Description
Weicon Contact VA 180 HT is a transparent cyanoacrylate adhesive for special requirements. It is high-temperature-resistant up to +180 Deg.C, fast-curing and odourless, and has medium viscosity. The cyanoacrylate adhesive is suitable especially for the fixation of components, which are exposed to strong temperature fluctuations, for example when close to a running engine. Weicon Contact VA 180 HT can be used in various industrial applications, such as in lamp and lightning construction, in the production of kitchen and electronic devices, or in areas where high temperatures can occur and a quick solution is needed.Surface pre-treatmentFor a flawless adhesive bond, surfaces must be clean and dry (clean and degrease with WEICON Surface Cleaner). Smooth surfaces should be roughened mechanically. To improve the adhesion of plastics difficult to bond (e.g. PE, PP, POM, PTFE), thermoplastic elastomers (TPE) and silicones, WEICON CA-Primer can be applied to the bonding surface. ProcessingApply WEICON Contact Cyanoacrylate Adhesive to just one of the bonding surfaces. The layer thickness when applying the adhesive should be between min. 0.05 and max. 0.2 mm (depending on the type), as otherwise complete curing cannot be guaranteed For large-surface bondings, WEICON Contact Cyanoacrylate Adhesives should be applied in dots in order to prevent inner tensions. WEICON Contact Cyanoacrylate Adhesives are very economical. One drop covers approx. 3 to 5 cm² bonding surface. The components should be bonded at a relative air humdity level between 40% and 80%. Below 40 %, the curing process is slowed down significantly or even prevented altogether. At an air humdity level above 80 % or with strongly basic substrates (e.g. glasses), the risk of shock-curing occurs. In these cases, certain materials show a drop in strength by 10 % to 15 % due to tensions in the adhesive layer. Alkaline surfaces (pH value >7) accelerate the curing process, acidic surfaces (pH value <7) slow down the curing process and can prevent polymerisation altogether in extreme cases. StorageWEICON Contact Cyanocrylate Adhesives have a shelf life of at least 9 months, when stored in unopened condition at room temperature (+18 Deg.C to +25 Deg.C) in a dry and dark space. Temperatures of approx. +5 Deg.C will increase the shelf life to 12 months.
