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 or it can’t be used.
2、 Burnishing keelson before scratching. 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.
3、 Prohibit using the bad quality thinner to dilute this product. Otherwise it will generate like bubbling, peeling off, badly descending adhesive force, and other questions.
4、 Temperature is lower or the humidity is higher, the firming time will prolong. The consistence and gelation time (pot life) of putty may adjust according to the requirements of customers.
5、 Its quality can be guaranteed for 4 months since the date of its production. If it does not beyond this period, it can be used continuously.
Packing and Storage:
Main ash: 1L, 4L printing iron drums. Firming agent: 25g, 100g plastic tubes.
Storage Condition: 5-35 degree centigrade, store in a cool, dry well-ventilated place.
