Ultra-Thin Coatings

Ultra-thin coatings are essential in various applications, including PCBs, as they offer superior protection against moisture, corrosion, and wear, while also enhancing thermal management, reducing friction, and enabling advanced technologies in fields like electronics, automotive, and medical devices.

A fast, easy to apply & sustainable coating alternative

Ultra-thin coatings are only around 1 micro thick but provide sufficient protection against unwanted influences from the environment. Due to the very low surface energy of the dried coating, it repels moisture, water, oil, dust, solvents and other chemical substances.

The low viscosity of the wet coating flows easily into the narrowest spaces, making sure no surface stays unprotected. They can be applied by dipping, spray or selective spray systems.

Advantages of using ultra-thin coatings

• fast & easy process as it can be applied by dipping and dried at room temperature in a few seconds
• non-flammable
• very sustainable as low toxicity, low GWP, no ozon depleting.
• masking can be in most application reduced or even avoided
• space and weight saving
• cost efficient solution as only little product is used to protect a certain surface
• limited investment needs, even for low volume production quantities
• no impact on transmission of Radio Frequencies (RF)
• no loss of light emissions or color changes when coating LED’s

Our products, TUW-2704 and TUW-1710, offer a simple, efficient, and low-cost solution—just soak the circuit board for 3 seconds to achieve waterproof protection, delivering precision performance for specialized electronics applications.
