1. alkyd resin coatings are inexpensive, cost-effective and easy to use. It doesn't take many years of experience to operate alkyd coatings well.

2. Due to the low surface tension of most alkyd coatings, solvent-based alkyd coatings are less affected by film defects in various coatings, so there are basically no defects such as edge shrinkage and shrinkage caused by surface tension-driven flow or surface tension difference-driven flow.

3. The disadvantages of alkyd resin are poor baking color retention and limited outdoor durability, so it is difficult for solvent-based alkyd coatings to achieve high solid content.

4. Another fatal disadvantage is that alkyd paint will produce smoke in the oven, which will cause great pollution to the air and does not conform to the modern environmental protection concept.
