Technicoll® 8055

Fast handling multifunctional contact adhesive with high initial tack and long contact life for porous substrates. Adhesion caused by technicoll® 8055 shows an excellent heat and water resistance (DIN 68705/AW100-test).

• Rubber
• Metals
• Expanded rubber to each other and:
• PUR foam
• Fabrics, textile
• Derived timber products
• Leather
• Coated surfaces (primed, painted)
• Cork
• Plastics unplasticised
• Not suitable for: PE, PP, PTFE (Teflon®), POM, silicone, EPDM, PVC-plasticised (faux leather) PS-rigid foams (e.g. Styropor®)
• Due to the large variety of possible materials and differences in adhesion behavior hazard tests are mandatory before introducing the adhesive into the actual production process.

Surface preparation

Bonding surfaces must be dry and clean, especially free of oil, grease or release agents. In many cases, surface roughening prior to bonding improves strength of bonded joint. It is recommended when working with rubber and metals.

Adhesion

Stir adhesive before use. Apply a thin layer of technicoll® 8055 equally to both sides of the bonding surface of the substrates (brush, spraying gun). After the application solvent needs to evaporate. The usual waiting time is just a few minutes. It depends on the applied amount of adhesive and the indoor climate. The right time for the bonding has come as soon as the applied adhesive does not pull strings anymore when touching with the finger, but still feels very sticky. Join the substrates together accurately and assemble quickly under high pressure. The good bond strength that is achieved immediately, usually allows further processing with the bonded substances right away. Completely dried but not finally cured layers of adhesive can be activated by applying a solvent like technicoll® 8367. Wait for a couple of days before assessing the final strength.

At least 18 months when stored in sealed original packaging in cool and dry places.
