Double Sided Acrylic Core Adhesive Tapes for High Performance Bonding

Constructive bonding is a key element in every industry and can be very challenging. For many applications, high-tech materials are used that have special structures and properties that need to be maintained. Often dissimilar materials need to be bonded - for example aluminium on steel, steel on glass, deco glass on fibre composites, etc. Traditional mechanical fasteners like rivets, welds, screws, or liquid glue may not be suitable or can even damage these materials.

That is where our high performance bonding tapes come into play: tesa®ACX^plus - an acrylic foam double sided tape with very special bonding capabilities.

tesa® ACX^plus double sided bonding solutions can outperform conventional fastening methods by optimising our customers’ production processes and the quality and aesthetics of their products.

The tesa® ACX^plus double sided tape is characterised by its strong bonding power. Applied loads like wind, snow and the permanent load of bonded components can be accommodated by tesa® ACX^plus without problems.

tesa® ACX^plus has a powerful, high bond on materials with different surface characteristics because the acrylic adhesive system used enables optimal wetting and chemically adapts to the bonded surfaces.

Even more, the tape thicknesses can be adjusted to compensate for rough and uneven surfaces. The result is a permanent contact and a complete sealing of the bonded substrates. This leads to a high strength bond that will last for decades.

Even LSE ( Low Surface Energy) materials can be bonded with tesa® ACX^plus709x. tesa® ACX^plus709x is our new LSE performer featuring an innovative adhesive layer which makes strong bonds possible to low surface energy materials such as polypropylene, polyethylene and powder coatings without the requirement for a surface pre-treatment (e.g. adhesion promoter).

Additionally tesa® ACX^plus709x can be applied at temperatures as low as 0ºC making it suitable for use in cold or unheated production environments. Featuring an innovative adhesive layer which makes strong bonds possible to low surface energy materials such as polypropylene, polyethylene and powder coatings without the requirement for a surface pre-treatment (e.g. adhesion promoter).

Aluminium on steel, steel on glass, deco glass on fibre composites – dissimilar materials show different elongations when temperatures change. During the life cycle of a component, static and dynamic forces act upon the constructive bond. Stress arises that needs to be dissipated. tesa® ACX^plus is able to dissipate these. The high performance of tesa®ACX^plus double sided acrylic foam tapes is based on a special feature: viscoelasticity. Viscoelasticity describes a material performance which is defined by both elastic and viscous characteristics.

The elastic restoring forces provide inner strength while the viscous part of the material behaviour leads to relaxation of mechanical stresses. tesa® ACX^plus employs a special acrylic adhesive system that combines both effects in an outstanding way.

Due to the viscoelastic behaviour of tesa® ACX^plus arising stresses can be optimally dissipated and a secure bond is assured. Extreme temperature changes are accommodated even for bonded substrates with different elongation characteristics.

Finland or Arizona, inside or outside – constructive bonds can be found anywhere. Different weather conditions like rain, snow, penetration by UV light or humidity as well as very low and very high temperatures – a constructive bond has to withstand many external influences.

If materials are bonded with traditional mechanical fasteners like screws, rivets or welds, they can be vulnerable to corrosion, which leads to damage and requires costly reconstruction. 

tesa® ACX^plus acrylic foam double sided tapes offers a high resistance to temperatures and different weather conditions. The main reason is the oxidation resistance of the fully saturated carbon chain which is the foundation of the acrylates used in tesa® ACX^plus. Furthermore, the special curing chemistry forms an outstanding temperature resistance structure.

This results in a superior bond that shows excellent resistance to temperature, weather, UV and chemical influence.
