Surface coatings industry solutions

Particle size and particle size distribution are key product quality parameters for the surface coatings industry, impacting directly on the handling properties of the product and the finish achieved. Performance during the application process is strongly influenced by particle size for both toners and powder coatings, as is the clarity of print (for toners) or surface finish (for powder coatings). Manufacturers are typically working to deliver products economically with increasingly narrow particle size distributions; product consistency is a key goal. Off-line particle size measurements play important roles in the development of new products and on-line particle size provides effective control of production processes once the key control parameters have been defined.

	Powder coatings industry solutions Although relatively new, powder coatings have successfully displaced conventional liquid technologies for a range of surface coating applications, primarily because of their environmental credentials. Product consistency is essential for continued market success, and the optimization of multiple production lines, each manufacturing a variety of powders, is a key goal for cost-effective production. Product cross-contamination, minimization of the production of excessive fines and the production of more batches of smaller size and more varied colors are the major concerns of this industry today.


	Toner industry solutions To gain competitive advantage, toner manufacturers increasingly need to tighten control of both particle size and shape as both of these parameters have a direct impact on print quality. At the same time, the falling price of toner is forcing manufacturers to minimize the variable costs associated with production. These challenges are being addressed by improving the control of conventional processes and by developing new polymerization-based manufacturing technologies. Particle size and shape analyzers are invaluable in the development of new processes and for quality control. On-line systems have a key role to play in tightening process control and improving production efficiency.


	Paints and pigments Particle size and rheological properties govern many key properties that are important to the coatings industry. For example, flocculation, hue/tint strength, hiding/transparency, dispersability, stability, gloss/flatting and film appearance, viscosity and weather resistance are some examples.
