Dow Corning Launches Silicone Coatings for Latex Catheters

Published on 2005-09-14. Author : SpecialChem

Dow Corning, a leading global supplier of silicon-based solutions for the healthcare industry, has unveiled a two-part silicone elastomer dispersion system to coat latex catheters. Launched by Dow Corning at MEDTEC China 2005 (Shenzhen), this safe and cost-effective silicone application addresses key design and performance issues, simplifies manufacturing processes, and improves catheter properties, providing benefits to both manufacturers and patients.

Silicon-based materials featured at MEDTEC China include Dow Corning® Q7-2630 Dispersion and Dow Corning® Q7-2640 Catalyst, which are combined to form the silicone elastomer dispersion. A third component, Dow Corning® Q7-2650 Fluid, acts as a solvent for diluting the dispersion. The versatile, easy-to-use coating may be applied by dipping, spraying, or brushing, and forms a tack-free surface in approximately 30 minutes, depending upon environmental conditions.

Physical properties, biocompatibility, and easy processing translate Dow Corning silicones into performance-enhancing solutions for medical-device applications. Patients benefit from the smooth surfaces of silicone coatings, which reduce friction upon insertion, minimize pain and irritation, and may decrease harmful incrustation on latex catheters. In addition, the use of silicone as a coating rather than as a primary material makes this approach cost efficient for manufacturers.
