Assisting industrial coatings water-based transformation and upgrading coating standards committee network to declare new standards for products

China Coatings Network
News: With the increasingly stringent environmental regulations, especially on February 1, 2015, the national VOC content of more than 420 g / liter (including) of
coatings
after the imposition of a 4% consumption tax policy, the traditional solvent-based industry
coating enterprises
to water, powder and other environmental protection direction of the transformation and upgrading process has been fast horse whipping.
Among the many
water-based coatings
systems, water-based polyurethane coatings, water-based epoxy coatings and water-based acrylic coatings are the areas of most concern, and since June 1, 2015, HG/T4761-2 has been developed by the National Technical Committee for Standardization of Coatings and Pigments (SAC/TC5). 014 "Water-based polyurethane coatings", HG/T4759-2014 "water-based epoxy resin
anti-corrosion coatings
", HG/T4758-2014 "water-based acrylic coatings" and other 3 water-based
industrial coatings
product standards will be formally implemented. The implementation of these standards will be an important milestone in the development of water-based industrial coatings in China.
At present, China's water-based polyurethane coating market is in the initial stage, has not really formed a scale, but with the general promotion of environmental awareness of the whole society, especially the environmental protection regulations of various countries on the voC content requirements in the paint increasingly strict, the technology is becoming more mature and the cost of raw materials gradually reduced, water-based polyurethane coatings will usher in a vigorous development opportunities. HG/T4761-2014 "water-based polyurethane coating" new standard is applicable to water as a dispersion medium, polyurethane resin as the main film, add
pigment
(varnish) Without addition) and additives applied to metal and cement mortar, concrete and other inorganic non-metallic substrate surfaces to play a decorative and protective role in the normal temperature self-drying single, double-group and single-part high-temperature baking type water-based polyurethane coating. The standard divides water-based polyurethane coatings into metal surface coatings and inormeric non-metallic surface coatings, and puts forward the relevant technical index requirements.
, epoxy coatings account for a considerable proportion of corrosion-resistant coatings used in steel structures. The traditional solvent-based epoxy coating has produced a large number of volatile organic volatiles in the production and construction process, so the hydration development of epoxy resin has been put on the agenda. Although water-based epoxy resins have been studied for more than 25 years and water-based epoxy coatings have been used for more than 10 years, the overall application of water-based epoxy resins and water-based epoxy coatings have not yet formed large-scale production and application. At present, the quality and protective effect of water-based epoxy anti-corrosion coatings on the market are not satisfactory, often coating accidents. Therefore, an industry standard is needed to regulate the production, construction and application of this type of coating. HG/T4759-2014 "water-based epoxy anti-corrosion coating" new standards applicable to metal substrate water-based epoxy anti-corrosion coating, respectively, the primer, intermediate paint, paint put forward the relevant technical indicators.
-based acrylic coatings are used not only in industrial or civil applications as protection against metals such as steel, but also, in many cases, as protection against cement or wood. This water-based coating is highly competitive in terms of environmental protection, performance and price, including climate aging resistance and reduced volatile organic compound content. In foreign countries, the product has been a considerable degree of popularity, in the domestic application of its more and more extensive. At present, there are a variety of water-based acrylic protective coating products on the market, because there is no uniform standards and norms, its product quality, environmental protection requirements and construction effects are uneven, the urgent need for relevant product standards to regulate the market. HG/T4758-2014 "Water-based acrylic coating" is suitable for acrylic resin as the main
film substance
of the water-based single or two-cell coating, products are mainly used for metal surface decoration and protection. The standard divides the water-based acrylic coating into I. type baking cross-curing type coating, II.type room temperature self-drying type single-part coating and III.type normal temperature cross-curing type double-part coating, and puts forward the relevant technical index requirements respectively.
In order to keep the industry relevant to the background of the development of the above new standards, the relevant industry development status, standard-setting process, standard-setting principles, the scope of application of standards and product classification, especially the standards in the indicators of the setting and related test methods and standard-setting process of verification test data and other related content, to help the industrial coatings industry hydration transformation and upgrading, the National Coatings and Pigment Standardization Technical Committee and the National Paint Quality Supervision and Inspection Center will be held in Changzhou on May 15, 2015 the first training course on paint standards. At that time, the main drafters of the relevant standards will want the industry to explain the relevant content of the standards in detail.
The same period of this training will also explain the national standard GB/T30790.1 to 8 "protection of the protective coating system on steel structure corrosion protection Part 1 - Part 8" and the newly issued mandatory national standard GB30981-2014 "building steel structure corrosion protection coatings in the limit of harmful substances" related content.
The National Technical Committee for Standardization of Coatings and Pigments understands that many enterprises are very concerned about these new standards, but are limited by time, manpower, financial resources and other aspects, can not come to the scene to participate in the training. To this end, the coating standard committee and the National Paint Quality Supervision and Inspection Center will be the first time in cooperation with the Chinese Chemical Society coating professional committee, through its "paint industry" WeChat platform, the introduction of free registration can participate in online training activities.
the schedule of training activities isAs long as you are in the paint industry, fill out the registration form truthfully, you can participate in free training on any broadband connected computer or notebook. If equipped with a camera and microphone, you can also interact online.
