Applicators, drawdown bars and frames are tools used for the controlled preparation of defined film drawdowns from paints, varnishes, coating materials, adhesives and similar products. The range includes profile rods, wire-wound film applicator rods, universal applicators and four-sided film applicators.
The selected applicator determines factors including film width, application geometry and nominal wet-film thickness. In automatic applications, an automatic film applicator additionally provides controlled movement at a consistent drawdown speed.
The appropriate combination of applicator, substrate, working surface and drawdown movement provides the basis for comparable test films in laboratories, quality assurance and research and development.
