WASH PRIMER CF CONVERTER

What it is and why choose it

Awlgrip WASH PRIMER CF CONVERTER (OD3300) is the converter component of the chromate-free Wash Primer CF etch primer system. Based on Controlled Fusion (CF) technology, it reacts chemically with the base component to create a tightly fused intercoat layer that delivers excellent adhesion to metal substrates, extended re-coat windows and eliminates the need for sanding between coats. The CF system removes the requirement for high-hazard chromate chemicals while maintaining high performance for professional coating applications.

Main features

• Chromate-free etch primer system when combined with Wash Primer CF base (D6600).
• Controlled Fusion (CF) technology providing a unique chemical reaction that ensures strong adhesion between the CF layer and subsequent coats.
• No sanding required before applying the next coat within the recommended re-coat window.
• Extended re-coat time: may be recoated without sanding for up to 6 months (at 25 °C and 50% RH).
• Designed for metal substrates: suitable for aluminium, anodised aluminium and stainless steel (as part of the Wash Primer CF system).
• Fast drying: dust-free in about 30 minutes and hard dry in about 2 hours at 25 °C / 50% RH when used in the system.
• High VOC product supplied at maximum allowable VOC; no reduction recommended.
• Compatible topcoats: can be overcoated with 545 Epoxy Primer and Awlgrip topcoats; not suitable under Awlgrip Fairing Compounds.

Applications and use cases

• Professional metal priming on aluminium, anodised aluminium and stainless steel surfaces where a thin, high-adhesion etch primer is required.
• Marine and industrial topside systems as part of multi-coat schemes using 545 Epoxy Primer and Awlgrip topcoats.
• Fast-drying topcoat systems where quick handling and extended re-coat times are needed without sanding between coats.
• Build systems that require increased film thickness and hiding of surface imperfections when followed by epoxy primers and Awlgrip finishing systems.
• Situations where chromate-containing etch primers are not permitted but high performance adhesion to metal is still required.

FAQ

1. 1. What is WASH PRIMER CF CONVERTER used for?

   It is the converter component (OD3300 / D3300) of the Wash Primer CF chromate-free etch primer system. Mixed 1:1 by volume with the D6600 yellow base, it activates the Controlled Fusion technology that provides adhesion and extended re-coat times.

2. 2. On which substrates can the Wash Primer CF system be applied?

   The system is suitable for aluminium, anodised aluminium and stainless steel. It is not suitable for wooden or plastic surfaces.

3. 3. Do I need to sand between coats when using this primer system?

   Within the specified re-coat window, sanding is not required before applying the next coat. The system is designed to be recoated without sanding for up to 6 months at 25 °C and 50% RH, provided the surface is clean.

4. 4. What is the mixing ratio of base to converter?

   The mixing ratio is 1 part Wash Primer CF base (D6600) to 1 part WASH PRIMER CF CONVERTER (D3300) by volume.

5. 5. Which topcoats can be used over the Wash Primer CF system?

   The primer can be overcoated with 545 Epoxy Primer and Awlgrip topcoats (including Awlgrip, Awlcraft 2000, Awlgrip HS and Awlcraft SE topcoats). It is not suitable for use under Awlgrip Fairing Compounds.

6. 6. How long should I wait before putting the coated surface into service?

   Although the build system is touch dry after 24 hours at 25 °C following topcoat application, no assembly, stacking, drilling or service should take place until 2 weeks at 25 °C or 3 weeks at 13 °C to allow the Controlled Fusion process to fully activate and through-dry.

7. 7. Do I need to thin the mixed product?

   No. Reduction is not recommended, as the material is supplied at the maximum allowable VOC.

8. 8. How should I clean my equipment after use?

   Equipment can be cleaned using T0006 or T0002 reducers, or M.E.K.

9. 9. What is the pot life of the mixed primer?

   The pot life of the mixed Wash Primer CF (base plus converter) is approximately 8 hours at 25 °C and 50% RH.
