Is Automotive Putty Prone to Falling Off?
1 Answers
Automotive putty applied on the outer layer with subsequent paint is not prone to falling off. However, without the protection of outer layer paint, it can easily fall off when exposed to water. Below is the relevant introduction: 1. Function: Automotive putty is used in car painting on the first or second primer after sanding to fill small defects, dents, scratches, or other processing marks, creating a smooth surface for the next coat of paint. 2. Characteristics: It has a high content of pigments and fillers, is thick and easy to dry, becomes hard and fine after drying, and is easy to sand. It is commonly available in water-based and oil-based types. Oil-based putty is further divided into alkyd, nitrocellulose, perchloroethylene, epoxy, and other types, with nitrocellulose (currently modified with acrylic) being the most commonly used.
