Introduction to Bürkle Roll Coater

The Bürkle Roll Coater is a state-of-the-art roller coating machine designed for precise, uniform application of coatings on various substrates such as wood-based panels, glass, and printed circuit boards. Known for its high efficiency and consistent results, it serves multiple industries including wood finishing, solar glass production, and digital printing protection.

How the Bürkle Roll Coater Works

Roller Coating Process Overview

The roller coating process involves applying a liquid coating material onto a substrate using a series of rollers. The Bürkle Roll Coater uses an applying roller and a doctor roller to control the coating thickness precisely, ensuring uniform coverage and minimal material waste. This method contrasts with spray coating by providing a consistent, predictable layer thickness, essential for high-volume production.

Key Components

- Applying Roller: Transfers the coating material onto the substrate.

- Doctor Roller: Controls the thickness of the wet coating by removing excess material.

- Transport System: Moves the substrate steadily through the coating area.

- Drying Unit: Often includes UV curing modules for rapid hardening of UV-based lacquers.

Applications of Bürkle Roll Coater

Wood-Based Panels Finishing

Bürkle's roller coating machines are widely used for laminating, lacquering, and printing on wood panels. The technology ensures high-quality finishes with both gloss and matte coatings, suitable for furniture and flooring industries.

Solar Glass Anti-Reflective Coatings

In solar glass manufacturing, the Bürkle Roll Coater applies ultra-thin anti-reflective (AR) coatings that reduce light reflection and increase light transmission to solar cells, enhancing module efficiency. The e.a.sy-Coater model achieves wet coating thicknesses of 5 to 15 microns, drying to 100–200 nanometers, delivering flawless, uniform layers critical for solar performance.

Digital Printing Protection

The machine also applies UV-based lacquers to protect large-format digital prints on flexible and rigid materials, improving durability and appearance.

Advantages of Bürkle Roll Coater

- High Precision: Stable machine design with vibration-absorbing cast iron frame ensures consistent coating quality.

- Material Efficiency: Minimizes coating material loss by precise application.

- Versatility: Handles a wide range of materials including wood, glass, composites, cardboard, and foils.

- Customizable Coating Thickness: Adjustable application from thin films to thicker layers (0.1 to 80 mm substrates).

- Integrated Drying: UV curing modules with adjustable power for tailored polymerization.
