Bonding PLEXIGLAS®

- Bubbles due to stirred-in air 
  Degas adhesive compound.
- Bubbles introduced during bonding
  Apply adhesive without bubble formation; if necessary, enhance wetting-out by 
  pretreating the surface with THINNER AND CLEANER 30, scrape cut surface, 
  remove bubbles using a paintbrush and THINNER AND CLEANER 30. 
- Bubbles caused by excessive heat development during polymerization
  Reduce layer thickness, slightly reduce hardener quantity, add REACTION MODERATOR 70, 
  apply adhesive in several steps. 
- Bubbles due to uneven adhesive joint 
  Treat adherends mechanically to make them plane, space them more accurately. 
- Bubbles due to adhesive shrinkage or elastic recovery due to indrawn air 
  Apply a thicker or more even layer of adhesive if necessary, apply growing contact 
  pressure during the pot life until curing is completed.
- Bubbles due to soiled adherend surfaces 
  Thoroughly clean the surfaces to be bonded.
