RDS 3 #1/2 "Steel Wire Drawdown Rod film thickness 6.9μm Wire diameter 0.08mm

What's the difference between this and 3/8?

The diameter of the stainless steel rod in hand is different, and the film thickness and film effect are the same, which can be completely replaced.

Do you support customization? Such as wet film thickness and length?

Spreader rod length and main rod diameter support customization, but wet film thickness RDS has provided dozens of specifications covering more than 200 microns, and in principle does not accept customization.

Does the Applicator rod meet the specifications of ASTMD4147?

Model 3 #1/2 "Applicator rod

Can this coating rod be prepative of multi-layer ultra-thin film?

The wire rod can be prepared for 1.5 micron ultra-thin film. Everyone must know it, but another advantage of it is multi-layer film, which is much better than I-shaped film applicator. But multi-layer film tests the flatness of the previous layers of film drying. Generally, the film thickness (such as less than 10 microns/layer) is too thin to control. The wire rod with Film Applicator is a very good solution, eliminating the problem of uneven pressure and speed of hand scraping.
