Paint knowledge | how much is the price of epoxy primer? Introduction to the function of epoxy primer

Core tip: solventless epoxy primer is also called epoxy high strength coating Modified epoxy resin was used as the main film-forming material, and active dilution toughened polyurethane was used as curing agent to realize solventless Solventless epoxy primer gives the coating good adhesion, excellent chemical stability and mechanical properties The addition of flake fillers in solventless epoxy primer can not only improve the mechanical properties of the coating, but also play a good role in coating shielding and corrosion protection The viscosity of the curing agent for solventless epoxy coating is low, and the cured coating has good corrosion resistance, hardness, toughness and compactness Function of epoxy primer 1 Sealing: some walls are alkali Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings: solventless epoxy primer is also called epoxy high strength coating Modified epoxy resin was used as the main film-forming material, and active dilution toughened polyurethane was used as curing agent to realize solventless Solventless epoxy primer gives the coating good adhesion, excellent chemical stability and mechanical properties The addition of flake fillers in solventless epoxy primer can not only improve the mechanical properties of the coating, but also play a good role in coating shielding and corrosion protection The viscosity of the curing agent for solventless epoxy coating is low, and the cured coating has good corrosion resistance, hardness, toughness and compactness The function of epoxy primer 1 Sealing: some walls are strong in alkalinity After being soaked by moisture and water, alkali flowers are produced The scientific name is "Pan alkali" This situation causes crater like protrusion on on the surface of the paint film In serious cases, an alkali frost is formed on the surface of the paint film, which eventually damages the paint film Latex primer can play a sealing role and alleviate this situation However, if the walls of your house are dry and the floors are high, it may not be necessary and there will be no problem, but it is recommended that you use, insurance 2 adhesion: primer has high emulsion content and strong adhesion It can improve the adhesion between emulsion paint film and wall 3 Filling: if your wall is not strong alkaline and relatively flat, you can use no primer, which is better At present, the price of epoxy primer is widely used in the market Brands such as libon and Dulux are widely used in China The imported ones are mowell and Dutch kid from the United States, Dufang from Germany, etc the rest are relatively uneven miscellaneous brands or small brands Due to the problems of exchange rate and conversion of imported goods, Xiaobian mainly introduces some commonly used domestic products Libang: a well-known brand in China The price of the two-component epoxy finish for flooring is about 540 yuan, 20kg, i.e one barrel It provides a variety of colors, with a shelf life of 12 months Europa: it is also a brand that often appears in people's vision The price is about 340 yuan and 16KG It provides the choice of milk yellow, dark yellow, emerald green, sky blue, color blue, scarlet, iron red, light grey, black, dark grey, fruit green, medium green and other colors The product is used by ab set Shanggong: established in 1942, it is an old brand The price is about 35 yuan per kg, and a flagship store has been opened in tmall Those who are not convenient for local purchase can also go to Tianmao for purchase Epoxy primer construction products are mainly used in decoration and various construction projects, not only for all kinds of pipes, but also for different steel equipment As a kind of protective primer, it can absolutely make its relevant facilities to achieve more oil, water and corrosion resistance Let's take a look at the key points of the construction of epoxy primer 1、 Before preparing the epoxy primer, remember to mix the curing agent added to it evenly 2、 In each preparation of epoxy primer, the use time of relevant paint, construction capacity of the project, daily demand and other factors should be taken into account 3、 Paint in strict accordance with the product manual of epoxy primer, when to use and when to mix And ensure that the prepared paint is in the specified time range and used up Once the prepared paint exceeds the specified time, do not use it again This not only affects the engineering quality, but also leads to poor paint performance Epoxy primer ratio The proportion of epoxy primer is simply a mixture of epoxy resin and curing agent plus some other chemical components Its proportion has very strict requirements Some comrades asked me if the more curing agent it is, the longer it will be used firmly Here's a small braid telling you, don't do this If there are too many curing agents, the flexibility of the paint film will be reduced It's very Easy to disconnect If the curing agent is too little, it is not easy to dry Even if it is dry, the corrosion resistance of the paint film will be reduced a lot The correct ratio is that the weight ratio of epoxy resin and curing agent is 10:1 or 6:1, and the amount of diluent is generally 15-35% of the paint Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating
