La renommée des produits Sikaflex n'est plus a faire, je m'en suis servi pour coller un élément plastique dans un lave-vaisselle, un support de roulettes pour le panier supérieur fixé sur le panneau inox. Le pochon de ce volume est idéal car on évite trop de gaspillage, la buse fait bien le job et permet d'étaler le produit avec précision. Attention tout de même!! le sertissage du pochon est fragile, bien appuyer régulièrement a partir du fond et attendre d'avoir passé 1 cm/1.5 cm de produit avant de passer la clé qui sert a pousser, sinon vous risquez de percer le pochon. ça fait un peu plus de 15 jours que j'ai fixé l'élément, rien n'à bougé malgré l'eau chaude, la vapeur et les pastilles de lavage.
