A non film-forming, low-odor synthetic pigment engineered to improve the economics of waterborne coatings.
ROPAQUE Ultra EF shows increased light scattering efficiency compared to previous Opaque Polymer products, while maintaining paint performance.
The addition of the product to paints allows for the formulator to remove TiO2 in a paint while maintaining the same level of dry hiding in the coating.
ROPAQUE Ultra EF expands the boundaries of light scattering technology, one of the most efficient dry hiding in interior and exterior coatings.
Additionally, this non-film-forming synthetic pigment is specially engineered to improve the economics of waterborne coatings while maintaining coating performance.
ROPAQUE Ultra EF is a hollow-sphere polymeric pigment that allows paint manufacturers to reduce the raw material cost of their formulations with little to no performance penalties.
ROPAQUE Ultra EF is the most efficient product in the ROPAQUE Opaque Polymer product family.
ROPAQUE Ultra EF is neutralized with ammonia, and ROPAQUE Ultra EF Ammonia-free Opaque Polymer is neutralized with sodium hydroxide.
In addition to offering efficient dry hiding, ROPAQUE Ultra EF Ammonia-free Opaque Polymer offers wide range benefits in interior and exterior paint formulations.
ROPAQUE Ultra EF is a non-film forming, acrylic polymer hollow-sphere opaque pigment allowing manufactures to reduce formulation costs without sacrificing properties by being one of the most efficient dry hiding capabilities for interior and exterior coatings.
ROPAQUE Ultra EF is neutralized with ammonia.

Handling And Storage of ROPAQUE Ultra EF:
As with most emulsion polymers, some special storage and handling techniques should be observed for ROPAQUE Opaque Polymers.
Surfaces that will be in Contact with ROPAQUE™ Opaque Polymers:
Avoid using mild steel, iron, copper, brass, bronze, aluminum or zinc materials that could contact the ROPAQUE Opaque Polymers upon transfer and in storage.
Avoid using surfaces that enable the polymer to wick out, as the wicking process causes the development of nodules of hard materials that grows out from these areas and eventually drop into the polymer.
Examples of materials that could result in wicking are old fiberglass tanks with exposed glass fibers, a coated tank with part of the coating broken, and drums with pinholes in the lining.
Contamination:
Shared transfer lines and other components should be flushed with water before they are used for ROPAQUE Opaque Polymers.
Contact with concentrated glycols, surfactants and acid materials, could cause gelling.
Compatibility with all new materials should be checked routinely.
Filtration and Pumping:
Exposure of opaque polymer to high shear will cause mechanical breakdown and polymer build up.
Examples of high shear situations include pumping through small mesh filters at high flow rates and use of pumps with close tolerances.
ROPAQUE Opaque Polymers are dilatant products and can blind small pore filters.
For off loading, a 400 micron filter should be adequate.
When filtering with absorbent elements, pre-wetting the element reduces binding.
Cartridge filters and bag filters with needle punched filter bags are examples of filters with absorbent elements.
Foam:
Free fall during unloading should be avoided since ROPAQUE Ultra EF is a prime cause of foam in emulsion products such as ROPAQUE Opaque Polymers.
To prevent foaming, storage tanks should be filled from the bottom or through a dip pipe that extends down into the tank below liquid level.
Bulk Storage:
Intermittent agitation during bulk storage (approximately 15 minutes every 12 hours) is recommended for controlling sedimentation.
A two-inch recirculating closed loop, using a sliding van design, diaphragm type, or other low-shear pump to transfer material, is preferred to a top-entering agitator.
The recirculating loop should discharge below the liquid level of the polymer to avoid foam generation.
Precautions for safe handling:
Avoid contact with eyes, skin and clothing. Wash thoroughly after handling.
Keep container tightly closed.
Do not breathe vapors, mist or gas.
