摘要:
The present invention relates to a composition comprising an active ingredient soluble in water at 20°C at no greater than 10 g/L, and a hyperbranched polyester linked to a polar polymer comprising a polycondensate or a polymer comprising ethylene unsaturated monomers. The invention further relates to said hyperbranched polyester and to a method for the production thereof. The invention further relates to the use of the hyperbranched polyester for solubilizing the active ingredient in aqueous compositions.
摘要:
The present invention is directed to a coating composition for producing an adherent coating on a resinous substrate wherein the coating composition comprises a crosslinkable component comprising a polyol, a telechelic diol, and a crosslinking component. The crosslinking component comprises isocyanate functional molecules and the ratio of isocyanate functional groups to hydroxy functionality is in the range of from 0.1:1 to 0.8:1. The present invention is also directed toward a method of producing an adherent coating on a resinous substrate using the coating composition.
摘要:
An urethane coating resin composition comprising as essential components (A) an isocyanurate-type polyisocyanate derived from hexamethylene diisocyanate and containing at least 65% by weight of a mononuclear compound and (B) an acrylic polyol having a number-average molecular weight of 5,000 to 25,000 and a hydroxyl value of 40 to 160.
摘要:
Disclosed are aqueous coating compositions comprising at least one hydroxyl-containing compound (A), at least one compound (B) having isocyanate groups and also having hydrolyzable silane groups, and at least one catalyst (C) wherein the compound (B) has 10 mol % to less than 90 mol % of at least one structural unit (I) -N(X-SiR''x(OR')3-x)n(X'-SiR''y(OR')3-y)m(I) Where R'=hydrogen, alkyl or cycloalkyl, X, X'=linear and/or branched alkylene or cycloalkylene radical having 1 to 20 carbon atoms, R''=alkyl, cycloalkyl, aryl or aralkyl, n=0 to 2, m=0 to 2, m+n=2, and x, y=0 to 2, and more than 10 to 90 mol % of at least one structural unit (II) -Z-(X-SiR''x(OR')3-x) (II), where Z=-NH-, -NR-, -O- or -S-, where R=alkyl, cycloalkyl, aryl or aralkyl, and x, X, R' and R'' have the definition indicated for formula (I).
