Prox SBP 604

PROX ® SBP 604, by Synthron, is a new Core-shell based cationic emulsion specially designed for formulation of stain blocking primers. Waterborne primers based on PROX ® SBP 604 present excellent blocking properties against stains such as ink markers, coffee, nicotine, oily stains, etc.

Information obtained from:

Technical characteristics: 

  • Appearance : Low viscous milky emulsion
  • Dry matter : 44 % ± 1
  • Solvent: Water
  • pH : 5,7
  • TMT : 0 °C


Schematic mechanism: Stains could be classified by chemical affinity: Hydrophilic or solvent soluble structure.
Solvent soluble components could be extracted by solvent borne systems, and then migrate into the film, bringing coloration to the paint, such as oil stains, wood resins, smoke component, tars. Using a waterborne primer creates a barrier to those components.
Hydrophilic structure components have mainly alkaline affinity, such as foods stains, coffee, tannins and their alkaline salts, inks; they are incompatible with acidic pH. Using cationic water based binder displaying an acid pH to formulate primers will block the possible extraction and migration on those components into the film.
Because of its specific cationic chemistry and Core-shell design, stain blocker preparations based on PROX ® SBP 604 have excellent blocking properties to shield stains such as waterborne inks and markers, coffee, nicotine or oil.
PROX ® SBP 604 should be used as main resin in order to prepare stain blocker primer paints.
A VOC-free binder, PROX ® SBP 604 is especially recommended for primers for interior decorative applications, such as coatings for bedrooms, kitchens. It displays an excellent water resistance.

Ecronova RA 180 Plus

CINCINNATI, OH (April 14, 2016) – Michelman’s Ecronova™ RA 180 Plus is a new water-based cationic emulsion of an acrylic copolymer used as a binder for wood primer, paint and coating formulations.

With its cationic chemistry, Ecronova RA 180 Plus is preservative free, and is exceptionally effective as a barrier to tannin and nicotine stains when used in wood primers. Because of its resistance to stains, combined with good scrub resistance, Ecronova RA 180 Plus is also effective for use in 2-in-1 wall paint formulations.

Ecronova RA 180 Plus is solvent and surfactant free and because it does not require coalescents, can be formulated into a very low VOC paint. It also provides outstanding adhesion, as well as water and alkali resistance.

Michelman’s family of Ecronova RA high quality acrylic polymer dispersions are designed for use as binders in a wide variety of applications, including specialty architectural and industrial coatings, interior and exterior building paints, durable wood coatings, and concrete coatings.
