  • b. Low initial adhesion (Tack) Reduced compatibility with substrate, high cohesiveness
  • c. High cohesion Excellent heat and chemical resistance of adhesives
  • d. Can be attached to high squeezing force
02. Technical characteristics
  • a. Product design technology considering the physical properties of PU foam (CFD, Foam Density)
  • b. PU Foam and combination based on high-reliability new PSA Recipe development technology
  • c. Process conditions (coating, lamination, etc.) optimization technology
03. Maximize performance
  • a. Maximization of adhesion characteristics: Normal temperature test, low temperature test, high temperature test, storage test, aging test
  • b. Maximize retention characteristics: Normal temperature test, low temperature test, high temperature test, high temperature and humidity test
  • c. T-Block characteristics maximized: Adhesion Retention T-Block Test, T-Block Limit Test
  • d. Understanding and utilizing PU Foam specifications (foam density, CFD, Skin/Foam thickness)
