1、UV Coatings for High Volume Production:Faster.Smaller.Cleaner.IntroductionMy Name:Rich LeonardCurrent Role:Sales Director(U.S.based UV Coatings company)Experience:Thin film coatings and surface treatments-28 years.Education-Materials Science,Metallurgy,Applied TechnologyCareer-Production Manager,Pro

2、cess Manager,Product Manager,and Sales.Purpose at CTT Summit:Increase awareness of sustainable UV cured coatings for the U.S.manufacturing sector.HEATSUNLIGHTUV CUREHOSPITAL395 LEDUV Light/Energy Application DiagramWhat are UV Coatings?DefinitionUnique coatings which cure when exposed to UV light en

3、ergy(instead of heat energy).CompositionOligomers:pre-polymer resin.Monomers:low weight compounds that react with oligomers.Photoinitiators:absorb UV light which initiates reaction.Additives:enhance specific properties.Basic Mechanism1.UV energy penetrates the coating and activates photoinitiators.2

4、.Photoinitiators absorb UV energy and decompose to form reactive radicals or cations.3.The reactive species cause monomers and oligomers to link together forming long polymer chains(polymerization).4.The chain reaction continues until the coating has fully cured.LED or Microwave UV LampUV Coating in
