Preparation of Adhesive tape

  • Acrylic resin emulsion(NV:65%)：Cross linker (as Solid)＝100：0.6
  • Substrate：PET film
  • Thickness：30µm
  • Cure condition：100℃×2min→60℃×24ｈ

Treating agent for fibers

Anti-wrinkle imparting agent for cotton fiber

Features
  • By cross-linking hydroxyl groups of fibers (cellulose), the structure is fixed, and wrinkles are less likely to form.
  • Improves a wrinkle-resistant property (anti-wrinkle), making it suitable in the development of handkerchiefs and shirts.

Resin stabilizer

Halogen Catcher

Features
  • Functions as a catcher of chlorine that is desorbed from chlorine-based resins (prevents resin deterioration)
  • Capturing hydrochloric acid to prevent acid deterioration and corrosion
Example of use
・In cases such as vinyl chloride emulsions, epoxy is used for aqueous resins.

Reactive diluent

Features
  • Addition of low-viscosity DENACOL to high-viscosity base resin improves handling property.
  • Unlike dilution with solvents, DENACOL has reactive functional groups, so there is no need to remove solvents before curing, and it can be cured with them.
