Adhesive Tapes are used in many sectors of industry on account of their excellent performance. They offer the unique advantage of economical, fast and clean processing compared with other mounting systems – both manual and automated. To ensure that the performance potential of our adhesive tapes is fully utilised, please follow the processing instructions listed below: The tape is typically applied during the body in white process. It is run through the automotive paint pre treatment process and then the e coat process. The tape expands and cures in the e coat cure oven to fill and seal small gaps. The tape forms a continuous barrier between similar and dissimilar materials, which minimizes electrical conductivity and helps prevent galvanic interactions. Plastic components are often fixed with the aid of adhesives to prevent them from slipping during further process handling. Acrylate-based adhesives in particular usually adhere very well to many plastics. They have a strengthening and supporting effect for load transfer and stress reduction. Acrylic adhesives, which are also used for permanent bonding, are characterised by short processing times and high strength to many plastics and elastomers. These adhesives achieve, for example, as 2-component adhesives on low-energy plastics such as PC, PMMA, PVC etc., good shear and peel strengths as well as good impact strength under dynamic loads. From the 3M Scotch-Weld series, even acrylic adhesives have been developed in the meantime, which provide good results on difficult to bond plastics with low surface energy without any surface preparation or primer.
Physical surface treatment processes use high-energy electron, laser or UV radiation in this process or thermal processes such as flame treatment or electrical plasma or corona processes. They change the surface chemically and physically. When flaming plastics, an open flame is guided over the surface of the part to be joined at a defined distance and speed. The flame can be used in a reducing or oxidising manner, depending on the type of plastic to be flamed. This makes the component surface more energetic and easier to bond. By adding chemically reactive substances, the surface can be influenced even further.
Company Details
The flowable, red silicone rubber (RTB/HB) has a high heat resistance and low elasticity. They are used as mould construction material for casting moulds for low-melting metals where high hardness is required. With this information, the adhesive and surface treatment can be selected based on technical data sheets, experience and the literature. If it is important, adhesive samples should be made and tested before the adhesives are used. In mechanical testing, the bonded joint is loaded until it breaks. The type of fracture provides information about the quality of the bond and indicates where defects occurred during bonding. An adhesion fracture is when the adhesive detaches from the joined part. A cohesion fracture is a fracture in the adhesive itself and a fracture in the part to be joined describes a fracture outside the adhesive surface in the part to be joined.
Cleaning and degreasing the plastic surface of loosely adhering dust, oil, grease and separating and processing agents with water or solvents - this does not change the structure of the surface. Cleaning can be carried out by immersion or spraying. Degreasing is done with organic solvents or by pre-drying in the oven. PA - polyamide is high-strength and impact-resistant. Its abrasion and wear resistance combined with excellent sliding properties make it a preferred construction material in machine or vehicle construction. Because of its high mechanical strength, it has now even displaced many metal components in vehicle construction - sometimes reinforced with carbon or glass fibres. But PA is not easy to bond. High bond strengths of PA materials require the use of special pre-treatment methods or specially developed, reactive adhesives. Further information. PMMA - polymethyl methacrylate, also known as Plexiglas and acrylic glass, impresses with its optical and surface properties. In everyday life, corrugated sheets, for example for the roofing of garden arbours or pergolas, are often mistakenly offered as plexiglass. In reality, they are made of polycarbonate or PVC, which can make a big difference when bonding the material. The same applies to so-called hobby glass from the DIY store. For bonding on low-energy plastics such as PMMA, the surface energy is of central importance. However, caution is advised when using certain solvents for bonding preparation. Otherwise, there is a wide range of high-performance adhesives on the market for efficiently bonding PMMA to numerous other materials. Further information.In contrast, the low-viscosity, hot-crosslinked silicone rubber (RTV/NV) is medium-elastic, has good flowability and low viscosity. It is therefore particularly suitable for the manufacture of elastic wax or relief casting moulds, casting moulds for figures or decorative panels, moulds for casting with epoxy / casting resin, cement, plaster or other flowable materials. It has unparralelled long term and short term strength and boasts brilliant resistance to humidity, solvents , plasticisers and UV, salt water and alkalines. This tape withstands the test of time and weathering! Double-sided acrylate foam adhesive tapes for a wide range of applications are available on the market. They're made of closed-cell acrylate adhesive for demanding material combinations or critical plastics with low surface energy such as PE or PP. These are able to absorb forces well and are therefore permanently resistant to tensile, shear, splitting and peeling forces. They're suitable, for example, for car mirror bonding or for the bonding of mouldings and decorative trim. The cold-crosslinking HTV silicone rubbers are plastically deformable materials which are used, for example, as cable sheathing, for electrical insulation or for sealing and damping purposes.
