Specifications for Surface Preparation and Application of Coraflon Coatings

Last modified: 12/27/2007

Substrate

Surface Preparation

Primer Application

Application

 

Aluminum

Milled, Anodized, Bare

 

Solvent clean, per SSPC SP-1, substrate to remove any contamination that may be present.

 

Abrade substrate to obtain a surface profile. Depending on the alloy, and substrate softness, this can be accomplished a variety of ways such as: hand sanding, Scotch-Brite pads, Hand Tool Cleaning per SSPC SP-2. 

 

Prior to coating, Solvent wipe substrate to remove dust and residual contamination

 

Apply Coraflon™ ADS Wash Primer ADS225/ADS 226 @ 0.3-0.5 Mils dry film thickness (DFT).  Allow the primer to cure a minimum of 2 hours prior to top coating.

 

Intermediate Application

Apply one coat of Coraflon™ ADS High Build Epoxy Primer/Intermediate ADS 538/ADS539 at 3.0 –5.0 mils DFT. 

 

Apply one coat Coraflon™ ADS topcoat per instructions on the respective products technical data bulletin.

 

Coraflon™ ADS Metallic coatings require a clear finish coat.  The clear coat protects the aluminum pigmentation from ultraviolet degradation.  Allow metallic topcoat to dry 4 hours minimum @ 77° F.

Full cure will be achieved in three to five days

 

 

 

 

New Galvanized Steel

 

Abrasive blast per SSPC SP-7 / NACE 4 "Brush-Off Blasting" removing a passivator that may be present and obtaining a surface profile of 1.0 to 2.0 mils.

Insure that a passivator is not present.

 

Apply Coraflon™ ADS Wash Primer ADS225/ADS 226 @ 0.3-0.5 Mils dry film thickness (DFT).  Allow the primer to cure a minimum of 2 hours prior to top coating.

 

Intermediate Application

Apply one coat of Coraflon™ ADS High Build Epoxy Primer/Intermediate ADS

 

Weathered Galvanized Steel

 

Power tool clean, per SSPC SP-3, or more recommended, abrasive blast per SSPC SP-7 / NACE 4 "Brush-Off Blast Cleaning", with a surface profile of 1.0 to 2.0 mils.

 

One coat of Coraflon™ ADS High Build Epoxy Primer/Intermediate ADS538/ADS539 at 3.0 –5.0 mils DFT. 

 

Carbon Steel

 

Prepare surface per SSPC SP-6 "commercial blast" minimum.  Surface profile shall be 1.5 – 2.0mils.

 

Apply one coat of Coraflon™ ADS High Build Epoxy Primer/Intermediate ADS538/ADS539 @ 4.0-6.0 Mils DFT. 

 

Inorganic Zinc Coatings

 

Solvent clean, per SSPC SP-1, or power wash surface to remove any contamination from the substrate that may be present

 

Apply one coat of Coraflon™ ADS High Build Epoxy Primer/Intermediate ADS538/ADS539 @ 2.0-4.0 Mils DFT.  A mist coat may be necessary to eliminate bubbling.  Allow the primer to cure 18-24 hours before top coating.

 

 

 

Megaflon MC-Series Coatings

 

Silicone Polyester Coatings

 

Solvent clean, per SSPC SP-1, or power wash surface to remove any contamination from the substrate that may be present.

 

Abrade substrate to remove gloss and to obtain a surface profile for adhesion of the MS-Series Megaflon™ or Coraflon™ ADS.  This can be accomplished by use of a Scotch Brite pad or equal.  Care should be taken not to abrade the surface too aggressively as surface defects may show when coated

 

Prior to coating, solvent wipe substrate to remove dust and residual contamination.

 

No Primer Necessary

 

Apply one coat Coraflon™ ADS topcoat per instructions on the respective products technical data bulletin.

 

Coraflon™ ADS Metallic coatings require a clear finish coat.  The clear coat protects the aluminum pigmentation from ultraviolet degradation.  Allow metallic topcoat to dry 4 hours minimum @ 77° F.

Full cure will be achieved in three to five days

 

 

PVDF Kynar Resin & Duranar® Coated Surfaces

 

Solvent clean, per SSPC SP-1, substrate to remove any contamination that may be present.

 

Abrade substrate to remove gloss and to obtain a minimum surface profile of 1.0 mil for adhesion of the Megaflon™ MS / Coraflon™ ADS.  This can be accomplished by hand sanding with 80 – 120 grit sandpaper or equal.  Care should be taken not to abrade the surface too aggressively as surface defects may be visible when coated.

 

Prior to coating, Solvent wipe substrate to remove dust and residual contamination

 

 

Apply one coat of Coraflon™ ADS PVDF Bonding ADS511/ADS512 @ 2.0 – 5.0 mils DFT.  Allow primer to cure 48 hours minimum @ 72° F before applying topcoat.
