Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : An alternative chemistry of UV curable powder coatings is described, in which unsaturated polyesters having maleic/fumaric reactive double bonds are combinded with rystalline crosslinkers bearing unsaturated reactive groups. Varying the level of crosslinker in the formulation provides control over coating properties. Note de contenu : - Several UV powder chemistries are in use
- Crosslinkers can provide closer control of properties
- Three crosslinkers are synthesised in the laboratory
- Synthesis of pentaspiroglycol diacrylate (PSGDA)
- Pentaspiroglycol diallyl ether (PSGDE) - a novel compound
- Synthesis of zinc acrylate
- Crosslinking properties are evaluated
- DSC measures cure speed and Tg
- UV-FTIR confirms crosslinking reactions
- UV rheology follows viscosity changes during cure
- Crosslinker improves standard polyester coating
- Crosslinker conrols speed and degree of final cure
- Fig. 1 : UV-DSC results for different crosslinkers and addition rates
- Fig. 2 : UV rheology results for blend C (open markers) and blend G (filled markers)

Revêtement autopolissant
Revêtements antisalissures:Peinture antisalissuresIndex. décimale : 667.9 Revêtements et enduits Résumé : Bio-fouling on ship hulls is prevented by the use of antifouling paints. Anti-fouling has various mechanisms of which self-polishing types is receiving a great deal of attention world wide. The progressive abandonment of TBT self-polishing technology all over the world has led to the necessity of exploring new TBT-free i.e. environmentally safe horizons. The new metal-acrylate TBT-free systems are finding a new insight in this field where such coatings have found to be lasting for around 5 years.
The foul release systems are the most attractive environmentally since they do not use biocides. Although they are considerably more expensive, they are now being used on fast vessel type, which are able to exploit the smoothness & that this technology will become increasingly important for control of fouling in the 21st century.Note de contenu : - THE SUCCESS OF TBT IS DUE TO FOLLOWING FACTORS
- REQUIREMENTS FOR AN OPTIMAL ANTI-FOULING COATING : Alternatives to TBT-free coatings - Foul-release coating advantages/disadvantages - Tin-free self-polishing co-polymer (SPC) - Metal-acrylate TBT-free self polishing coatings (Cu-, Zn-Sl-Acrylate system) - Ionic exchange mechanism in zinc acrylate system (latest technology) - Zinc acrylate copolymers - Advantages of self-polishing coatings
