1. Regarding the gloss of PU paint matte series. There are many reasons that affect the gloss of matte varnish, including the spray thickness of the paint, the drying speed of the paint, the uniformity of mixing before spraying, the ventilation of the production site and the relative humidity of the air in the production site all have an impact on the gloss of the paint. .
2. For some paints, because of the different curing agent, the dissolving power of the thinner, the volatilization speed, and the thickness of the coating film, they will all have an impact on the performance and mattness of the final paint film. Therefore, it is necessary to pay attention to the production. Use matching curing agent, thinner, etc.
3. The influence of winter on paint. The viscosity of paint is greatly affected by temperature. As the temperature increases, the viscosity decreases, and when the temperature decreases, the viscosity increases. In winter, the thinner will increase and the viscosity will become low. It is prone to quality problems such as poor fullness, sanding, poor hand feeling, reduced gloss, and poor sand mark covering ability. Therefore, pay attention to the storage temperature of the paint in winter, and the temperature of the paint mixing place should be kept as the same as possible.
