CELOCOR® opaque polymers are highly efficient, voided latex products that improve hiding and whiteness in paints and coatings, and function as a partial replacement for titanium dioxide (TiO2). With the introduction of CELOCOR® AF opaque polymer you have even more choice, with a new product that offers important benefits.

 

  • No Ammonia – CELOCOR® AF opaque polymer is ammonia-free, making it a perfect choice for low odor interior or exterior coatings.
  • Better Hiding – compared to our original CELOCOR® opaque polymer, this new product offers up to 11% better hiding with excellent tint strength properties.
  • Excellent Efficiency.
  • Wide Formulating Latitude – useable across a broad PVC range.
  • EnVia® Certified – new CELOCOR® AF opaque polymer meets Arkema’s internal standards for raw materials used in sustainable formulating

Performance evaluations

Interior flat contractor paint based on ENCOR® 282 latex (VAE)

  • Control paint
  • PVC = 56.3%
  • Volume Solids = 30.7%
  • TiO2 = 200 lbs (19.5% PVC)
  • OMYACARB® 3 = 80 lbs
  • CELOCOR® AF-modified paint properties
  • PVC = 59.0%
  • Volume Solids = 32.7%
  • TiO2 = 183 lbs (16.8% PVC)
  • OMYACARB® 3 = 90 lbs
  • CELOCOR® AF = 37.4 wet lbs (7% PVC)

Formulating Tip: Reducing volume solids back to the original level of 30.7% allows for the formulation to be diluted by 6.5%, resulting in a reduction of TiO2 to 183 lbs per 100 gallons and CELOCOR® AF to 37 wet lbs.

Performance properties should be evaluated.

 

CELOCOR® AF displays excellent hiding in VAE-based interior flat paints

CELOCOR AF interior flat paint

  • Results indicate the TiO2 level could be reduced by an additional 10-12%, while still maintaining equivalent Tint Strength as the control
  • The contrast ratio is maintained with the addition of CELOCOR® AF

 

Equivalent scrub and burnish resistance in CELOCOR® AF-modified interior flat paints

CELOCOR AF VAE based flat paint

  • Scrub resistance is within the normal variation for ENCOR® 282 VAE-based flat paint

 

Adding CELOCOR® AF can improve washability in VAE-based flat paints

CELOCOR AF vae-based flat paints washability

  • CELOCOR® AF gave the best overall washability except against Yellow Mustard

 

Interior/exterior semi-gloss paint based on SNAP® 720 acrylic latex (100%)

  • Control paint properties
  • PVC = 25%
  • Volume Solids = 35.3%
  • TiO2 = 250 lbs (21.6% PVC)
  • MINEX® 10 = 25 lbs
  • CELOCOR® AF-modified paint properties
  • PVC = 30.3%
  • Volume Solids = 37.4%
  • TiO2 = 230# (18.4% PVC)
  • MINEX® 10 = 32 lbs
  • CELOCOR® AF = 50 wet lbs (8% PVC)

Formulating Tip: Reducing volume solids back to the original level allows for the formulation to be diluted by 6.5%, resulting in a reduction of TiO2 to 230 lbs per 100 gallons and CELOCOR® AF to 50 wet lbs.

Performance properties should be evaluated.

 

CELOCOR® AF displays excellent hiding in acrylic semi-gloss paints

CELOCOR AF semi-gloss paint

  • The contrast ratio improves with the addition of CELOCOR® AF
  • Results indicate that the TiO2 level could be reduced by 6-8% and still achieve Tint Strength equivalent to the control

 

Gloss and block resistance is equivalent

Snap 720 gloss and block resistance

  • Equivalent gloss development is achieved when adding CELOCOR® AF compared to a control
  • Adding CELOCOR® AF had no adverse effects on SNAP® 720's outstanding block resistance

Scrub resistance is within the expected variation of semi-gloss acrylic paints based on SNAP® 720
