UV Curing

Q&A: Can you comment on surface cure and factors affecting it?

by

By R.W. Stowe, UV applications engineering consultant, Heraeus Noblelight America LLC It is generally accepted that short-wavelength UV has a major influence on surface cure, but the photochemical mechanisms are a combination of the effects of exposure, composition and optical properties. The most common symptom of a deficiency of surface cure is a tacky, sticky or greasy … [Read more...] about Q&A: Can you comment on surface cure and factors affecting it?
