This easy to cut MagFlex magnetic tape effortlessly sticks onto variety of surfaces, including many plastics. If your project requires tape to tape attraction, in order to avoid issues with misalignment use polarity A with polarity B magnetic tape. Our MagFlex magnetic sheets utilise a firm acrylic pressure-sensitive adhesive that substantially increases in bond strength with natural aging. While the initial touch bond strength is enough to keep the grip secure, to ensure the adhesive can withstand the pull strength we recommend allowing between 24 to 32 hours for the adhesive to fully cure. To ensure that the grip remains secure, we recommend allowing between 24 to 32 hours for the adhesive to cure.
