Overview
The LENETA coating applicator TAT-684 is an instrument for preparing wet-film with a film width of 4 inches, spacing of 6-8, wet film weight of 3-4, and dispersion speed of 535-400.
Features
The model number is TAT-684, and the film width is 4 inches.
2. The interval range is 6-8.
3. Wet film weight range is 3-4.
The dispersion speed range is 535-400.
Principle
The coating applicator through a preset film width and spacing, scraping coating or dispersion on the substrate to form a uniform wet-film having a specific film thickness (wet-film weight), which dispersion speed parameter for controlling the Spreader process.
Applications
Paint preparation, inks testing, dispersion studies, wet-film sample preparation
Steps
1. Place the paint or dispersion to be tested on one end of the substrate.
Scrape the coating applicator smoothly across the substrate at a set angle and speed, such as in the 535-400 dispersion speed range.
3. Form a uniform wet-film on the substrate.
4. Follow-up processing or measurement of wet-film according to test requirements.
Notice
• Make sure the coating applicator is clean and free of residue before use.
• Maintain a steady and uniform speed during operation to obtain a consistent wet film thickness.
• According to different test materials and requirements, choose the appropriate interval and dispersion speed parameters.
• Clean the coating applicator in time after use to avoid coating curing affecting the next use.
