Contract Research & Development

Download Research and Development Information Sheet - Spectra scientists' forte is creative problem solving. They are among the world's leaders in photopolymers and photo polymerization. If your business has a product opportunity, but not the technical resources to take advantage of that opportunity, we can turn your potential business missed into new products for your company. 


Photochemistry Contract Research & Development

Spectra Group (SGL) offers world-class expertise and resources for research & development in basic and applied photochemical sciences. Whether your interests involve state-of-the-art photochemistry, problem solving or product development, we offer creative solutions and exceptional resources. SGL has the experience to address various photochemical problems and conduct basic R& D related to novel photochemistries, energy cure, photodegradation, photophysics and other areas. Our expert staff, in close collaboration with the Center for Photochemical Sciences at Bowling Green State University and other universities throughout the world, has access to the finest instruments and facilities to provide an unmatched level of expertise in various areas of photoscience.

Photochemical Research & Development Projects

All R & D photochemical projects are conducted on a confidential basis. Spectra Group seeks to provide its clients with a proprietary or patent position. Spectra Group extends its services to benefit companies both specializing though not skilled in energy cure.

Research and Development performed in support of the energy (radiation) cure and allied industries include:

• Basic research related to energy cure, photodegradation, photophysics
• UV, visible light and EB cure
• Novel photocure processes
• Help with development and introduction of new products (resins, photoinitiators, etc.)
• Custom photoinitiator and resin synthesis
• Formulation development and optimization (enhancing cure and property performance)
o coatings
o adhesives for plastic and metal
o inks
o highly filled materials
o deep cure materials
o thick composites
• Trouble shooting and product improvements
• Assessing feasibility
• Novel, difficult or “next generation” applications
• Specialty cure applications
• Testing and analysis

Below is a representation of the solutions we have provided to a variety of industries.

Case Study #1
Repairing Corrosion In Submarine Ballast Tanks.

Repainting submarine ballast tanks while a ship is in dry dock can be a long process. The environment in a ballast tank is also very aggressive, and the water of the sea is continually circulated in and out so demands on the successful replacement paint are enormous –it must be anti-corrosive, stick vigorously to metal, and not be susceptible to later attack in its environment. 

The main objective of the project was to find such a paint that could be rapidly dried, yet provide the same anti-corrosion protection, and peripherally the color of, the paint original to the surface. At the time this project was begun for the Office of Naval Research, Carderock Laboratories, 2 part epoxy repair paints were in use.

Spectra scientists developed an energy cured repair paint with all of the properties of the 2-part epoxy that would dry in a few minutes as opposed to a week or more. Submarines in which this paint has been applied continue to sail the Pacific, with the paints in continual use for more than 7 years.

Case Study #2
Develop Blood Simulants For Use In Training Raw Military Recruits and Emergency Medical Technicians (EMT)

Nearly 70% of the deaths in combat occur from blood loss incurred in the first few minutes after a wound. Training army personnel for various extreme situations is a critical component of being prepared for combat missions. It is crucial that every participant in combat is trained to stop bleeding and conduct hemorrhage control. At this moment, four out of nine training procedures involve the use of animal blood thus bringing certain biological hazards plus requiring extensive use of live animals. The use of an artificial blood simulant would be a safer and less expensive route for training. That is the target of an on-going Spectra Group contract.

Production of full line of simulant products and first delivery to training centers is expected within a year.

Case Study #3
Optical Lenses For Optometrist’s Office Manufacture Lens With The Speed Of Light.

Preparing a new pair of glasses from the basic stock of lenses held by most optical laboratories is expensive for the customer. Lens pairs from typical optometrists can cost hundreds of dollars even when the patient’s prescription is simple, and more than that for patients whose eyes need more complex corrective devices. In the 3rd world, where these base stocks are not available, patients go without glasses, or use ill-fitting ones perhaps passed down by a relative or friend.  

In collaboration with in a program supported by the Ohio Department of Development, Spectra scientists developed a series of energy curable optical plastic formulations and a device equipped with molds basic to nearly 55 different required visual corrections. With this device, in which pre-polymer formulations are polymerized with light in the shaped mold, an optician can make a set of spectacle lenses in his own shop to meet the correction requirement of a patient and do so in a few minutes. In the 3rd world, one laboratory or optometrist’s organization can hold the basic set of molds, so that the only consumable is the optical lens formulation – the Spectra Group’s Opticast product.
