Biobased Hydroxyl Or Carboxyl Polyester Resins
Abstract: 46s54 222The invention concerns a polyester resin having a linear or branched structure and free of unsaturated fatty acids which is hydroxylated or carboxylated and characterised in that it is made from: a) an acid component comprising: a1) at least one C to C carboxylic polyacid or anhydride a2) at least one C to Ccarboxylic polyacid or anhydride a3) optionally at least one C to C saturated monoacid b) an alcohol component comprising: b1) at least one biobased polyol having a functionality of at least 2 and at least one of the following two polyols b2) or b3): b2) at least one polyol different from b1) having a functionality of at least 2 b3) at least one polyol different from b1) and b2) having a functionality of at least 3. Said resin is more particularly 100% biobased. The invention also concerns a resin solution and a coating composition comprising said resin and the use of same in coatings having a high strength and made from renewable raw materials.
