and coating system.

Remove all sanding dust before application.

The surface must be completely clean and dry.

3. Check Compatibility

Different automotive parts can be manufactured from different types of plastic.

Always perform a small test application before coating the complete part.

Directions for Use

1. Shake Well

Shake the aerosol vigorously for approximately 2–3 minutes before use.

Continue shaking occasionally during application.

2. Test Spray

Test the product on a hidden or spare area to confirm adhesion, spray pattern and substrate compatibility.

3. Apply a Thin Coat

Hold the can approximately 20–30 cm (8–12 inches) from the surface.

Apply a thin and uniform adhesion-promoting coat using smooth overlapping passes.

Avoid excessive film build.

4. Allow to Flash

Allow the plastic primer to flash and dry sufficiently before applying the next compatible coating.

5. Apply the Paint System

Depending on the repair process, follow with a compatible:

• Automotive primer

• Basecoat

• Colour coat

• Clear coat system

Follow the requirements of the subsequent coating system.

Important: Apply Thinly

Plastic adhesion promoter is designed to create a bonding layer and should not normally be applied like a heavy-filling primer.

Excessive application can reduce coating performance.

Use controlled, light and even passes.

Suitable For

LIHA Automotive Plastic Primer can be used on many properly prepared automotive plastic parts, subject to compatibility testing.

Common examples include:

• PP-type bumper components

• ABS components

• Automotive trim plastics

• Plastic fairings

• Moulded automotive accessories

Because plastic formulations vary, always test compatibility before complete application.

Important Application Notes

• Clean plastic thoroughly before application

• Remove silicone, wax and mould-release residue

• Do not apply over contaminated surfaces

• Apply thin, even coats

• Avoid heavy wet application

• Use in a well-ventilated area

• Allow sufficient flash time before topcoating

• Test compatibility on unknown plastic substrates

• Follow with compatible automotive coating products

Recommended Painting System

For a typical automotive plastic repair:

Clean Plastic → Prepare Surface → LIHA Plastic Primer → Compatible Primer/Basecoat → Colour Coat → Clear Coat

The exact coating process may vary depending on the plastic type, surface condition and repair requirement.

Benefits for Automotive Refinishing

Using a dedicated plastic adhesion promoter before painting helps create a more reliable coating system on plastic parts that would otherwise be difficult to paint directly.

It is especially useful for:

✔ Replacement bumpers
✔ Repaired bumper sections
✔ Plastic trim repainting
✔ Motorcycle bodywork
✔ Automotive accessory refinishing
✔ Colour-change projects
✔ Touch-up and restoration work
