PARALOID™ B-66 100%

PARALOID™ B-66 100% Resin thermoplastic acrylic resin is an excellent general-purpose resin with the same characteristics as the solution grade. In appropriate solvents, PARALOID™ B-66 100% Resin acrylic resin forms clear solutions, which air-dry extremely fast to form hard, colorless films which display excellent block resistance and color retention.

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 to approx. 1.2 dry mils.
  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.

Storage & Handling

Storage Conditions
  • Keep combustible and/or flammable products and their vapors away from heat, sparks, flames and other sources of ignition including static discharge.
  • Processing or operating at temperatures near or above product flashpoint may pose a fire hazard. Use appropriate grounding and bonding techniques to manage static discharge hazards.
  • Failure to maintain proper volume level when using immersion heaters can expose tank and solution to excessive heat resulting in a possible combustion hazard, particularly when plastic tanks are used.
  • Store products in tightly closed original containers at temperatures recommended on the product label.
