An absolute must-have for professional laboratory testing, product development, and quality control. This custom-assembled RK K Hand Coater Set offers a simple, highly effective, and world-class solution for applying perfectly uniform and repeatable surface coatings across a wide variety of substrates.
This complete system includes three (3) genuine long stainless steel wire-wound rods and one (1) genuine RK large impression bed. It is specifically designed to eliminate operator variability and allow for the simultaneous, side-by-side application of multiple coatings in a single pass—making it the ultimate tool for comparative ink and paint testing.
Accurate & Repeatable Thickness: Meter bars ensure mathematically precise wet film thickness ranging from 4 to 12 microns, delivering consistent drawdown results every single time.
Side-by-Side Comparison: The large testing area enables you to apply two or more coatings simultaneously to check for color density, opacity, drying times, or formulation differences in a single operation.
Universal Substrate Testing: Flawlessly applies paints, printing inks, lacquers, varnishes, resins, and adhesives onto paper, cardboard, plastic films, polymer foils, metal sheets, glass, and wood.
Professional Industrial Quality: Precision-engineered in the UK from high-grade stainless steel for superior corrosion resistance and effortless cleaning with standard solvents.
This complete 4-piece professional kit includes exactly:
1x RK Long Bar #0 (White | KHC.11.0): Deposits a 4-Micron wet film thickness.
1x RK Long Bar #1 (Yellow | KHC.11.1): Deposits a 6-Micron wet film thickness.
1x RK Long Bar #2 (Red | KHC.11.2): Deposits a 12-Micron wet film thickness.
1x RK Large Impression Bed (KHC.21): Features a synthetic rubber surface with a total size of 24 x 34 cm (Coating/Drawdown area of 22 x 34 cm) and a heavy-duty stainless steel clip to hold substrates firmly in place.
