R&D Laboratory Coating Tester

The R&D laboratory coating tester drives the coating head via a motor to move uniformly over the substrate, applying the coating material evenly at a set thickness onto the surface. It is used to simulate production processes, test coating uniformity, and evaluate drying performance, making it suitable for experimental coating on materials such as paper and film.
Selection
When selecting, consider the compatibility of the coating speed range with the sample size, ensure the coating thickness adjustment accuracy meets experimental requirements, assess substrate compatibility including material and thickness, opt for a user-friendly and intuitive operation interface, and evaluate the ease of equipment maintenance as well as the responsiveness of after-sales service.

How to choose a laboratory coater? Which one should you buy: wire bar, scraper, or slot die?
This article introduces three methods for selecting laboratory coating machines: wire bar coating is suitable for low-viscosity coatings, offering low cost and simple operation; blade coating is ideal for medium-to-high viscosity slurries or those containing particles, with a wide range of film thickness control; slot-die coating provides the highest precision and is suitable for high-end applications such as electronic films.
Standard Test Method for Measuring Optical Haze of Transparent Coated Films Using a Haze Meter
This article introduces the standard method for measuring the optical haze of transparent coated films using a haze meter. First, the instrument must be calibrated according to the standard, and the sample needs to be conditioned in a constant temperature and humidity environment. The measurement involves four steps, including air zeroing, measuring total transmission and scattered light flux, and finally calculating the haze value.
