Rev. D (3/21) 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 Tested • UL94 V-0 Rated • Crystal Clear & Glossy Finish • UV Indicator for Black Light QC Inspection • MEK, Toluene & Xylene Free • Adjustable spray head (Aerosol) Applications Electronic Assemblies for... • Automotive • Aviation • Consumer Electronics • Appliances • Industrial Meters & Control Usage Instructions For industrial use only. Read SDS carefully prior to use. Before applying Turbo-Coat™ conformal coating, clean circuit boards to remove contamination and allow to dry. Cleaning is recommended for optimal adhesion, and may be performed with Techspray G3, E-LINE™ and Precision-V defluxers. Spray Application: Apply top to bottom, allowing coating to flow evenly around components. Repeat application 3 additional times from varying directions to prevent component shadowing. 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.

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 coating process. After application, cured Fine-L-KoteTM may be removed using Techspray Conformal Coating Removal Pen (2510-N or 2510-P). 800-858-4043 • www.techspray.com Rev. D (3/21) Page 2 of 4 Turbo-Coat Acrylic Conformal Coating Product# 2108 Thinning/Removal Techspray® coatings can be thinned to meet production requirements using Conformal Coating Thinner (2105). Conformal Coating Remover (2510) is also available for rework and repair, although coating is often just burnt through in the soldering process for spot repairs. Techspray® coatings contain Opti/Scan to allow quality control inspection of coverage and evenness of the coating on a PCB. A coated board can be passed under a standard, low-cost UV (black) light, and the coated areas glow. The brighter the glow, the thicker the coating.

Dilution will also change the cure profile. 149°F / 65°C is recommended as the best accelerated temperature to optimize leveling, providing the smoothest possible finish. A faster cure may be achieved, but should be thoroughly tested first.
