Coating classification: solvent based architectural coating and its advantages

It is suggested that solvent based architectural coating is a kind of architectural coating with organic solvent as dispersion medium Although solvent based architectural coatings have the problems of environmental pollution, energy waste and high cost, they still have a certain range of application, such as acrylate architectural coatings, silicone acrylate architectural coatings, polyurethane coatings and fluororesin architectural coatings This shows that solvent based architectural coatings have their own obvious advantages in addition to the above defects Compared with water-based coatings, the advantages of solvent based coatings are as follows: The quality of the coating film, because the gloss and fullness are the embodiment of decorative coating film 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 Home of coatings: solvent based architectural coatings are based on organic solvents as the dispersion medium Although solvent based architectural coatings have the problems of environmental pollution, energy waste and high cost, they still have a certain range of application, such as acrylate architectural coatings, silicone acrylate architectural coatings, polyurethane coatings and fluororesin architectural coatings This shows that solvent based architectural coatings have their own obvious advantages in addition to the above defects Compared with water-based coatings, the advantages of solvent-based coatings are as follows: the quality of coating film, because gloss and fullness are two important indicators to reflect the quality of decorative coating film, in the occasion of high decorative requirements, the fullness of water-based coatings usually can not meet the requirements of people, high gloss coatings use solvent-based coatings to achieve For the adaptability of various construction environments, controlling the volatilization rate of solvent is an important parameter to obtain high-quality coating during the construction of most solvent based coatings This is easy for solvent based coatings, as long as the proportion of mixed solvent can be adjusted But for the water-based coating, it is impossible to adjust its evaporation rate, and it is impossible to adjust its evaporation rate, and the ambient temperature and humidity also have a great impact on the water evaporation rate The higher the humidity is, the slower the drying is Under 100% relative humidity, the water-based coating is impossible to dry Therefore, in order to obtain high-performance water-based latex coating, it is necessary to control the temperature and humidity of the construction environment However, in some harsh environments, such as the construction on the outer wall and bridge, it is impossible to create a temperature and humidity controllable condition manually The volume proportion can be adjusted according to the change of the location and climate to achieve the control of the volatilization rate, and the high-quality coating film has been obtained Solvent based coatings have a wide selection of resins For different specific purposes, when choosing different types of coatings, it is mainly to choose the resin system used In solvent based coatings, almost all kinds of resins can be dissolved in solvents, so there is a wide choice Different resins have different unique properties, such as polyurethane resin with excellent weather resistance and chemical resistance, high gloss, wear resistance, etc silicone resin has excellent heat resistance, which can be used as the base material of heat-resistant and weather resistant coatings These resin brands are also mainly used in the solvent coating at present Cleaning problem, no matter water-based coating or solvent based coating, production and construction equipment shall be cleaned during production and construction For solvent based coatings, although the waste solvent after cleaning can be reused through collection, the recovery cost is high, the pollution is large, and the operation is harmful to the recognized health For water-based coatings, some of the cleaning wastewater in the production line may be recycled and reused Even if it is not recycled, it can meet the requirements of environmental protection after being purified and discharged by the wastewater treatment device The construction tools of solvent based coating must be cleaned with solvent, which is harmful to human body and environment The construction tools of water-based coating can only be cleaned with clear water, which is harmless to human body and environment Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
