The Conical Mandrel Bend Tester offers a practical means to evaluate the quality of the paint by bending a metal substrate on its cone, duly coated with paint to a specific angle . This enables us to determine the ability of a coating to resist cracking or detachment from its substrate. Additionally, flexibility properties and the adhesion property of coatings can also be assessed for flexible substrates. This instrument is most befitting to test the resistance of paint, varnish, and coatings.
A coating thickness gauge (Also Known as a coat meter) is used to measure dry film thickness of paint. Dry film thickness measurement is the most captious step in the coatings industry because of its impact on the coating process, quality and expense. The measurement can be used to evaluate a coating’s expected life, the product’s appearance and performance, and ensure compliance with the International Standards. Dry film thickness can be measured through two different ways I.e, destructive density measurement, where the coating is cut-through till the product surface using a cutter; and non-destructive coating density measurement, using techniques which do not damage the coating such as magnetic induction thickness measurement methods.
A scratch hardness tester is used to determine the hardness and strength of a coating to scratches and abrasion. A round point bends the material under a fixed force spring and the hardness is displayed on the dial in the measurement unit of Shore Hardness.
An instrument used to determine a fluid's thickness and flow resistance (AKA viscosity) is known as viscosity cup. The process begins with introduction of sample of the fluid into a container with a hole in its bottom and recording the time taken for the container to empty when draining the fluid through the opening. The speed of the fluid is inversely proportionate to its viscosity .
A muffle furnace an oven-type equipment that is named so, because it isolates the subject material from fuel and all of the products of combustion, including gases and flying ash. It is a front-loading box-type electric oven used for creating enamel coatings. The insulating material used in the muffle furnace body effectively acts as a muffle, preventing heat from escaping.
Gloss meter is used to measure the specular reflectance (aka gloss) of a painted surface by directing a constant intensity light beam, at a fixed angle, on the surface and then observing the amount of reflected light from the equal but opposite angle.
For better finished products, weight per litre cup is used to get accurate measurements. It gives clear conversion of litres into weight and vice versa.
