What is the application method for automotive epoxy primer?
1 Answers
Perform surface treatment before painting, including operations such as sandblasting and degreasing on steel surfaces to achieve the Swedish rust removal standard of Sa2.5 grade. When applying epoxy primer, it is necessary to add a dedicated curing agent and thinner, mix thoroughly, and let it stand for about 10 minutes. Apply the epoxy primer to achieve the specified film thickness, which can be done by spraying or brushing, and allow it to dry completely after 24 hours. For the topcoat, fluorocarbon paint or polyurethane paint is mostly selected. Apply the topcoat to achieve the specified film thickness, and allow it to dry completely after 24 hours.
