Characteristics:
Good scratching performance, excellent resistance to temperature changing, outstanding adhesive force and elasticity. Resistance to some certain of baking. Mainly being applied to the leveling up and decoration of the blemishes, such as the drop pits of keelsons, pin-shaped cavities, crackles, and little welding lines etc. Before closing the floating coat in the painting technics of passenger car to satisfy the leveling and smoothness of the keelsons before painting the surface.

Reference for construction:
1. Evenly mix the main ash and firming agent with the proportion being 100: 2 (make the color unanimous), and using up them within the gelation time.

2. Scratch the putty which has already finely mixed on the primer paint of double components after burnishing or the surface of cold-rolled sheet which has already been finished processing. If the thickly scratching is required, you had better thinly scratch for many times to meet the required thickness. If some air bubbles infiltrate while scratching, you should thoroughly strickle it by means of scraper, so as to ensure the good adhesive force. The best wet milling time is 0.5-1h after scratching (As for wet milling polishing, paint-spraying should be done after the water vapor dries out). 2-3h is the best dry milling time.

Notes:
1. Cover it after using in case that the impregnant volatilization may result in the deterioration of main ash.

2. The solidifying period of coating film will extend if the temperature is high or low. The consistence and gelation time (pot life) of putty may adjust according to the requirements of customers.
3. This product is unsuitable for directly scratching on galvanization plates.
