  10. 10. Market Environment: Growing segment due to versatility Variety of compositions Cost / Competitiveness – Quality Technical Challenges - ADHESION: Crystallinity Polarity Surface Tension Shrinkage ALL of these vs. Mechanical and Chemical Performance (Toughness/Flexibility, Scratch and chemical resistance, yellowing, monocoats)

  13. 13. When the liquid meets the solid – Contact Angle
  14. 14. CHALLENGES for UV curing: POLARITY of regularly used components, which leads to higher surface tensions SHRINKAGE of the cured film due to retraction during the conversion of monomers and oligomers into a polymer
  15. 15. ROUTE PRODUCT Effect Lowering the Tg of the ink formulation EBECRYL® 745 EBECRYL® 767 (acid modified) EBECRYL® 8411 (300% elong.) EBECRYL® 242 Less double bounds in the system will lead to a lower shrinkage of the film, helping on the adhesion. Improve interaction between the film phase and the substrate EBECRYL® 436 EBECRYL® 438 EBECRYL® 524 (acid modified) chlorination plays an important adhesion promoting role. Surface tension balance EBECRYL® 303 Better substrate wetting enabling good adhesion and leveling Addition of acidic modified methacrylate adhesion promoters EBECRYL® 168 EBECRYL® 170 EBECRYL® 171 Substrate anchoring promotion Substrate pre-treatments, such as corona or flame treatment. Even the use of primers.
