Zip Chem - Sur Prep AP-1 Paint Adhesion Promoter, 11oz

• An adhesion promoter that can be used in place of scuff sanding between paint coats
• Improves adhesion
• Chemical reactivation of aircraft topcoats
• No need to “scuff” the surface

For Exterior Aircraft Surfaces

Used for :

• Reactivating paint surfaces for subsequent coats to be applied
• Increasing adhesion between basecoat and clearcoat coatings
• Application on radome polyurethane boots before topcoat application
• Enhancing paint adhesion used for stenciling to topcoats
• Spray as a thin, wet film to wet the substrate being sprayed.

The Sur-Prep® AP-1 aerosol can be used in conjunction with the Formit® extensions to provide targeted spray to areas that may be difficult to reach but need to be coated. Please refer to our Formit® technical datasheet for more information.

Perform application using standard paint application methods, such as HVLP guns, air-assisted airless spray guns, and electrostatic spray equipment.

Coverage is typically 600 to 1000 ft2 /gal (15 to 25 m2 /l), and flies away weight generally is less than 0.2 lb/1000 ft2 (1 kg/1000 m2).

When Sur-Prep® AP-1 is applied, the promoter forms a fine, whitish-gray powder and is easily detectible as it reduces the 60° surface gloss of the topcoat from 90 to below 10.

Once applied, the surface coated with Sur-Prep® AP-1 shall not be touched or disturbed before applying any subsequent coating.

Gloss reduction disappears upon application of the subsequent coats and does not affect the appearance in any way.
