matters needing attention
1. Before use, mix the paint and curing agent according to the required proportion, mix as much as you use, and stir evenly. After 10-15 minutes, it is better to use it after filtering with 200 mesh screen, and use it up within 6 hours
2. The construction process shall be kept dry and clean. It is strictly prohibited to contact with water, acid, alcohol, alkali, etc. after the paint is prepared, the curing agent packaging barrel must be tightly covered to avoid gelling. During construction and drying, the relative humidity shall not be greater than 85%.
Matching paint
(primer) various colors of polyurethane antirust primer iron red high antirust primer
(intermediate coating) various colors of polyurethane intermediate coating paint gray intermediate coating paint
surface treatment
The painted surface shall be firm and clean, free of oil, dust and other dirt, and free of acid, alkali or moisture condensation. The polyurethane finish coat that has been cured for a long time can be coated only after it is roughened with sandpaper.
