DEFINITION

Classification: 427/492

Multiple applications of identical radiation energy source to polymerize (e.g., pulse, flash lamp, etc.):

(under subclass 487) Processes wherein the polymerization of the coating is influenced by the duration of intermittently applied identical radiation energy.

(1) Note. For the purpose of classification here and indented subclasses, the term "radiation energy" includes: a. Electromagnetic Radiation (radio wave, microwave, visible, ultraviolet, X -rays, gamma ray, actinic) b. Acoustic Radiation (infrasonic, sonic, ultrasonic) c. Particle Radiation (alpha ray (helium atom, 2 protons + 2 neutrons), beta ray (electrons), electron (accelerated beam), neutron). This list is not intended to be exhaustive and is not limited to the above examples.

(2) Note. Processes for using pulsed discharge devices or flash lamps to achieve polymerization of the applied coating may be found here.
