Technical specification

Automatic film applicator coater

• Automatic laboratory equipment for accurate and reproducible application of coating materials, adhesives and similar products.
• Adjustable start and stop position.
• For use with almost all film applicators.
• Easy to handle.

• other applicators have to be positioned before weight support
• adjust the desired application length
• fix the desired substrate, e.g. test chart, with the start position clamp
• set the desired drawing speed (1-99 mm/s)
• pour the product to be tested in front of the applicator in drawing direction
• starting ZAA 2300 Automatic film applicator coater

Handling

• choose an adequate length of the substrate that enables an uniform movement of the apparatus to be made
• place the substrate on a flat, plane laboratory table (ideally made of glass) and, if necessary, fix it with adhesive tape
• put the chosen rubber roller in the frame
• slip the weights on the chosen engraved roller above the o-rings until the stop position is reached and put it afterwards in the frame above the rubber roller
• place now some coating material on the contact area of both rollers (engraved and rubber roller)
• disperse the coating material by turning the engraved rollers at the weights, by doing so you will reach right at the beginning an uniform width of the print proof
• put the apparatus on the substrate and draw it uniformly over it, without additional pressure by the guiding hand
• for the examination only use uniform parts of the print proof
• dismantle the apparatus after every print proof and clean it carefully with a suitable solvent
