一. The construction of pre coated primer:
1. before spraying, the substrate must be treated, requiring no rust, no oil stain, and keep clean and dry.
2. the product is a two-component system. First, mix the paint mixture, add the curing agent to the ratio, and mix it for 30 minutes.
3. use special diluent to adjust the viscosity of the construction; according to the amount of the paint, how much should it match, the paint should be used in 8 hours.
4. it is recommended that the coating should be sprayed with a viscosity of 15-18 seconds (-4#) and a maximum thickness of 25 m.
