Detailed Product Description
2308# polyester putty apply in manufacture of bus and machine Ingredients: Unsaturated polyesters resins, 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. 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. It is also of good toolability for glass reinforced plastics. Main technical standard: Outward appearance: The color is unanimous, and there are no visible particles by naked eye. Air drying: Meet the customers' requirements . Consistency: 9-12cm (except for the specialties). Scratching performance: Good handling, no curling (suitable for the scratching of board) Burnishing performance: Burnishing easy, extraction powder is fast. Resistance to high temperature: There is no bubbling and cracking under baking at 140 degree centigrade after drying. There is no bubbling and cracking under baking at 80 degree centigrade after gelling Resistance to high and low temperature changing: More than two cycles . Pliability: Less than 50mm. Impact Strength: More than 15kg.cm (or 35kg.cm Not falling off). Adhesive force: More than 50Kg/1.2cm2. 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.The mixture of putty and hardener must not put return into the can. 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.The storage life is six months from the date of production (if it is beyond the storage life, please confirm according to the standard inspection; if the quality is still ok, you can used it continuously).
