Surface Preparation/Pretreatment

Cleaner – Primer – Activators

Cleaner

For every application in which an adhesive is used, clean, grease-free and dry surfaces of the parts to be joined are a necessary prerequisite for achieving a sufficiently high level of adhesion (surface adhesion). DREI BOND cleaning products are highly effective in removing grease, oil and dirt from metallic and non-metallic surfaces. The DREI BOND Super Cleaner can be used to support the removal of cured adhesive and sealant residues.
 

Primer

For substrates that are difficult to bond (ex. PP, PE, etc.), adhesive- and material-specific primers can be applied to the component before the adhesive is applied. Primers act as an adapter between the component material and the adhesive. They thus enable good adhesion between the component and the adhesive and consequently a stable bond.

Activators

In particular with anaerobic adhesives in connection with passive surfaces, activators can ensure fast and guaranteed curing of the adhesive. These are applied directly to the passive surface and accelerate the curing of the subsequently applied adhesive. The activator can be applied using a spray bottle or as a liquid and can be carried out many hours before the adhesive is applied.
