Features

Versatile

 N/A Enhances adhesion to difficult-to-bond elastomers, increasing the adhesion of coatings, double-sided tape and adhesives.

Easy to Apply

 N/A Low viscosity allows for easy application, no dilution necessary.

Applications

Surface Preparation

 N/A Wipe surface to be primed with a suitable solvent, or wash with detergent and water, then rinse.

Mixing

 N/A No mixing is required before or during use.

Applying

 N/A Apply Chemlok® 459X primer by brush, dip or spray method. For optimum adhesion, the dry film thickness of Chemlok® 459X primer should be approximately 2.5 micron (0.1 mil).

Cleanup

 N/A Use a dry cloth wipe to remove wet primer. Remove dried primer with xylene or a ketone-type solvent.

Storage and Handling

Storage and Handling

 N/A Shelf life is six months from date of shipment when stored at 21-27 ºC (70-80 ºF) in original, unopened container.
