Abstract:
A composition comprising a blend of;A. an epoxy functional compound selected from the group consisting of polyglycidyl ethers, glycidyl ether of phenol formaldehyde polymers with a molecular weight of between 350 to 10000; diglycidyl esters of polycarboxylic acids, diglycidyl esters of methacrylic acid; epoxidized oils, cycloaliphatic epoxy compounds and triglycidyl isocyanurate; B. a carboxy functional compound selected from the group consisting of a di- or polycarboxylic acid, an acrylate, a polyester, a di- or poly-anhydride and an acrylic anhydride; and C. a metal (M) salt of an alkyl acid phosphate wherein the alkyl acid phosphate is: (RO)nâ€”(P&boxH;O)â€”(OH)m, and wherein:a. each R is selected from the group consisting of: i) a C1 to C18 alkyl, cycloalkyl, or aryl; ii) a linear or branched C6 to C18 alkyl substituted with â€”(Oâ€”CH2â€”CH2â€”)o or â€”(Oâ€”CHâ€”CH3â€”CH2â€”)p, wherein o or p is from 1 to 20; and iii) a &bgr;-hydroxyethyl moiety, Râ€²â€”Xâ€”CH2â€”CHâ€”OHâ€”CH2â€”, wherein Râ€² is a C6 to C18 alkyl or cycloalkyl or aryl, X is either â€”CH2â€”, â€”Oâ€” or â€”COOâ€”; b. n+m=3 and n is between 2 to 1; and c. M is Zn or Sn (II) in a mole equivalent of 0.7 to 1.5 moles per mole of alkyl acid phosphate.
