Tape is black coloured on magnetic face. MagFlex magnetic tape is easily cut and effortlessly sticks onto variety of surfaces, including many plastics. MagFlex tapes 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.
