usage method:
(1) Base Material Treatment: If the surface of the white panel is too rough, it needs to be dry-grinded to remove dust. Then, effectively seal the white panel by applying our company's sealing primer "Dibao" once. After drying, sanding can effectively remove wood fibers and thorns, increase the hardness of the base material, enhance the adhesion between the base material and the primer, and reduce the amount of primer used.

(3) Paint composition: PE series unsaturated polyester primer is composed of multiple components: primer, promoter (blue water), initiator (white water), diluent, which are sold in separate packages. When used, it should be correctly mixed and filtered according to the weight ratio for spraying.
(4) Paint mixing method: divide the used primer into two equal parts, one part is mixed with initiator (white water) and appropriate diluent to make A; the other part is mixed with promoter (blue water) and appropriate diluent to make B; keep them ready, when spraying, take equal weight of A and B, mix and filter them, and spray immediately.
(5) Construction Method: Mix A and B in equal amounts each time, stirring until just one spray can is full. After filtering, apply the mixture to the white base that has been sealed with "Dibao." Generally, two "crosses" are sufficient. When the ratio is correct, the surface should dry within about 40 minutes (25°C). If significant errors occur, check repeatedly and adjust the ratio to achieve normal results.
matters need attention:
(1) Shellac paint cannot be used as the closed primer of PE series, otherwise it will affect the adhesion and heat resistance of the primer.
(2) The amount of blue and white water and diluent should be adjusted according to the requirements of temperature, humidity and season. When the ambient temperature is low and the construction requirements are fast, the amount of blue and white water can be increased appropriately; otherwise, it should be reduced. When the humidity is too high and the temperature changes little, the amount of blue water can be increased significantly.
(3) The amount of blue and white water added is also limited. If too little is added, the crosslinking of the paint film is insufficient, the hardening is slow, the grinding is difficult, and the comprehensive performance is poor. If too much is added, the crosslinking of the paint film is accelerated, the service life of the mixed paint is short, the spray gun is easy to block, and the film is easy to crack after formation.
(4) The amount of diluent added is adjusted according to the construction conditions (shape of white body, temperature and humidity, spray gun specification, vertical or flat spraying), so as to achieve the ideal coating viscosity, coating thickness, leveling without sagging and other purposes. The amount of diluent added should be less rather than more, otherwise it will lead to drying and grinding difficulties.
(5) During continuous construction, the spray gun, spray pot and pipeline should be cleaned frequently with diluent to wash off the old paint, and then the paint should be adjusted for use. After construction, the whole set of equipment must be thoroughly cleaned to ensure that the equipment can be used normally for a long time.
(6) The company asks users to pay close attention to production safety. When using PE series paint, blue and white water should not be directly mixed, otherwise it will cause strong explosion and fire. It must (!) be mixed into the paint separately according to the regulations and thoroughly mixed before mixing together.
(7) The mixed paint oil (25°C) should be used up within 15 minutes to avoid gel waste or blockage of equipment.
packaging and storage:
20L iron can packaging, store in a cool, dry and ventilated place. The shelf life is four months from the date of production.
