CHEMTRONICS TDS # CTSRHV Technical Data Sheet Konform SR High Viscosity PRODUCT DESCRIPTION Konform SR High Viscosity provides maximum coverage where good flexibility is required, or where extreme temperatures can be encountered. This transparent coating provides ideal protection for both rigid and flexible printed circuit boards. Cured coatings are hydrolyticly stable and retain their physical electrical properties after high temperature and humidity exposure. Konform SR High Viscosity will not stress delicate circuit components. Extends component life by protecting against adverse environments Good insulation properties, excellent flexibility Resists moisture, salt, fungus, corrosive vapors, and severe environments Engineered to withstand heat generated by electronic circuitry as well as climatic temperatures Contains a UV indicator for thorough Quality Control inspection TYPICAL APPLICATIONS Konform SR High Viscosity is ideal for applications in: Aerospace Data Communications Instrumentation Automotive Manufacturing Marine Manufacturing Process Control TYPICAL PRODUCT DATA AND PHYSICAL PROPERTIES Usable Temp.

As with any chemical product, product/component compatibility must be determined on a non-critical 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 High Viscosity conformal coatings, clean circuit boards to remove contamination and allow to dry. Cleaning may be performed with Chemtronics Electro-Wash PX, Electro-Wash CZ, or high purity acetone. 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. REMOVAL: After application, cured Konform SR High Viscosity may be removed by soaking in Chemtronics Electro-Wash Two Step, or an aromatic solvent (such as xylene), or a short chain ketone (such as acetone).
