Paint knowledge: formula design of automobile flash paint

Key tips: pay attention to the following points in the formulation design of automobile flash coating: The key is how to make the effect pigment parallel orientation The solid content of construction should be low, so that there is a large shrinkage pressure from wet film to dry film The solid content is low, but the viscosity cannot be too low, otherwise the orientation of the effect pigment is poor Cellulose is used to thicken the solvent based flash paint, and resin with strong thixotropy or water-based cellulose is used as the water-based system The volatilization rate of the solvent should be relatively fast, too slow to make the aluminum powder parallel oriented Pre drying process must be added to water-based system The polarity of the solvent in the finishing coat should not be too strong, otherwise it is easy to make the oriented aluminum powder Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: the formula design of automobile flash paint should pay attention to the following points: the key is how to make the solid content of the effect pigment parallel directional construction low, so that the wet film to the dry film has a large shrinkage pressure and the solid content is low, but the viscosity cannot be too low, otherwise the orientation of the effect pigment is poor In solvent based flash paint, cellulose should be used to thicken In water-based system, resin with strong thixotropy should be used, or the evaporation rate of water-based cellulose solvent should be relatively fast Too slow, it is not easy to make aluminum powder parallel oriented In water-based system, it is necessary to increase the polarity of solvent in the pre baking process finishing coat, otherwise it is easy to make the oriented aluminum powder be bitten again Attention should be paid to the following points in the construction of metallic flash paint: the key of metallic flash paint: parallel directional construction of effect pigment, solid separation, low solvent system, high volatility, no drying and no wetting, large paint output, small air output, thixotropic water-based paint, pre baked line paint home, focusing on coating, diatom mud, paint coating, coating technology, fire-resistant coating news and coating, Decoration knowledge and effect drawing of diatom mud, paint coating, coating process, fireproof coating,
