Abrasion
RAJ - Abrasion Tester
Taber Abrasion is an standard used to determine wear and tear of the coatings. It is used to determine the abrasion resistance of organic coatings produced on a plane, rigid surface. The sample is applied to a plane rigid panel. Sample panel shall be a disk of 4 inch (100 mm) in diameter or square (100 x 100 mm) with rounded corners. A hole of 6.3 mm should be located at the centre of each panel. The weighted specimen is mounted on a turntable disc and place the abrasive wheel on the test film. The result varies according to the load applied on the wheel. Taber Abrasion is used for quality & process control, research & development and material evaluation. It is widely used in coating, textile, leather, rubber, plastic, wood, glass, paper, lamination, ceramics.
Adhesion / Wet Film Gauge
RAJ - Cross Hatch Cutter
Cross Hatch Cutter is used to conduct the adhesion test of coatings after full curing of paint film. It provides an instant assessment of the quality of the bond between the coatings and the substrate.

Coating Thickness Gauge
RAJ - Wheel Type Wet Film Thickness Gauge
The Wheel Type Wet Film Thickness (WFT) Gauge from Raj Scientific Company is an essential tool for accurately measuring the thickness of wet coatings. It features a unique design with three circles, where the central circle of smaller diameter is accompanied by two eccentrically placed outer circles. These outer wheels are notched and provide a firm grip, ensuring stability and precision during use. The gauge is engineered with a precision roller bearing that facilitates smooth traversal over the wet surface, providing accurate readings. The scale on the outer circles, expressed in microns, corresponds with the measurement point where the central circle contacts the coating. This tool aids in achieving consistent coating application by allowing operators to verify the uniformity of the coating layer. It is particularly beneficial for professionals in the coating and painting industries, ensuring that the specifications and standards of wet film thickness are consistently met.Coating Thickness Gauge - Grinding & Dispersing
RAJ - Automatic Digital Pigment Muller for Paint and Coating Industry
The Automatic Digital Pigment Muller is a vital laboratory instrument designed for the evaluation of pigment resin or linseed oil paste. It is primarily used for assessing shade, mass tone, reduction tone, tint tone, opacity, and pigment strength, ensuring consistency in quality control across various industries. This equipment is extensively utilized in paint, coating, ink, cosmetics, plastics, electronics, and chemical industries. It operates under standardized conditions as per ASTM D 387, ASTM D 332, ASTM D 2745, and ISO 787-13/16/24.
