Instructions:
1、 Evenly mix the main ash and firming agent with the proportion of 100：2 (make the color well-proportioned), and use 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’d 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.2-3h is the best dry milling time.
Notes:
1、 Don’t put them into cans once the polyester putty mix firming agent and 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 low or the humidity is high. The consistence and gelation time of putty can be adjusted according to the requirements of customers.
3、 This product is unsuitable for directly scratching on galvanization plates.
4、 Storage life: Its quality can be guaranteed for 6 months since the day of its production. (If it does not go bad beyond this period, it can be used continuously).
