Technicoll® 8044 is suitable for contact bonding of many different plastics and other materials, especially for plasticised materials. technicoll® 8044 can either be used with or without adding cross linking agent technicoll® 8355. When used in combination with technicoll® 8355, the resistance to plasticisers, aging, water and heat is increased.
- Favoured Substrates
- ABS, SAN, PVC-u, PA
- Elastomers (PUR and nitrile rubber)
- Derived timber product
- PVC-p, faux leather
- Leather, textiles
- PUR, PUR-foam
- Polycarbonate (PC)
- Painted and coated surfaces
- Polyester (PET)
- PMMA
- Fiber reinforced plastics (FRP)
- Cellulose ester
- Not suitable for: PE, PP, PTFE (Teflon®), POM, silicone, EPDM, EPS, XPS (e.g. Styropor®), metals
- 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.
- Application & Uses
Surface preparation
Joint surfaces must be dry and clean, especially free of oil, grease or release agents. In order to clean surfaces, technicoll® 8363 is recommended. In many cases, surface roughening prior to bonding improves strength of bonded joint. This is especially recommended when bonding elastomers.
Addition of cross linking agent
Technicoll® 8044 can be used with cross linking agent technicoll® 8355. technicoll® 8355 increases the heat and water resistance and is recommended when adhesion requires resistance to heat > +50 °C, or is constantly exposed to weather conditions or water.
Adhesion
Apply a thin layer of technicoll® 8044 equally to both sides of the joint surfaces (brush, trowel, closed roller). The adhesive will be sprayable by adding 20 - 25% diluting agent technicoll® 8362. Drying time and contact life of cold bonding are half as long as the above mentioned times. Cold bonding: After applying technicoll® 8044, the solvent needs to evaporate for 5 - 10 minutes. Join the substrates together accurately and assemble quickly under high pressure. Heat bonding: After applying technicoll® 8044, the solvent needs to evaporate completely (at least 30 minutes). Join the substrates together accurately and assemble under high pressure at 80 °C. Apply pressure until the bonding joint has cooled down. Adhesion has a high initial strength. Wait for a couple of days before assessing the final strength.
