LOCTITE TP 650

Features:

• Provides strong adhesive strength between substrate and coating.
• Usable for multiple substrates.
• Can provide low friction coatings with enhanced abrasion resistance performance for weather- strip seals.
• Very low solids content.

Benefits:

• Robustness in durability and performance of applied coating.
• Economic savings by use of one primer for rubber or plastics.
• Enhances robustness of produced part that results in improved quality and customer satisfaction.
• Cost-savings through reduced inventory and dilution extension for non-critical applications

• Priming of EPDM rubber and thermoplastic substrates prior to application of a top coat.
• Theoretical Coverage : app. 17 m²/kg at 1 μm

Surface Preparation

Surfaces to be coated must be clean, dry and free from dust and grease. Usually an alcohol wipe is sufficient.

Mixing and Dilution

The product is supplied ready-for-use. Stirring or shaking the material is recommended prior to use to improve uniformity.

Application

The product can be applied by swab or spray application. It is preferable that only a thin even layer of coating be applied (app. 1 micron (0.04 mil) dry). For spray application in small volume production and prototype, a suction cup gun may be used. In full production a standard spray system designed to apply solvent- based coatings can be used. LOCTITE TP 650 should be applied as is for applications onto thermoplastic substrates and applications where maximum abrasion resistance is required.

Drying

Air dry the coated parts for 5 - 10 minutes at room temperature or for 60 - 80°C 1-2 minutes (depending on humidity) before applying final coating. Drying time for production operations can be decreased by passing coated parts through infrared heat, or through batch or conveyor ovens. When applying to hot substrates, ensure that primer does not boil or blister.
