New tape bonds varied substrates

Adhesive tape manufacturer Tesa has developed a 'constructive bonding' tape that enables substrates with different thermal coefficients and surface roughness to be bonded for 'decades' in outside applications.

The tape's viscoelastic properties allow it to endure dynamic and static stresses with temperature variations, water, UV light and even exposure to chemicals. Additionally, a powerful bond on materials with different surface characteristics can be achieved because the acrylic adhesive system enables optimal 'wetting' and chemically adapts to the bonded surfaces.

Jochen Fiencke, international product manager at Tesa, said: "This is not just an alternative to traditional mechanical fastening methods; it offers significant advantages which can be seen in its bonding power, its stress dissipation and its temperature and weather resistance."
