| Résumé : |
There has been considerable growth in the production of prepainted steel over the past decade. This has been due to the increased usage of prepainted steel products in the construction and domestic appliance industries and a recognition by the automotive manufacturing industry of the benefits of prepainted steels, such as Durasteel and Bonazinc. The coil coating industry is, however, under increasing pressure from environmentalists who question the manufacture, content and recyclability of prepainted steel. The major areas of concern are the levels of solvents used in current coil coating paints, the continued use of chromates in pretreatments and primers and the recyclability of halogen-containing (PVC, PVF2) prepainted steels. The European steel industry must respond positively to these environmental pressures if it wishes to maintain and expand its coil coating operations.
Radiation curing has a large potential as a future processing technology for the production of prepainted steel strip. This technology is currently widely used throughout the plastic, paper and wood-coating industries where it shows a number of environmental advantages over conventional thermal curing. |
| Note de contenu : |
- PRINCIPLES OF RADIATION CURING
- CURING MECHANISMS
- THE CHEMISTRY OF RADIATION CURING : acrylate systems - oligomeric (resinous) reactive material - diluents - non-reactive diluents - reactive diluents - adhesion promoters
- EXPERIMENTAL PROGRAMME : raw materials - electron beam curing unit (EBCU) - coating development - addition of pigmentation
- DETERMINATION OF DEGREE OF CURE OF COATING BY FTIR : unpigmented coating - pigmented coating - investigation of heat aging phenomenon - adhesion of EB curable coating to thermally cured topcoats - corrosion testing
- ACCELERATED WEATHERING OF COATING : non-topcoated samples - topcoated panels
- EXTERIOR WEATHERING OF COATING : non-topcoated panels - polyester topcoated panels
- EFFECT OF PROCESS VARIATION ON PERFORMANCE OF COATING : FTIR estimation of cure
- MODIFICATION OF COATING : reduction of gloss by the addition of matting agents - addition of plasticers |
