Coveme DyBond® products are flexible insulating materials with a B-Stage (semi polymerized) resin. During our coating process the resin is first applied onto the substrate then, by controlled heating, the polymerization is started bringing the resin to the so called B-Stage, where it is almost dry, reasonably stable, but not fully polymerized. The final product depends on the substrate used for the resin coating.
The resin can be of various grammages and colours, coated on one or both sides, and on the full surface or with a diamond pattern. DyBond® B-Stage pre-pregs can be used by the manufacturer as any conventional insulating material. After the manufacturing operations the final equipment is exposed to heat. The resin will initially melt, creating a uniform distribution and filling any possible non uniformity, before polymerizing to its final solid stage cementing the DyBond® products to the conductors to be insulated. DyBond® is used as electrical insulator in mainly in electrical motors, generators and various types of transformers (TA-TV, cast resin, dry and oil filled, measuring, sf6 gas) as well as some types of rotating machines. Depending on the substrate used DyBond® is suitable for working temperatures up to class H 180°C.
