Chongqing Supply harmony brand XHDAC205 type Epoxy Mastic micaceous iron heavy duty coatings

1 Introduction This is a peaceful phosphide (Chengdu) headquarters under the professional company, to develop and produce high-tech products on the basis of the introduction of technology. It is based on the traditional epoxy micaceous iron rust on the use of the modified polyamide resin, by adding scaly micaceous iron oxide, anti-corrosion additives, solvents, additives, prepared by the advanced technology of two-component thick slurry-type heavy-duty coatings. 2 Scope For high performance requirements of steel corrosion rust primer, an intermediate layer paint, such as ships, containers, bridges, gas tank (tank), port machinery, steel, etc., can also be used as a zinc-rich primer The additional coating. 3 Main features excellent mechanical properties 3.1. A modified polyamide curing agent, giving more excellent coating adhesion and flexibility of the metal and non-metal has a very strong binding force, the film in a long time to maintain the excellent impact resistance and flexibility . It has good adhesion and sealing performance on zinc-rich primer and steel with zinc layer, and, after the film has good interlayer adhesion. 3.2 good corrosion resistance. Not only to retain the traditional epoxy micaceous iron rust primer good barrier properties, heat resistance, adhesion, and corrosion resistance better. Water vapor and oxygen permeability of the film is low, with excellent water resistance. Industrial and chemical atmosphere has good weather resistance. 3.3 Construction of convenience, room temperature curing. Construction cost less, a film thickness, room temperature curing film. 3.4 improve the coating thickness. Use as an intermediate layer of high performance protective lacquer coating, can increase the thickness of the film to enhance corrosion, rust ability, extend the useful life, they can enhance the decorative surface to improve the surface of bright paint, smooth, fullness . 4 Technical parameters Item Technical parameters testing standards in the container after the state mixing, no lumps, performance was mixed uniformly mixed homogeneous state construction of Brush Roll pot, h ≥ 3 Viscosity (Tu -4 cups, 23 ℃), s ≥ 70 GB / T 1723-1993 fineness, μm ≤ 50 GB / T 1724-1979 solids content,% ≥ 65 GB / T 1725-2007 Surface Drying time (23 ℃), h ≤ 3 GB / T 1728-1989 The actual drying time (23 ℃), h ≤ 24 GB / T 1728-1989 Film appearance gray, smooth adhesion (grid spacing 1mm), grade ≤ 1 GB / T 9286-1998 bending resistance, mm ≤ 2 GB / T 6742-2007 Impact resistance, cm ≥ 50 GB / T 1732-1993 resistance to neutral salt spray 120ha no blistering, no loss, no rust GB / T 1771-1991 salt water (5% NaCl, 23 ℃ , 7d) no blistering, no loss, no rust GB / T 1763-1979 Alkali (5% NaOH, 23 ℃, 7d) no blistering, no loss, no rust GB / T 1763-1979 oil resistance (dipped in kerosene, 23 ℃, 7d) no blistering, no loss, no rust HG / T 3343-1985 a. test time can be agreed upon in accordance with the requirements of mixed. 5 Construction 5.1 Preparation method: first to the bottom of the barrel thoroughly mix the paint without sediment and press coating curing agent ratio and 8: 1 (by weight) was added XHDAC205 based paints special hardener, stir appropriate aging time (about 20min) after use. 5.2 Surface treatment requirements: When the coated metal surface, sandblasting, shot blasting Sa2 to the country level associate, to keep the surface dry and paint in 4 hours; when concrete coating shall be dried before painting to water parts ≤8%, and the surface is clean. 5.3 Use of: paint formulated recommendations about used within three hours (20 ℃) ??time. Never will not run out of paint into the original paint in. 5.4 Coating Thickness: airless spray, dry film thickness of about 100μm or so. 5.5 Theory of consumption: If you do not consider the environmental impact of the coating when the actual construction, coating method, coating technology, surface condition and structure, shape, surface area size, the general consumption of about 0.35kg / m. 5.6 Painting by recommendations: To make the coating formation, preferably high-pressure airless spray, in the absence of high-pressure airless spray conditions, the only choice of air spray, manual spray coating methods as a third choice. 5.7 thinner amount: generally do not add thinner if the paint is too thick indeed, may be appropriate to add XHDAC205 dedicated thinner, in an amount of 3 to 10%. 5.8 Cleaning of tools: Available XHDAC205 type thinner for cleaning. 5.9 After the completion of final paint coating shall be natural cure for 7 days can be put into use. If the environment is below 10 ℃, it should be extended. 5.10 Environmental conditions: suitable environment temperature is preferably 10 ~ 35 ℃, relative humidity not more than 85%, the substrate surface temperature should be higher than the dew point temperature 3 ℃. 5.11 Other painting note as "painting and maintenance considerations." 6 Packaging and storage 6.1 Packaging: iron drum sealed packaging, Part A barrel weighing 20kg, barrel curing agent NW 15kg, barrel diluent net 15kg. 6.2 Storage and transport: is flammable, keep away from fire and stored in a cool dry ventilated place. Avoid collisions. 6.3 is valid for one year, over the period, after re-inspection can still be used. 7 7.1 Health and safety construction site should provide adequate ventilation, avoid absorbing solvent vapors and paint mist, skin and facial features can not contact with the product, to prevent poisoning, contact applications such as plenty of water, and then a suitable detergent or soap and clean water and medical treatment, as appropriate. 7.2 construction site should take reliable safety precautions, prohibit all sparks, open flame, non-smoking. 7.3 of used packaging materials are dangerous paint waste, can not mix with the general waste.
