Recent environmental regulations such as the Montreal Protocol and Clean Air Act have had a significant impact on both coating materials and application methods, particularly with regard to control of Volatile Organic Compounds (VOCs) and ozone depleting chlorofluorocarbon (CFC) compounds.
VOCs are the primary concern, as they react in the atmosphere to form ground-level ozone (or smog). Both VOCs and CFCs have been extensively used as solvent carriers. Manufacturers and suppliers of conformal coating materials have responded by developing non-solvent based coatings and environmentally acceptable methods of application, curing and removal.
In addition.
....there is increasing concern over the severe adverse effects of long-term exposure to hazardous solvents such as Xylene and Toluene, both regularly used in conformal coatings.
Indeed, Toulene has recently been reclassified at a higher hazard rate (now a class 3 carcinogen, rating to come into force October 2005) and changes in legislation will not be far behind.
The recent ‘lead-free’ move has demonstrated how important it is to anticipate and allow for these major changes to the way our industry operates, if we are to remain competitive and profitable.
