Why choose the 433 Wet Film Comb for paint testing? People pay more and more attention to the environmental performance of coatings, and many coating brands carry test certificates to show how good their products are. But many people don't know what the routine tests for coatings are. Here is a summary.
Basic properties: coating thickness, density, viscosity, fineness of grind, moisture content, solids content, acid value.
How the Erichsen 433 Wet Film Comb from Sinotime measures paint more accurately and conveniently:
433 Wet Film Comb
Portable and simple to use, even by non-technical staff; well designed and sturdy, with readings that are clear at a glance.
Measures on any surface. Because it works mechanically, there are no restrictions on the substrate: it can measure coating thickness on glass, wood, plastics and metal.
Compared with other types of thickness gauge, mechanical gauges have a price advantage.
Physical properties: adhesion, pencil hardness, abrasion resistance, impact resistance, bend resistance, cupping, scrub resistance.
Optical properties: colour, colour difference, gloss, hiding power.
Electrical properties: surface resistance, dielectric strength.
Chemical resistance: resistance to water, alcohol, solvents, acids and alkalis, oil, cleaning agents and staining.
Thermal properties: heat resistance, damp heat, low temperature, thermal shock, constant temperature and humidity, hot–cold–humid cycling.
Biological properties: mould resistance.
Ageing: accelerated UV ageing, xenon arc ageing, salt spray, water spray, hot air ageing.
Assessment after ageing: colour difference, cracking, blistering, erosion, chalking, flaking.
Safety and environment: VOC, formaldehyde, benzene, toluene, xylene, free TDI, PAHs, heavy metals to EN 71-3, ASTM F963, RoHS, fire safety.
That covers the main ones. Different types of coating focus on different tests: interior wall paints focus on safety and environmental properties, anti-corrosion coatings on acid and alkali resistance, and so on.
