Applicators with 4 gaps
Applicators with 4 gaps are BYK-Gardner film applicators used to create film applications of coatings, paints, inks, varnishes, adhesives, and other liquid materials with four gap clearance options in one tool. These applicators help users produce uniform, controlled, and repeatable drawdown films on test charts, panels, or plane substrates.
In paint application testing, film thickness variation strongly affects the evaluation of color, gloss, opacity, hiding power, leveling, flow, drying behavior, and appearance. Applicators with 4 gaps provide greater flexibility because users can choose multiple application thicknesses without changing applicators. This makes R&D, formulation comparison, batch comparison, and quality control workflows more efficient.
Applicators with 4 gaps are available in several designs such as bar-shaped, 4-sided applicator, and frame-style applicator. Bar-shaped or 4-sided applicators are suitable for higher viscosity materials, while frame-style applicators are ideal for low viscosity coatings. These products are made from corrosion-resistant stainless steel, easy to clean, and support the production of uniform films according to ASTM D823 practices.
