SALIENT CHARACTERISTICS

  • Excellent Hard Binder
  • Good backing binder for abrasive articles

MODE OF APPLICATION

  • 1. Resicryl H-845 is used for stiff finishes with better durability than the conventional polyvinyl acetate dispersions or vinyl acrylic copolymers. Resicryl H-845 is recommended for interlinings for permanent durability.
  • 2. For coated or backed abrasives : The coated abrasive consists of 3 layers: the backing, binder and the abrasive grain. Resicryl H-845 seems to be an ideal binder for getting the optimum performance. The recommended dosage level for polyester web is 20% of the binder and varies based on substrate and applications. Nonionic emulsifiers can be added to increase the workability and stability.
  • 3. For better crosslinking UF/MF resins can be used. Though the binder itself is self crosslinking, additional catalyst like ammonium nitrate or oxalic acid is recommended where faster curing is desired.
