CHEMTRONICS TDS # Technical Data Sheet CTSR Konform SR PRODUCT DESCRIPTION Konform SR provides maximum flexibility for extreme temperatures. This transparent coating provides ideal protection for both rigid and flexible printed circuit boards. Cured coatings are hydrolytically stable and retain their physical electrical properties after high temperature and humidity exposure. Konform SR will not stress delicate circuit components. Konform SR resin meets MIL-I-46058C, Type SR. TYPICAL PRODUCT DATA AND PHYSICAL PROPERTIES Usable Temp. Range of Cured Coatings Tack Free Time (-85F to 390F) (-65C to 200C) 15 min.

As with any chemical product, product/component compatibility must be determined on a noncritical area prior to use. Performance Moisture Resistance Removability Ease of Repair Flexibility Adhesion Abrasion Resistance Solvent Resistance Excellent Excellent Excellent Excellent Excellent Fair Good USAGE INSTRUCTIONS For industrial use only. Read MSDS carefully prior to use. Before applying Konform SR conformal coatings, clean circuit boards to remove contamination and allow to dry. Cleaning may be performed with Chemtronics Flux-Off products. SPRAY APPLICATION: Apply top to bottom, allowing coating to flow evenly around components. Rotate PCB 90 and repeat application. Rotate and apply coating two additional times, then allow board to cure. If additional thickness is desired, apply additional coatings. When using liquid spray with automatic dispensing equipment, adjustments may be required in application rate and viscosity. DIP APPLICATION: Using automatic equipment or hand immersion technique, slowly immerse PCB into the coating and remove slowly. Use an average rate of approximately 1 foot per minute. After allowing the board to cure, process may be repeated to achieve desired thickness. BRUSH APPLICATIONS: Evenly apply coating to areas desired at thickness required. Allow time for curing before reapplying to achieve a thick coating. Use Chemask to protect components during conformal coating process. After application, cured Konform SR may be removed by soaking in Chemtronics Electro-Wash Two Step. AVAILABILITY CTSR-12 10 oz.
