tesa® 51014

215 μm double sided translucent non woven tape with asymmetrical product design.

Product Description:

tesa® 51014 is a double-sided industrial mounting tape consisting of a non-woven backing and a highly tackified acrylic adhesive. The asymmetrical non-woven tape is especially designed for excellent performance on rough surfaces like leather and textiles, or plaster and stone.

The liner-covered side of tesa® 51014 has a high coating weight for maximum flexibility and versatility for multiple surface demands, particularly very rough surfaces. The open side has a reduced coating weight that delivers a secure bond to flat surfaces under controlled conditions. The mounting tape is able to withstand numerous environmental factors such as humidity, UV light, and temperatures of up to 200°C for limited periods of time. The tackified acrylic adhesive offers excellent hold on various surfaces, very high tack, and good shear strength. The adhesive is coated on a flexible and conformable cellulose non-woven backing that even conforms to difficult 3D shapes.
