This test method provides a systematic means for screening coating materials aligned to this property. The ability of a pipe coating to avoid mechanical damage during handling, shipping, and installation depends on its impact resistance. This test helps in determining when, where, and how the paint or coating failure can occur. The coating then continues to dry until the coating is totally cured. Once it starts to cure, a thin dry film appears on the surface. The first stage is when the coating levels off under gravity. The coating’s drying time involves multiple stages. When developing a process, it is crucial to know the definite time it would take for the coating to dry or cure. This test is done to know the timeline, when a coating is totally dry. This test helps in determining the corrosion degradation of coating systems for steel bridges. This test helps in determining the adhesion of a large variety of coatings. Condensation is produced by exposing the test surface of the sample to a heated, saturated mixture of air and water vapour, while the reverse side of the sample is cooled under an air of room temperature air. This test helps in determining the resistance of organic coatings by controlled condensation. Test Method: IS: 6745-1972 Condensing Humidity Test: This test helps in determining the thickness of paint plating, coatings and galvanization on iron steel. If the profile is too high, there is the danger that the profile peaks will remain uncoated. The adhesion to the coating of the surface can be reduced if the profile is too low. The proper and effective preparation of a surface prior to coating makes sure that the correct roughness or profile is generated. This test helps in determining the hardness of the paint coat. This test helps in determining the resistance of surface coatings (paint, clear coats, metallic plating, etc.) to chipping caused by the impacts of gravel or other flying objects. This test helps in determining the ability of a coat to resist chemical deterioration or staining. This test helps in determining the corrosive performance of decorative copper/nickel/chromium or nickel/chromium coatings on steel, zinc alloys, aluminium alloys, and plastics designed for severe service and testing of anodized aluminium.
This is an important property for paints applied in bathrooms, kitchens and laundries. This test helps in determining the degree to which a paint resists reaction with alkaline materials such as lime, cement, plaster, soap, etc. Abrasion resistance can be intensified by the inclusion of surface changing additives.Īdhesion testing in the paint and coating industries is necessary to ensure the paint or coating will adhere properly to the surface to which they are applied This test helps in determining the ability of a coating to resist degradation due to mechanical wear and tear by hard and rough objects.
