RHOPLEX™ I-62A Emulsion

A hydroxyl-functional and alkali-soluble acrylic copolymer supplied as an unneutralized aqueous colloidal dispersion. It has broad utility as a dispersant for organic and inorganic pigments, especially in coating formulations designed for thermosetting applications such as for wood and metal building products. RHOPLEX™ I-62A Emulsion offers excellent dispersion for whites and a variety of deeptone formulations. In thermosetting coatings, the hydroxyl and carboxylic acid groups crosslink with melamine-formaldehyde or urea-formaldehyde resins, thereby becoming part of the polymer matrix and improving the film properties. Readily neutralized, RHOPLEX™ I-62A Emulsion can also be used as a sole vehicle or as the letdown resin for inks for absorbent substrates.

Uses:

  • Pigment dispersions
  • Thermosetting industrial finishes
  • Graining inks
  • Graphic arts

Benefits:

  • High pigment dispersing efficiency
  • Broad formulation latitude
  • Improved water resistance of coating
  • Ability to crosslink through both hydroxyl and carboxyl functionality
  • Supplied un-neutralized, allowing choice of neutralizer for solubilization
