Rev. A (05/18) Page 1 of 4 Turbo-Coat Acrylic Conformal Coating Product 2108 Product Description TurboCoat Acrylic Conformal Coating is designed to speed up board production throughput without additional investment of expensive UV systems or other capital equipment. Conformal coating cure time is often considered a production bottleneck for PCB assembly operations. TurboCoat dries tack free in 3 minutes, allowing manufactures to handle boards in 1/3 the time of the leading acrylic coating Full cure can be achieved as quickly as 10 minutes with elevated temperatures. Features / Benefits Fastest Cure Dry to Touch in 3 Minutes Faster Throughput without Capital Investment Thick Coating One-Pass Application Fast & Easy Rework & Repair IPC-CC-830 & MIL-I-46058C Tested UL94 V-0 Rated Crystal Clear & Glossy Finish Typical Product Data and Physical Properties UV Indicator for Black Light QC Inspection MEK, Toluene & Xylene Free Physical State: Liquid Adjustable spray head (Aerosol) Odor: Characteristic odor Color: Clear, colorless Applications Percent Volatile: 93.4 at 25C (77F) Electronic Assemblies for...

Read SDS carefully prior to use. Before applying Viscosity 1: 10 to 20 Centipoise at 25C (77F) Turbo-Coat conformal coating, clean circuit boards to remove VOC: 33.240% by weight contamination and allow to dry. Cleaning is recommended for optimal Shelf life: 2 years adhesion, and may be performed with Techspray G3, E-LINE and Precision-V defluxers. Chemical Components Spray Application: Apply top to bottom, allowing coating to flow evenly Acrylic Polymer (non-hazardous) around components. Repeat application 3 additional times from varying directions to prevent component shadowing. Then allow board to cure. If n-Propyl acetate CAS 109-60-4 additional thickness is desired, apply additional coatings. When using Acetone CAS 67-64-1 liquid spray with automatic dispensing equipment, adjustments may be n-Heptane CAS 142-82-5 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 Application: Evenly apply coating to areas desired at thickness required. Allow time for curing before reapplying to achieve a thick coating. Use WonderMASK to protect components during conformal TM coating process. After application, cured Fine-L-Kote may be removed using Techspray Conformal Coating Removal Pen (2510-N or 2510-P). 800-858-4043 www.techspray.com Rev.
