The performance of coatings can be divided into:
Open-can appearance and low-temperature freeze-thaw properties of coatings;
The construction method and performance of the coating: brush coating, roller coating, spray coating, and construction feel and leveling performance, etc.
Appearance of coating film: such as gloss, fullness, color and fineness.
Drying time: surface dry time, solid dry time, recoat time, maintenance period.
Adhesion: Adhesion to the substrate or to the old paint film.
Covering power: After normal brushing times, whether to cover the bottom.
Mechanical properties: hardness, impact, flexibility.
Resistance: UV resistance, chemical resistance, abrasion resistance, water and alkali resistance, mold and algae resistance, etc.
Durability: Whether it has long-term gloss and color retention.
Storage stability: sedimentation tendency, viscosity stability, etc.
