Cure Wrap Tape Coatings
Extend the lifespan of cure wrap tapes
Our water-based cure tape coatings help protect tapes from physical and chemical degradation over time to extend their effective lifespan. These coatings form a durable but flexible coating that is unaffected by stretch, shrink, and compression and thermally stable to 500°F (260°C) or higher. Our cure tape coatings can be applied by the tape manufacturer or by hose producers before use.
Hose manufacturers wrap hoses in cure tape before vulcanization to ensure the quality, shape, and integrity of the hose during the curing process. During vulcanization, cure tapes, typically made of nylon, contract, creating a compressive force on the layers of hose material. This compression eliminates voids and helps to prevent delamination of the layers. Nylon tapes also keeps complex hoses from deforming during the vulcanization process under heat and promote a better surface finish post-cure. Finally, nylon tape coatings ensure uniform heat distribution around the hose and prevent adhesion of the rubber to other surfaces during the vulcanization process. While nylon tapes remain the most common, tapes made of other polymers, such as polyester or ETFE, may be used to provide higher and more controlled compressive force during vulcanization.
Our cure wrap tapes are suitable for use on traditional nylon tapes as well as the higher-shrink tapes becoming more common today. McLube has decades of experiences helping hose manufacturers optimize their process. Contact us for assistance with selecting the appropriate coating for your tapes.
