Résumé : |
Today's environmental regulatory climate is mandating a complete transformation of the industrial coatings market. Low solids solvent-borne chemistries are vanishing rapidly. Water-borne and powder technologies are experiencing surprisingly high rates of growth. In particular, solvent-borne coating applications that can be accomplished with water-borne resins are rapidly moving toward this direction, even if they to do at somewhat higher costs.
Still,parts of the solvent-borne industrial coatings market continue to grow. In particular, both epoxy and polyurethane technologies are growing handsomely, principally at the expense of lesser chemistries such as alkyds of nitrocellulose. The higher performance sectors of the industrial polyurethane coatings market such as automotive and industrial maintenance coatings are projected to grow better than 5% per year.
Higher solids polyurethane systems are inherently more complicated to work with than their conventional solids counterparts. Their components are in more ultimate contact with each other xhich means higher viscosities and greater difficulties in spraying. It also means that these higher solids urethane coatings are much less tolerant to moisture contamination, either in the form of wet pigments or humid application environments. |
