  1. 1. Contact Allergy to Epoxy Resins of the Bisphenol F-type

    Författare :Ann Pontén; Yrkes- och miljödermatologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thin-layer chromatography; occupational dermatitis; isomers; bisphenol F; bisphenol A; DGEBF; DGEBA; epoxy resin of the bisphenol F-type; Epoxy resin; contact allergy; Dermatology; venereology; Dermatologi; venereologi; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

    Sammanfattning : Epoxy resins based on bisphenol A are well-known contact allergens and often cause occupational contact allergy. The most important allergen is the monomer diglycidyl ether of bisphenol A (DGEBA). LÄS MER

  3. 2. 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

  4. 3. Compression-moulded and multifunctional cellulose network materials

    Författare :Sylvain Galland; Lars Berglund; Naceur Belgacem; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compression-moulding; cellulose fibre; nanocomposite; magnetic nanoparticle; epoxy; UV curing; oxygen barrier;

    Sammanfattning : Cellulose-based materials are widely used in a number of important applications (e.g. paper, wood, textiles). Additional developments are suggested by the growing interest for natural fibre-based composite and nanocomposite materials. LÄS MER

  5. 4. Epoxides as Contact Allergens - Formation, Sensitising Potency and Structure-Activity Relationships

    Författare :Ida Belogorcev Niklasson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Allergic contact dermatitis; Autoxidation; Bioactivation; Cinnamic alcohol; Diglycidyl ether of bisphenol A DGEBA ; Epoxide; Epoxy resin; Local lymph node assay; Polymerisation; Peptide reactivity; Prehapten; Prohapten; Sensitisation; Skin; Structure-Activity Relationship; Thermogravimetric Analysis;

    Sammanfattning : Chemicals in our environment with which we have repeated skin contact can cause skin sensitisation (contact allergy). To trigger an immune response a compound (hapten) must be able to penetrate the skin, where it needs to be reactive enough to bind to proteins and form immunogenic complexes that are recognised as foreign.

  7. 5. Resin transfer moulded composite materials : processing, structure, property relationships

    Författare :J. Anders Holmberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : This thesis contains analysis of the performance of polymer composites manufactured by resin transfer moulding (RTM). The thesis consists of six papers, where the first two deals with the tensile strength of composites reinforced with randomly oriented glass fibres, which still is the most common reinforcement in RTM manufacturing.
