1. 1. Thermally cured coil-coatings utilizing novel resins and fatty acid methyl esters as reactive diluents

   Författare :Katarina Johansson; Mats Johansson; Rolf van Benthem; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coatings; Coil-coatings; Thermal cure; Reactive diluents; Fatty acids; Transesterification; Hyperbranched polyester resins; Film properties; Polymer chemistry; Polymerkemi;

   Sammanfattning : Solvent-borne thermally cured coil-coating resins contain large amounts of volatile organic solvents in order to obtain suitable flow for film application. This work describes how the expensive and environmental hazardous volatile organic solvent content of a solvent-borne thermally cured polyester/melamine coil-coating system can be reduced by introduction of fatty acid methyl esters (FAMEs) as reactive diluents and modification of the polyester binder resin.

   Sammanfattning : Coil coatings are durable  organic coatings used to protect metal sheets from corrosion and improve their aesthetic properties. Because of their extensive use, coil coatings have long been of interest for industrial and academic researchers. LÄS MER

4. 3. Fatty acid methyl esters as reactive diluents in solvent-borne thermally cured coil-coatings

   Författare :Katarina Johansson; Mats Johansson; Mats Jonsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fatty acids; Reactive diluents; Coatings; Thermal curing; Transesterification; Film properties; Polymer chemistry; Polymerkemi;

   Sammanfattning : This work describes how a fatty acid methyl ester (FAME) derived from a vegetable oil can be introduced as reactive diluent in a solvent-borne thermally cured coil-coating system. The evaluated reactive diluent, rape seed methyl ester (RME), has been evaluated both in a fully formulated clear coat system and via model studies. LÄS MER

5. 4. Exploring fatty acid derivatives from renewable resources as raw materials for coating applications

   Författare :Samer Nameer; Mats Johansson; Mats Martinelle; Dean Webster; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epoxy; vegetable oils; birch bark; thermoset; bio-based; fatty acid; renewable resources; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : In the work presented herein, epoxy fatty acid derivatives were explored in the formation of thermosets for coating applications. The epoxy fatty acid derivatives were obtained from renewable resources such as birch tree bark and epoxidized linseed oil. LÄS MER
