Everyone knows that there are many types of paints, and each kind of paint is suitable for spraying different products, so it is necessary to choose the paint according to the actual use. When we choose a paint to spray our products, how should we choose different caliber paint spray guns?
Paint mainly depends on its viscosity. For general paint, the commonly used caliber is 1.0MM or 1.3MM. Common 1.0MM is topcoat spray, 1.3 is primer spray. The above two calibers refer to general UV paint and ordinary paint.
But when we spray polyurethane paint, we need to pay attention to the automatic spray gun with a slightly larger caliber, such as the caliber above 1.5MM. The main reason is that its viscosity will be much higher than the viscosity of our ordinary paint, and large-caliber spray guns will not be particularly easy to block.
In addition, when selecting the caliber, we need to use a viscosity cup to measure the viscosity of the paint. Such viscosity data will be more accurate and can help us choose a suitable paint spray gun.
