Gray railway bridge two-component epoxy zinc rich antirust primer epoxy zinc rich prime

  Epoxy resin has the following characteristics and excellent corrosion resistance
Epoxy resin curing coating, containing stable benzene ring, ether bond, etc
, with compact structure, acid, alkali, organic solvent and water resistance
The adhesion of paint film to metal and small structural pores make it difficult for various corrosive media to penetrate the metal surface, so it has corrosion resistance

Good mechanical properties
Due to the alternating arrangement of rigid benzene core and flexible hydrocarbon bond in the epoxy resin cured coating structure, the coating is hard and flexible
In addition, during the curing process, no small molecular by-products are generated, no gas is generated, the volume shrinkage is small, and the coefficient of thermal expansion is 60 & times; 104 / ℃, so that the coating will not crack due to temperature and stress
The paint film has good flexibility, which is 7 times larger than phenolic aldehyde resin

High stability
Epoxy resin itself has good heat shrinkability
It will not cure without curing agent and will not change under heat
Therefore, epoxy resin coating has high stability and will not deteriorate after 1-2 years
Application: it is applicable to the surface of steel structure equipment in shipbuilding, offshore steel structure, bridge, iron tower, petroleum, smelting, chemical and other industries as , When the antirust primer of the base course is used as the maintenance primer after shot blasting or sand blasting of steel plate, the maintenance period is about nine months
It can also be applied to the anti-corrosion of the surface of galvanized sheet

  Color gray
  Proportioning component: two component a (paint) proportioning: 25 component B (curing agent) proportioning: 2
5
Coating methods: brush coating, roll coating, spraying and airless spraying
  Painting interval 1-7 days
The anti-corrosion mechanism of epoxy zinc rich primer is mainly the cathodic protection of steel surface
The electrochemical activity of metal zinc is more active than that of iron
In a corrosive environment, the steel matrix is protected by corrosion sacrifice
Even if the coating surface is damaged or scratched, it will repair itself
Therefore, in order to make the film conductive and play the role of sacrificial anode, it is required that the film contains a large number of particles, which are in contact with each other and keep in contact with the steel matrix
It contains a large amount of primer, which contacts each other in its paint film and contacts with the steel plate to conduct electricity, so that the steel plate is cathodic protected
