PARALOID™ B-72 100%

PARALOID™ B-72 100% Resin has low reactivity with sensitive phosphorescent and luminescent pigments to produce stable, durable, non-yellowing coatings. It is compatible with vinyls, cellulosics, chlorinated rubbers, and silicones. It is well suited for white and metallic aerosols, clear coatings for wood, nitrocellulose modified coatings for general product finishing, pigment dispersion (fluorescent), flexographic printing inks, and gravure plastic coatings.

Note

Drying the coatings at 300°F for 30 minutes simulates final properties of the resin.

  1. The white lacquers were formulated at a titanium dioxide/binder ratio (solids basis) of 30/70. The properties were determined after coatings were sprayed on Bonderite 1000.
  2. The degree of cracking at the bend over each mandrel is rated on a 0 (no failure) to 10 (complete flaking) scale.
  3. The degree of flaking at the scribed cross hatch is rated on a 0 (no failure) to 5 (complete lift off) scale.
