polycarbonate (PC)
a thermoplastic material derived from the reaction of aromatic dihydroxy compounds with carbonic acid with high impact strength, low water absorption, heat and moisture resistant, and good electrical and optical properties.
Calcium Carbonate: In alkaline paper making, the primary filter; limestone or chalk.
Ammonium carbonate - . 80 g
Water 1 oz.
To develop the plate 6 minims of No. 1, 3/4 drachm of No. 2, and 3 drachms of No. 3 are mixed together and made to flow over the plate after washing the preservative off under the tap.
Potassium carbonate - highly soluble alkaline accelerator used in most general purpose and print developing solutions.
Potassium chloride - chemical used in some bleaches and sensitizers.
Potassium citrate - chemical used in blue and green toners.
Construction
Polycarbonate resin with glass fibre on aluminum chassis
Magnesium alloy body ...
See SODIUM HYDROXIDE, SODIUM CARBONATE, SODIUM META- BORATE, and SODIUM BORATE. ACHROMATIC COLORS-Colors perceived as having no hue (white, black, gray, and silver). ACHROMATISM -The absence of chromatic aberration.
One day I made up a developer solution containing metol, sulfite, carbonate, and bromide, and bubbled air through it for several hours to oxidize a large part of the metol.
Borax is recommended for the finest grain and lowest contrast, Sodium Metaborate for increased contrast accompanied with increased grain, and Sodium Carbonate for the highest contrast but with the greatest grain.
This rugged housing is constructed of ABS and polycarbonate plastic for corrosion resistance and lightweight. Designed with flexibility in mind the housing will accept all of the current line of conversion lenses for the MMIII camera.
As far as Kodak Lens Cleaner, I read from the bottle that it is water and ammonium carbonate, which is different than household ammonia (ammonuium hydroxide).
Not only are the dyes a factor but the stability of the polycarbonate plastics, the environmental storage conditions (eg: abrasion, water vapour, airborne pollutants such as sulphur, and shock can all degrade CDs), ...
An extremely tough polycarbonate plastic, usually transparent, used to make underwater housings. 'Lexan' is a trademark of the General Electric corp.

For instance, you can get a fully featured professional laptop like the tiny, lightweight (magnesium frame), durable (rubber mounted hard drive) and durable (case made of the same polycarbonate as my motorcycle helmet) Apple 12" G4 iBook for about ...
Accelerants are an akali, commonly sodium or potassium hydroxide, sodium carbonate, kodalk, or borax. Yes, that is the same stuff in the box at the grocery with that twenty-mule team on it.
This is because manufacturers cannot make and sell them in such large numbers. A commercially available polycarbonate SLR camera housing is almost the same price as a Nikonos V with a 35 mm lens.
A chemical ingredient of film or paper developers that's often referred to as an activator and speeds up the developing agents. It's usally an alkali such as sodium carbonate, borax or sodium hydroxide.
