LORD Chemlok ?? 459X primer is used to promote adhesion to thermoplastic elastomer (TPE), thermoplastic polyolefin (TPO) and EPDM rubber, and can be applied directly.
Chemlok 459X primer can be used with polyurethane and epoxy adhesives and various double-sided adhesive tapes. It can also be used as a primer to enhance the adhesion of polyurethane coatings to vulcanized EPDM rubber and other difficult-to-coat elastomers.
Features and benefits
Widely used: To strengthen the adhesion ability of difficult-to-adhere elastomers, to increase the adhesion ability of glue, double-sided tape and adhesive.
Easy to apply: Low viscosity makes it easy to apply without dilution.
Surface treatment: Wipe the surface to be primed with an appropriate solvent, or use detergent and water to clean the surface to be primed and then rinse.
Mixing: no need to mix before or during use
Application: Apply hemlock459X primer by brushing, dipping or spraying. For best adhesion, the dry film thickness of Chemlok459X primer should be about 2.5 microns (0.1 mil).
Drying / curing: At room temperature, fully ventilate the primer for natural drying for 30-60 minutes, or use an oven at a temperature of 93-121 ° C (200-250 ° F) for 5-10 minutes. Thermal cycling usually improves adhesion.
Removal: Use a dry rag to remove the wet primer. Use xylene or ketone solvents to remove the dried primer.
Shelf life / storage requirements
From the date of shipment, the shelf life is half a year when stored in the original unopened container at 21-27 ° C (70-80 ° F).
