DOWNLOAD Technical Data Sheet

PARALOID™ B-66 100% solid-grade thermoplastic acrylic resin is designed for use in protective coatings for concrete, masonry, metal, and plastic applications. This general-purpose resin has the same characteristics as the solution grade. In appropriate solvents, it forms clear solutions that air-dry extremely fast to form hard, colorless films with excellent resistance properties and color retention.

Typical applications

  • concrete and masonry sealers
  • traffic paint
  • clear aerosols
  • graphic arts and gravure printing inks
  • protective coatings for plastics (ABS, polycarbonate and polystyrene)
  • general metal protective and decorative coatings

Performance advantages

  • fast solvent release
  • outstanding toughness and durability
  • good water resistance
  • good salt-spray resistance
  • color retention
  • soluble in many different solvents
  • compatible with many different resins


These properties are typical, but they do not constitute specifications.
