ExactaCoat™ Laboratory Coating System
Precision Thin Film Coating for Research and Development
The ExactaCoat™ is Sono-Tek’s most versatile laboratory coater. It’s a fully programmable, benchtop coating system designed for R&D, process development, and low-volume production. Engineered with Sono-Tek’s advanced ultrasonic spray nozzle technology, the ExactaCoat delivers uniform, repeatable thin-film coatings with micron-level precision across a wide range of substrates.
Whether you’re working with aqueous solutions, polymers, nano-materials, or active ingredients, the ExactaCoat gives you total control over your coating technology — from film thickness to spray width and deposition rate.
With more than 1,000 Sono-Tek coating systems installed at universities and research institutions worldwide, the ExactaCoat is a proven, trusted platform for laboratory coating and process development.
Flexible Design for Every Laboratory
Compact, quiet, and fully enclosed, the ExactaCoat laboratory coater brings production-quality performance to the lab bench. Its modular architecture makes it easy to configure for your specific coating application — from thin film applicators to abrasion-resistant coatings on advanced nano-materials.
The enclosed design also provides a clean, contained coating environment, ensuring safe operation and minimizing operator exposure to solvents or fine particulates.
Key Features:
- Compact benchtop coater with 400 × 400 × 100 mm work area
- Precision servo-driven 3-axis motion control
- Windows®-based software with image import and teach pendant
- Non-clogging ultrasonic spray system with stainless steel and titanium construction
- Adjustable coating thickness and coating width
- Ideal for high-temperature and low-flow rate coating applications
- Safe, fully enclosed design for operator protection and cleanroom compatibility
Advanced Ultrasonic Coating Technology
At the heart of the ExactaCoat is Sono-Tek’s ultrasonic atomizer technology — converting liquids into fine, uniform droplets for superior film formation.
This process reduces waste, improves transfer efficiency, and minimizes overspray, enabling high-quality coatings that are consistent and environmentally responsible.
Ultrasonic nozzle options:
- AccuMist™ – narrow, bow-shaped pattern for precise line coatings
- MicroMist™ – ultra-fine, cylindrical pattern for micro-scale coatings
- Vortex™ – conical pattern for uniform thin films
- Impact™ – fan pattern for wide-area coverage
Each nozzle delivers repeatable results, making it perfect for applications requiring consistent micron-level coating thickness and controlled surface finishes.
Optional Modules and Process Enhancements
Enhance your laboratory coating equipment with customizable options designed for flexibility and control:
- Heat and / or vacuum plate (up to 150 °C) for rapid drying and high-temperature curing
- Plasma/Corona surface treatment for improved adhesion
- MicroFlow recirculation pump or ultrasonic dispersion pump for stable suspensions
- Integrated camera vision and laser pointer for precise alignment
- Inert or low-oxygen atmosphere with real-time monitoring
- Compatible with compressed air or inert gas environments
