| Résumé : |
The authors set out to investigate the various possibilities of UV- and visible light reticulation of thick, pigmented media usable in the paint industry. A new system, polymerizing paints of various colours at the thicknesses required by the household furniture industry, was worked out (> 100 μm). This is a one step process, with a working speed of 10 ml min, involving four 80 W/cm lamps. This is the only present-day system capable of working under industrial conditions. |

2) Procedure (a. Calculating the maximum thickness of the polymererized layer of a formulation for a given illumination time - b. Estimating the illumination time required for the polymerization of a layer whose thckness was fixed beforehand - c. Drying unit)
- Polymerization prospects of a pigmented coating : 1) First generation initiators - 2) Effectiveness of the TPO-1184 system - 3) Advantages and limits of use of TPO in a pigmented medium
- Polymerization reactions sensitized in the presence of dyestuffs
- Hybrid initiating systems in acrylate oligomers : 1) Association of a radial initiator with an organometallic compound - 2) Association of a radical initiator with a peroxide
- The new system : Effectiveness in pigmented media : 1) Difference in reactivity according to pigment colour (a. On the labotary scale - b. On the industrial scale) - 2) Differences in reactivity according to the nature of the polymer |
