Valspar Sourcing has been granted a pat-ent for a method of making a coating composition comprised of reacting the following components to form a coating composition:a first component A,com-prised of:approximately 20%weight to 90%weight,based on the total weight of the composition,of an unsaturated polyester resin,wherein the unsaturated polyester is comprised of allyl ether func-tionality,1%weight to 50%weight:an alkoxy(meth)acrylic functional mono-mer,wherein the functional monomer is selected from di and tri(meth)acrylic functional compounds with 8 to 16 eth-oxy or propoxy groups along a backbone and a thermoplastic compound contain-ing active hydrogen groups,wherein the thermoplastic compound is selected from cellulose resins and cellulose derivatized resins;and 0.1%weight to 3%weight of least one metal drier,wherein the metal drier is a metal salt of an organic acid,and wherein the metal is comprised of Co,Mn,Pb,Ce,Zr,Ca,Zn,Bi,Cu,Cr,Li,K,Ni,Mg and mixtures and combina-tions thereof,and a second component B,comprised of 0.5%weight to 5%weight of at least one organic peroxide;wherein the coating composition is substantially free of any of formaldehyde,isocyanate and styrene.
