1. Automobile scraping ash is putty and curing agent. Putty, commonly known as putty, also known as unsaturated polyester resin putty, is a rapidly developing new filling material, which can adhere to the surface of objects well and does not produce cracks when drying.

2. Usage: Scrape off oil stain, rust, old paint film and moisture on the surface, and confirm drying and polishing. Mix the main ash and curing agent evenly (with the same color) according to the weight ratio of 100: 1.5 ~ 3, and use it up within the gel time (the gel time of putty is generally 5 minutes-15 minutes). The lower the temperature, the more curing agent is used, but generally it should not be greater than 100: 3. Scrape the prepared putty on the polished two-component primer or pretreated board surface with a scraper. If a thick layer is needed, it is best to scrape it several times to achieve the required thickness. If bubbles penetrate during coating and scraping, they must be completely scraped off with a scraper to ensure good adhesion. Generally, 0.5 ~ 1 hour after scraping is the best wet grinding time (polishing with water mill, and painting can only be carried out after the water vapor dries out). 2 ~ 3 hours is the best dry grinding time. After grinding, the dust on the surface can be removed, and subsequent operations such as painting, topcoat and varnish can be carried out. For occasions with high requirements, it is necessary to scrape putty (red ash and filler ash) to fill tiny defects after polishing putty, then spray the display layer and polish it to check tiny defects, and then carry out subsequent spraying.
