Description:205# High Temperature Polyester Putty Ingredients: Unsaturated polyesters resins for resistance high temperature, modified resin, color pigment, stuffing, anti sediment materials, auxiliary agent and firming agent mixing ratio 100:2. Characteristics: Good scratching performance, excellent resistance to temperature changing, outstanding adhesive force and elasticity. It has resistance to some certain of baking. It is 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 techniques of passenger car to satisfy the leveling and smoothness of the keelsons before painting the surface. It is also of good repairing for glass reinforced plastics. Item Index and Testing Standard: Outward appearance: the color is unanimous, and there are no visible particles by naked eye. Visual examination Air drying: meet the customers requirements, GB/T1728-79 Consistency: 9-12cm (except for the specialties), GB/T1749 Scratching performance: good handling, no curling (suitable for the scratching of board) Burnishing performance: burnishing is not very easy Resistance to high temperature: there is no bubbling and cracking under baking at 160 degrees Centigrade after drying There is no bubbling and cracking under baking at 100 degrees Centigrade after gelling Pliability less than 100mm, GB/T1748 Impact strength: more than 8kg.cm (25kg.cm, not falling off), GB/T1732 Adhesive force: more than 50kg/1.2cm2, GB/T5210 Reference for construction: 1. Evenly mix the main ash and firming agent with the proportion being 100:2 (makes 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. 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 (pot life) 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. (If it does not beyond this period, it can be used continuously).
