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 ACRIFIX^® TC 0030, scrape cut surface, remove bubbles using a paintbrush and ACRIFIX^® TC 0030.
 
- Bubbles caused by excessive heat development during polymerization
Reduce layer thickness, slightly reduce hardener quantity, add ACRIFIX^® MO 0070, 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.
