Universal Photonics manufactures and distributes over 300 different formulations of specialty polishing pitches to meet the exacting demands of the world’s leading contact lens manufacturers. All blends contain the highest quality polishing compounds and surface quality modifiers.

CONTACT LENS POLISH

X-PAL	Soft, fluffy, white polishing powder manufactured under closely controlled standards. Extremely fine particle size (below 1/1000 millimeter). Used for base and power curve polishing, and peripheral areas of methacrylate and copolymer base contact lenses.
ALOX 722	High-density aluminum oxide (99.9% pure) designed for critical surfacing requirements. Processed using state of the art calcination techniques resulting in a closely controlled particle distribution and complete conversion to the alpha phase.
ALOX 721	Finely graded alumina based material with an average particle size of 1.2 microns. Excellent for all types of RGP work.
KONTAX 601	Alumina based and specially formulated to polish contact lenses. Used in contact lens labs for polishing both hard and soft contact lenses.

DEFOAMER

UNIVERSAL X-DEFOAMER
For use with all polishing powders. A water-soluble polishing extender that controls foam associated with any polishing operation. Applications are found in circulating systems;
starting dilution rate is 2-3% maximum 15%.

SOLVENTS

UNI-CLEAR SOLVENT
        A biodegradable minimally flammable safely solvent which can be used for a wide variety of general purpose cleaning applications. Especially good for removal of pitch and wax residues
        in ultrasonic cleaners. Avoids the dangers associated with normal hydrocarbon solvents. Must be tested on lens materials to determine suitability.

CONTACT LENS SOLVENT
       Fast, safe and economical. Excellent for complete removal of pitch from both lenses and blocks. Faster than similar solvents on the market, not harmful to the skin.

EVERFLO

Suspension agent to increase polishing efficiency and reduce harmful agglomerations. Excellent for all polishing slurry operations.

POLISHING MATERIALS

UNI-V1 Polishing Material- Soft white-flocked polishing pad material finely napped flock - produces excellent results. Available in pressure sensitive form.

UNI-CLOTH Polishing Material - Special silk polishing material with microscopic structure of distributed fibers. Used where strength of pad is a factor.
