Résumé : |
The automated application of sealants and adhesives in settings such as automotive production requires that predictable, reproducible quantities are applied, and that they flow properly and remain in place during the final setting period. In the printing industry, lamination of plastic films is done on specialized high-speed machines that require close control of adhesive viscosity. Resins that are applied to fiber textiles and mats to make composite prepregs require exact staging of the matrix resin. |
