Many plastics cannot be glued or only to a limited extent without prior treatment. By pretreating these plastics with WEICON Contact Primer, a change in the surface structure is achieved. This enables the connection of plastics that are otherwise difficult to glue, e.g. polyethylene (PE) and polypropylene (PP) from the group of polyolefins. Modern thermoplastic elastomers (TPE), PTFE and related plastics as well as silicones can also be bonded after pretreatment with WEICON Contact Primer.
Processing: Brush or spray a thin layer of adhesive surfaces and allow to flash off briefly. Apply cyanoacrylate glue and join pieces together.
Storage: Keep away from sources of ignition - No smoking. Take precautionary measures against electrostatic charging. Keep container tightly closed in a cool, well-ventilated place. When unopened and stored in a normal climate (+ 23 °C and 50 % relative humidity), the CA-Primer can be used for 12 months.
Safety and health: When processing WEICON products, the physical, safety, toxicological and ecological data and regulations must be observed.
Hazard warnings: H225 - Highly flammable liquid and vapor. H304 - May be fatal if swallowed and enters airways. H314 - Causes severe skin burns and eye damage. H336 - May cause drowsiness and dizziness.
