Bonding Preparation of Plastics – Laser Cleaning

Laser technology can be used for treating plastics to enhance adhesive bonding by removing surfaces contaminants such as release agents, residues and by creating a unique surface profile. The laser beam safely and precisely exposes a clean surface optimized for subsequent bonding.
Laser surface preparation has proven effective with carbon fiber reinforced polymers (CFRP) and plastics. Industries that require bonding to CFRP and PUR (Polyurethane) rubber have a long and successful history using laser technology.

BENEFITS

• Cleaning rates up to 80 m² / h, preparing PUR rubber for bonding
• Cleaning rates up to 50 cm² / sec, surface structuring/preparing CFRP for bonding

 
Laser effectiveness for the surface treatment of plastics is limited to those those that are pigmented/coloured, i.e., are able to absorb the laser beam’s wavelength.
