1. Supporting products: Thinner for epoxy paint, curing agent for epoxy topcoat, supporting epoxy intermediate paint, epoxy zinc- rich primer or epoxy primer
2. Mixing ratio, weight ratio
Base: hardener: thinner = 4: 1: 0~1.2
Ratio and viscosity of the paint can be properly adjusted according to the actual conditions.
3. Application method: Spraying (main) or brushing
4. Application instructions: Make sure there is no water, dust or oil on the steel surface and conduct sand blasting (shot blasting) for the steel surface till the Sa2.5 level and a surface roughness of 30μm to 70μm. The substrate should have a temperature more than 3℃ higher than the dew point and a relative humidity lower than 80%. Do not apply the paint when the substrate temperature is below 5℃. If the substrate temperature is below 15℃, curing will be slow. It is suggested to spray or brush two layers of antirust paint and one layer of maintenance paint with an interval of one to a period before zinc salt forms on the paint film and make the dry paint film thickness of each layer 20μm to 25μm, the theoretical coverage of each square meters on each layer 0.13 kg to 0.17kg and the maximum application duration (at 25℃) 8h. Thoroughly mix the two parts according to the mixing ratio and make the paint cure for about 30 minutes before application. Apply thinner if necessary.
