These are glues based on organic solvents (alcohols, ketones, etc.) containing a fixing agent made of rubber, polyurethane or polychloroprene in the case of neoprene glue. They are generally transparent with sometimes a yellowish tint. They can remain flexible after drying which makes them interesting for gluing leather or skai. With contact glues, you can glue porous, smooth or hard materials as well. The resulting interface will be resistant if the bonding surface is large enough.
To fix two surfaces with a contact adhesive, it is necessary to glue the two surfaces of contact. Allow the glued surfaces to dry for 10 to 60 minutes (depending on the solvent). To make sure you can join both surfaces, do a test with your finger. If the glue does not smudge anymore, ie if the glue did not settle on your finger then, you can glue both surfaces. To ensure effective bonding, gently approach both surfaces and once the contact is made squeeze the parts you want to attach for 5 seconds. The final decision will be made after 1 to 3 days. If you want to work (sawing, drilling...) assembly, wait 24 hours.
On which supports:
Wood, metal, glass, porcelain, cork, leather, rigid or flexible PVC.
Media that does not stick with:
Polyethylene, Polystyrene, polypropylene.
Uses for the house:
Glue wood in hard-to-reach areas where screwing or nailing is not obvious. Attach gutters or PVC pipes.
Contact glues can stick many materials. They are very resistant and therefore allow lasting collages.
Low tensile strength. Does not fit small areas...
To wash instruments after use:
Use an organic solvent such as white spirit, gasoline or acetone.
