Technicoll® 8150 is a sprayable, unfilled contact adhesive with a long open time and resistant to water, humidity and heat.
Applications & Uses
- Markets
- Application Method
- Field Of Application
Bonding of insulation materials such as unplasticised foam material, mineral fiber mats, glass fiber mats, felt, metal, render, concrete, bituminised felts, aluminum foils and different kinds of unplasticised polymeric films.
- Favoured Substrates
- Foam material (unplasticised)
- Metal
- Glass fiber mats with:
- Concrete, render
- Felt
- Aluminum foil
- Mineral fiber mats
- Derived timber products
- Plastic films (unplasticised)
- Not suitable for: PE, PP, PTFE (Teflon®), POM, silicone, EPDM, PVC-p (faux leather)
- 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
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® 8150 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. In some cases a one-sided application might be possible: Apply a thick layer of technicoll® 8150 equally to one side and join both surfaces immediately. Wait for a couple of days before assessing the final strength.
