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’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、 Once the putty mix firming agent, don’t put it into can 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 high or low. The consistence and gelation time of putty may adjust according to the requirements of customers’.
3、 This product is unsuitable for directly scratching on galvanization plates.
4、 Its quality can be guaranteed for 6 months since the date of its production. I(f it does not beyond this period, it can be used continuously).
