Understanding the curing of resins and inks by radiation The curing of resins and inks by light energy can be traced back many centuries to Ancient Egypt when resin-soaked mummification wrappings were cured by sunlight.  In 1815, the world saw the first photoengraved printing plate, and for the following 150 years many photochemical reactions have made their marks on history, but a commercial radiation-curing process did not evolve until the...

Proprietary infrastructure coating and repair polymer utilizing recycled tire technology Infra-Gard PK-4200 is a unique polymer coating and repair system that is extremely tough, corrosion resistant, durable and easy to apply.  It incorporates 100% recycled tire polymer that is cryogenically ground, and delivers superb physical performance properties.  In addition, as a “green” formulation utilizing recycled tire compound, it helps to protect...

An international manufacturer of specialty radiation shielding products retained Princeton Keynes to research and identify eco-friendly alternatives to lead for radiation protections. (Global Partners in Shielding, Inc. headquartered in Passaic, New Jersey wanted to find an alternative to lead shielding for certain applications.) Candidate technologies needed to provide the same radiation protection as lead with significantly reduced health and...

An innovative international company developed a unique method for industrial water treatment utilizing a specialized aggregate.  However, they needed a “green,” completely toxicologically benign binder technology to use for the aggregate product.  The binder needed to work synergistically with the aggregate, withstand prolonged immersion and flow rates, and produce no leachate or contaminants that could impact final water quality.  Princeton...

A large wood products manufacturing company commissioned a research program with Princeton Keynes to identify alternative wood preservation treatments for its products.  The client wanted an environmentally friendly alternative to the standard heavy-duty wood preservation approaches such as chromated arsenicals, pentachlorophenol, and creosote.  Of course, the client needed a solution that would maintain optimum preservation performance in...
