WEICON Contact Filler, Primer and Activator
Without pre-treatment, many plastics are unable to bond or bond only under certain conditions. When these plastics are pre-treated with WEICON Contact Primer, their surface structure changes. Thereby the joining of plastics, like polyethylene (PE) and polypropylene (PP) belonging to the polyolefine group, which are usually difficult to bond, is made possible.
Even modern thermoplastic elastomers (TPE), Teflon® (PTFE) and related plastics as well as silicones, can be bonded when pre-treated with WEICON Contact Primer.
Thus, the following advantages arise:
The effectiveness of WEICON CA-Primer begins approx. 2 minutes after application and lasts up to approx. 24 hours.
Teflon® = registered brand name E.I. DuPont
The Activator speeds up the curing process of WEICON Contact Cyanoacrylate Adhesives. When applied to absorbing surfaces, like for example wood or foam etc., and all chemically-treated surfaces, like for example zinc galvanized metals etc., the Activator’s effectiveness lasts approx. one minute. With non-absorbent surfaces the Activator’s effectiveness lasts up to approx. twelve hours.
Use is recommendable with:
All specifications, recommendations and techncial data are based on laboratory tests under optimum conditions resp. on practical experience. They have been compiled most carefully. Nevertheless, a claim cannot be derived from them. We therefore recommend to carry out own tests before application. The user bears the only responsibility for non-appropriate or other than specified applications.
