LORD 459X
Harmonization Code : 3208.20.90 | Paints and varnishes that are dispersed or dissolved in a non aqueous medium
Main features
- Adhesion-Promoting Surface Treatment
- Low-Viscosity Adhesive Application
- Brush, Dip or Spray Application
Product Description
LORD® 459X Adhesion Enhancer/Surface Modifier is a low-viscosity, xylene-based surface treatment designed to promote adhesion to difficult-to-bond thermoplastic elastomers, thermoplastic polyolefins and EPDM. Supplied pre-diluted for direct application, it can be used with LORD acrylic, urethane and epoxy structural adhesives, as well as compatible coatings and double-sided tapes. The material requires no mixing or additional dilution and can be applied by brush, dip or spray.
Key Features
- Promotes adhesion to difficult elastomers, including TPE, TPO and EPDM substrates.
- Ready-to-use formulation requires no mixing or dilution before application.
- Low-viscosity application supports brush, dip and spray methods.
- Low dry-film requirement with an optimum dry-film thickness of approximately 0.1 mil (2.5 µm).
Applications / Suitable for
- Surface treatment of TPE, TPO and EPDM
- Adhesion promotion for acrylic, urethane and epoxy structural adhesives
- Adhesion enhancement for coatings
- Surface preparation for compatible double-sided tapes
