Non-cryogenically generated nitrogen atmosphere for radiation curing

摘要

The present invention discloses an improved method of producing a low-cost, nitrogen-based inert atmosphere suitable for radiation curing of resins, coatings, etc. from non-cryogenically generated nitrogen. According to the disclosed method, residual oxygen present in non-cryogenically generated nitrogen is converted to either moisture or a mixture of moisture and carbon dioxide by reaction with a reducing gas in a catalytic reactor prior to using the nitrogen-based atmosphere for radiation curing of moisture insensitive materials such as resins and coatings.
