The following introduces the quality standards of typical colored paints, and the following table shows the technical requirements.
Composition of F06-9 zinc yellow and iron red pure phenolic primer (ZBG 51025-87 instead of HG2-580-74)
The paint is made of pure phenolic resin, dry oil, zinc yellow or iron red, extender pigment, drier, and xylene or turpentine.
characteristic
It has a certain anti-rust ability and good water resistance.
use
Zinc yellow pure phenolic primer is used to coat aluminum alloy surfaces, and iron red pure phenolic primer is used to coat steel surfaces
experiment method
The drying time shall be carried out according to Method A in GB1728-79 "Determination of Drying Time of Paint Film and Putty Film". Paint film thickness is 20μm±3μm
The hardness is carried out according to GB1730-79 (confirmed in 1985) "Determination of Paint Film Hardness". The paint film is measured after drying according to the drying conditions, and the thickness of the paint film is 20μm±3μm
The flexibility is measured according to GB1731-79 "Determination of Flexibility of Paint Films" after the paint film is dried according to the drying conditions, and the thickness of the paint film is 20μm±3μm
The impact strength is carried out according to GB1732-79 "Determination of Impact Resistance of Paint Film". The paint film is measured after drying according to the drying conditions. The thickness of the paint film is 20μm±3μm.
Adhesion is carried out according to GB172079 (confirmed in 1985) "Determination of Paint Film Adhesion". The paint film is measured after drying according to the drying conditions, and the thickness of the paint film is 20μm±3μm.
Salt water resistance is tested according to 3(1) A method in GB173679 (confirmed in 1985) "Determination of Chemical Resistance of Paint Films". The paint film is measured after drying according to the drying conditions. Aluminum plates with zinc yellow primer and thin steel plates with iron red primer are sprayed in 2 coats, each coat is baked at 105°C±8°C for 1 hour, and the film thickness is 45μm±5μm.
The heat resistance is carried out according to GB173579 "Determination of Heat Resistance of Paint Film". The paint film is measured after drying according to the drying conditions, and the thickness of the paint film is 20μm±3μm.
construction reference
① Dilute with xylene and turpentine during construction. It can be sprayed or brushed, and the top coat is usually applied after two coats of primer. Do not brush too thickly (due to the poor hiding power of the zinc yellow pure phenolic primer, it is usually transparent when the first coat is applied. It is slightly transparent when the second coat is applied). The dry paint film thickness should not exceed 20m per coat.
②The matching surface is alkyd enamel, amino baking varnish, pure phenolic enamel.
