Summary: | Method for bonding a thermoplastic piping system (1) without the use of solvent-based adhesives, the piping system (1) comprising at least one first pipe or fitting part (11), and at least one second pipe or fitting part (12), which comprises the steps of i) applying a cyanoacrylate adhesive (2) onto at least one surface of the at least one first pipe or fitting part (11), or at least one second pipe or fitting part (12), ii) inserting together the at least one first pipe or fitting part (11), and the at least one second pipe or fitting part (12) before an open time lapses, iii) removing the excess of cyanoacrylate adhesive (2), iv) allowing the adhesive to cure. Associated adhesive for bonding a thermoplastic piping system (1) without the use of solvents, comprising a cyanoacrylate monomer (21), a polymerization inhibitor, a viscosity thickener, and a curing speed adjusting catalyst.
L'invention concerne un procédé de collage d'un système de tuyauterie thermoplastique (1) sans l'utilisation d'adhésifs à base de solvant, le système de tuyauterie (1) comprenant au moins une première partie tuyau ou raccord (11) et au moins une seconde partie tuyau ou raccord (12), le procédé comprenant les étapes consistant à i) appliquer un adhésif à base de cyanoacrylate (2) sur au moins une surface de ladite ou desdites premières parties tuyaux ou raccords (11) ou de ladite ou desdites secondes parties tuyaux ou raccords (12), ii) assembler ladite ou lesdites premières parties tuyaux ou raccords (11) et ladite ou lesdites secondes parties tuyaux ou raccords (12) avant un laps de temps ouvert, iii) éliminer l'excès d'adhésif à base de cyanoacrylate (2) et iv) laisser l'adhésif durcir. L'invention concerne également un adhésif associé pour le collage d'un système de tuyauterie thermoplastique (1) sans l'utilisation de solvants, comprenant un monomère cyanoacrylate (21), un inhibiteur de polymérisation, un épaississant augmentant la viscosité et un catalyseur ajustant la vitesse de durcissement. |
