Composition and Properties of ROPAQUE Opaque Polymer:
ROPAQUE Opaque Polymer is an aqueous solution composed of ammonia gas (NH3) dissolved in water.
The concentration of ammonia can vary depending on the specific application requirements.
ROPAQUE Opaque Polymer is colorless with a strong, pungent odor.
ROPAQUE Opaque Polymer has a density of approximately 0.9 g/mL and is highly water-soluble.
The presence of ROPAQUE Opaque Polymer can increase the pH level of water due to its basic nature.
ROPAQUE Opaque Polymer is important to handle the product with proper precautions as it is highly corrosive and can cause severe skin and eye irritation.
ROPAQUE Opaque Polymer exists only in the form of an aqueous solution.
ROPAQUE Opaque Polymer is prepared by dissolving NH3 in H2O and usually is referred to in industrial trade as aqua ammonia.
For industrial procurements, the concentration of NH3 in solution is normally specified in terms of the specific gravity (degrees Baum′e, °Be).
Common concentrations are 20 °Be and 26 °Be.
The former is equivalent to a sp gr of 0.933, or a concentration of about 17.8% NH3 in solution.
The latter is equivalent to a sp gr of 0.897, or a concentration of about 29.4% NH3.
These figures apply at a temperature of 60 °F (15.6 °C).
Reagent grade NH4OH usually contains approximately 58% NH4OH (from 28 to 30% NH3 in solution).
The reaction mechanism involves the conversion of hydrogen fluoride (HF) to hydrofluoric acid (HF), which reacts with ammonia to form ammonium fluoride (NH4F).
This reaction produces heat and gives off water vapor.
ROPAQUE Opaque Polymer is a weak base, so it will react with any strong acid, such as hydrochloric acid or sulfuric acid, but not with weak acids such as acetic acid or phosphoric acid.
A non film-forming, low-odor synthetic pigment engineered to improve the economics of waterborne coatings.
ROPAQUE Opaque Polymer shows increased light scattering efficiency compared to previous Opaque Polymer products, while maintaining paint performance.
The addition of ROPAQUE Opaque Polymer to paints allows for the formulator to remove TiO2 in a paint while maintaining the same level of dry hiding in the coating.
ROPAQUE Opaque Polymer have a narrow particle size distribution and are similar in size to TiO2 particles.
This allows them to act like ultra fine inorganic extenders, spacing TiO2 effectively and therefore increasing its efficiency as a primary pigment.
Compared to inorganic small particle size pigment extenders, ROPAQUE Opaque Polymer have a very low specific surface area due to their uniform, spherical shape and non porous surface.
The binder demand of ROPAQUE Opaque Polymer is therefore significantly lower, giving the possibility of formulating at higher pigment volume concentrations.
The combined effect of these three product features can be used by paint formulators to either reduce paint cost without negative effect on paint performance, or alternatively, improve paint performance without increasing costs.
Light scattering theory shows that the two parameters most impacting the hiding efficiency are the particle size of the hollow spheres and the void fraction.
The optimum light scattering efficiency is obtained at a particle diameter of roughly 0.40µm.
The innovative process used to manufacture ROPAQUE Opaque Polymer enables an optimum particle size (0.38µm) with a maximized void fraction of 44%.
ROPAQUE Opaque Polymer represents excellent performance for a polymeric opacifying agent.
Like its predecessors, ROPAQUE Opaque Polymer, is a hollow sphere polymeric pigment allowing paint manufacturers to reduce the raw material cost of their formulations with no performance penalties.
ROPAQUE Opaque Polymer maintains the same efficiency and light scattering ability of ROPAQUE Opaque Polymer, with the added advantage of being ammonia free.
In addition to offering very efficient dry opacity properties, ROPAQUE Opaque Polymer offers a wide range of benefits in interior and exterior paint formulations and can be used as a ‘drop in’ replacement for ROPAQUE ULTRA Opaque Polymer.
ROPAQUE Opaque Polymer is a colorless aqueous solution.
Concentration of ammonia ranges up to approximately 30%.
ROPAQUE Opaque Polymer vapors (which arise from the solution) irritate the eyes.
ROPAQUE Opaque Polymer is a colorless, liquid solution with a characteristic and pungent odor.
ROPAQUE Opaque Polymer is ammonia combined with water.
ROPAQUE Opaque Polymer is a compound consisting of nitrogen and hydrogen.
Both ROPAQUE Opaque Polymer and ammonium hydroxide are very common compounds, found naturally in the environment (in air, water, and soil) and in all plants and animals, including humans.
ROPAQUE Opaque Polymer is a source of nitrogen, an essential element for plants and animals.
ROPAQUE Opaque Polymer is also produced by the human body – by our organs and tissues and by beneficial bacteria living in our intestines.
ROPAQUE Opaque Polymer plays an important role in protein synthesis in the human body.
In brief summary, all living things need proteins, which are comprised of some 20 different amino acids.
While plants and microorganisms can synthesize most amino acids from the nitrogen in the atmosphere, animals cannot.
For humans, ROPAQUE Opaque Polymer cannot be synthesized at all and must be consumed as intact amino acids.
Other amino acids, however, can be synthesized by microorganisms in the gastrointestinal tract with the help of ammonia ions.
Thus, ROPAQUE Opaque Polymer is a key player in the nitrogen cycle and in protein synthesis.
ROPAQUE Opaque Polymer also helps maintain the body's pH balance.
ROPAQUE Opaque Polymer, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water.
ROPAQUE Opaque Polymer can be denoted by the symbols NH3(aq).
Although the name ROPAQUE Opaque Polymer suggests an alkali with composition [NH4+][OH−], ROPAQUE Opaque Polymer is actually impossible to isolate samples of NH4OH.
The ions NH4+ and OH− do not account for a significant fraction of the total amount of ammonia except in extremely dilute solutions.
Diluted (1–3%) ROPAQUE Opaque Polymer is also an ingredient of numerous cleaning agents, including many window cleaning formulas.
Because aqueous ammonia is a gas dissolved in water, as the water evaporates from a window, the gas evaporates also, leaving the window streak-free.
In addition to use as an ingredient in cleansers with other cleansing ingredients, ROPAQUE Opaque Polymer in water is also sold as a cleaning agent by itself, usually labeled as simply “ammonia .
ROPAQUE Opaque Polymer may be sold plain, lemon-scented (and typically colored yellow), or pine-scented (green).
