OPAQUE POLYMER
Opaque polymer additives offer a cost-effective solution by partially replacing titanium dioxide (TiO2) in white and pastel paint formulations, helping paint manufacturers achieve opacity, gloss, and brightness while reducing raw material costs.
With its hollow-sphere structure, Opaque polymer provides consistent hiding power through controlled air voids, allowing for efficient light scattering without compromising paint performance or resistance properties.
Research indicates that Opaque polymer can economically replace 10 to 20% of TiO2 in architectural paints, sparking interest in its use for higher levels of TiO2 replacement in various paint formulations, including mid-tone tint bases and primers.

Opaque polymer is a hollow-sphere polymeric pigment that allows paint manufacturers to reduce the raw material cost of their formulations with no performance penalties.
Adding Opaque polymer to conventional paints allows the paint manufacturer to reduce the initial level of TiO2 and provide significant cost savings with equal properties.
Because Opaque polymer has a comparatively low binder demand, the total PVC can be slightly increased without sacrificing paint performance.
The extender levels may need to be rebalanced to adjust gloss by adjusting the ratio of large and small particle size extenders, and the water level and thickener may need to be adjusted to keep volume solids and viscosity constant.

Opaque polymer is an organic opacifier for water-based paints and coatings, mainly white and pastel formulations.
To a certain extent, using Opaque polymer enables white and pastel paints and coatings formulators to decrease their titanium dioxide consumption.
Current market conditions related to the rising cost of TiO2 allow this product to deliver value at higher levels of TiO2 replacement and in more formulating spaces.
Opaque polymer was developed to supplement titanium dioxide (TiO2) in paint formulators with a light-scattering pigment.
The hollow-sphere structure of Opaque polymer provides a controlled and consistent level of air void hiding in paint through the refractive index differential between the internal air void and the outer polymer shell.
The encapsulated air voids hide without losing resistance properties associated with other raw materials, which provide hiding through increased film porosity.
Extensive research and practical experience demonstrate that Opaque polymer may economically replace 10 to 20% of TiO2 in white and pastel architectural paints.
As a result, there is growing interest in using Opaque polymer at higher levels of TiO2 replacement in white and pastel acrylics.
This interest extends to using Opaque polymer in mid-tone tint bases, primers, and polyvinyl acetate (PVA) paints.

Specifications of Opaque polymer:
Chemical Composition:
Opaque polymer is typically a hollow-sphere polymeric pigment engineered for use in paints and coatings.
Its chemical composition may vary depending on the specific formulation and manufacturer, but Opaque polymer is designed to efficiently scatter light and improve opacity.
Particle Size:
The particle size of opaque polymer can vary depending on its intended application and manufacturing process.
Generally, Opaque polymer consists of hollow spheres with a controlled size distribution to optimize light scattering properties.
Opacity Enhancement:
Opaque polymer is designed to enhance the opacity of paints and coatings, particularly in white and pastel formulations.
Opaque polymer achieves this by effectively scattering light, which helps to obscure underlying surfaces and improve coverage.
Color:
Opaque polymer is often white or off-white in color to blend seamlessly with paint formulations.
However, Opaque polymer can be formulated in various shades to match specific color requirements.
Density:
The density of opaque polymer may vary depending on its formulation and manufacturing process.
Opaque polymer is typically engineered to have a density that allows for efficient dispersion in paint formulations without compromising the desired properties.
Binder Compatibility:
Opaque polymer is designed to be compatible with various binders commonly used in paints and coatings, such as acrylics, alkyds, and polyurethanes.
This ensures proper integration and stability within the paint matrix.
Application:
Opaque polymer is primarily used as an opacifier in water-based paints and coatings, although Opaque polymer may also find applications in solvent-based formulations.
Opaque polymer is suitable for use in architectural paints, primers, tint bases, and other decorative and protective coatings.
Performance:
Opaque polymer is engineered to provide consistent hiding power and opacity, even at relatively low levels of inclusion in paint formulations.
Opaque polymer contributes to improved coverage, brightness, and overall performance of paints and coatings.

ORGAL ORGAWHITE 2000 Opaque polymer:
ORGAL ORGAWHITE 2000 is an ammonia, formaldehyde, and APEO-free Opaque polymer designed for water-based paints and other coatings.
ORGAL ORGAWHITE 2000 is an Opaque polymer
ORGAL ORGAWHITE 2000 is a non-film-forming.
ORGAL ORGAWHITE is polymer emulsion that forms hollow air-filled particles when dried.
When used in paint formulations to partially replace TiO2 and other extenders, Orgal Orgawhite 2000 acts like a fine-particle inorganic extender, spacing the TiO2 particles.
This improves the efficiency of TiO2.
ORGAL ORGAWHITE 2000 has a very low surface area, and the binder demand is very low.
This allows the paint formulators to work at higher pigment volume concentrations.
Utilizing the benefits of the Orgal Orgawhite 2000, the paint formulation cost could be reduced without reducing the performance.
Alternatively, the paint performance could be improved without increasing the cost.
Handling And Storage of Opaque polymer:
Containers should be well sealed to prevent water evaporation and skin formation and ensure safe storage of this emulsion.
The emulsion must be stored between 5-25°C for 12 months, and freezing must be avoided.
Keeping the emulsion under slow and/or intermittent agitation is strongly advised.
Orgal Orgawhite 2000 should not be in contact with any glycols glycol derivatives or aromatic solvents during storage.
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 Opaque polymer 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.
Health and Safety of Opaque polymer:

Before using Opaque polymer, consult the Material Safety Data Sheet (MSDS/Safety Data Sheet (SDS)) for details on product hazards, recommended handling precautions and product storage.
