2K Epoxy Primer Kit
Professional two-component epoxy primer designed for automotive refinishing and surface preparation. It delivers excellent adhesion, corrosion protection and fast drying for both ferrous and non-ferrous substrates.
ProXL Generation20
What It Does
ProXL 2K Epoxy Primer acts as a sealing and protective layer between bare metal and topcoats:
✔ Seals bare metal against corrosion
✔ Improves cohesion of subsequent body fillers
✔ Provides a uniform base for finishing coats
✔ Enhances paint durability in service environments
✔ Supports wet-on-wet application on repairs
Key Benefits
• Outstanding adhesion to steel, galvanised steel and aluminium.
• Fast drying — overcoat wet-on-wet after ~30 minutes at 20°C.
• Easy to sand, either wet or dry.
• Excellent corrosion & moisture protection on prepared surfaces.
• Solvent and chemical resistant primer base.
Technical Application Info
• Mix ratio: 4 parts epoxy primer : 1 part hardener (by volume) — standard for 2K epoxy systems.
• Thinner: Add 10–40% thinner (depending on application method).
• Application: Apply by spray gun in 2–3 medium coats.
• Overcoating: Ready for next layer wet-on-wet after ~30 minutes at 20 °C.
• Sanding: Easy sanding wet or dry — ideal before further primer or topcoat.
• Coverage: ~10 m² per litre at 50 µm dry film thickness.
(Actual coverage may vary with technique and surface profile.)
Suitable For
• Bare metal substrates: steel, galvanised steel, aluminium.
• Body repair preparation: before body filler and topcoat.
• Professional refinishing environments: bodyshops, light repair centres.
• Moisture-prone areas: offers protection where corrosion risk exists.
FAQ - Frequently Asked Questions – Epoxy Primer
⸻
1. Can epoxy primer be applied directly to bare metal?
Yes. Epoxy primer is specifically designed for direct application to bare steel, galvanised steel and aluminium, providing excellent adhesion and corrosion protection.
⸻
2. Do I need to use an etch primer before epoxy primer?
No. Epoxy primer replaces etch primer in most professional refinishing systems and offers superior sealing and corrosion resistance.
⸻
3. Can filler be applied over epoxy primer?
Yes. Body filler can be applied over epoxy primer once it has flashed off or lightly sanded, depending on the repair process.
⸻
4. Can epoxy primer be used wet-on-wet?
Yes. This epoxy primer supports wet-on-wet application, allowing topcoats or further primers to be applied without sanding after the correct flash-off time.
⸻
5. Is epoxy primer sandable?
Yes. After full cure, epoxy primer can be wet or dry sanded, making it suitable as both a sealing and surfacing base.
⸻
6. How long does epoxy primer take to dry?
At 20°C, epoxy primer typically:
• Is ready for wet-on-wet overcoating after approx. 30 minutes
• Can be sanded after full cure
Drying times may vary with temperature and film thickness.
⸻
7. What is the correct mixing ratio?
The standard mixing ratio is:
4 parts epoxy primer : 1 part hardener
Reducer can be added 10–40% if required.
⸻
8. Can epoxy primer be applied over existing paint?
Yes, provided the existing paint is clean, sound and correctly sanded. Epoxy primer works well as a sealer over old paint systems.
⸻
9. Is epoxy primer waterproof?
Epoxy primer offers excellent moisture resistance and is commonly used to seal bare metal against humidity and corrosion.
⸻
10. Can epoxy primer be left exposed before topcoating?
Epoxy primer can be left exposed for a limited time, but for best results it should be topcoated within the recommended window to ensure optimal adhesion.
⸻
11. Can epoxy primer be used for SMART repair?
Yes. Epoxy primer is widely used in SMART repair and spot repair due to its fast flash-off and strong adhesion.
⸻
12. Is epoxy primer suitable for classic car restoration?
Yes. Epoxy primer is highly recommended for restorations because of its corrosion protection and long-term durability.
⸻
13. Can epoxy primer be sprayed with a standard spray gun?
Yes. It can be applied using conventional HVLP or compliant spray guns with the correct setup and thinning.
⸻
14. Does epoxy primer need a clear coat?
Epoxy primer itself is not a topcoat and must be overcoated with a suitable primer, basecoat and clear coat system.
⸻
15. Is epoxy primer suitable for aluminium panels?
Yes. When properly prepared, epoxy primer offers excellent adhesion to aluminium and prevents oxidation.
