UPR-Unsaturated Polyester Resin For Car Putty,body

M23 Unsaturated Polyester Resin for producing Body Fillers and Car Putties of car body repairing ______________________________________________________________________________________ DESCRIPTION: M23 is a high molecular weight unsaturated modified ortho-terephthalic polyester resin especially designed for use in the manufacture of body fillers and other putties for Methyl ethyl peroxide cure. Its toughness properties is designed and chemically balanced to substantially reduce the internal and external cure cracks of the patch compounds. It has also excellent shelf life at ambient temperature below 30 centigrades. ______________________________________________________________________________________ USES: M23 is recommended for use in the following: Body Fillers Car Putties Use Methyl Ethyl Peroxide as hardener.______________________________________________________________________________________ FEATURES AND BENEFITS: Excellent adhesion to metal. High reactive and resilient High impact resistance. Excellent ambient stability Tough-flexible polyester resin.Good scratching performance, Excellent resistance to temperature changing, ______________________________________________________________________________________ PACKAGING: M23 is packed in steel drums of standard size at 220 kilograms net weight. ______________________________________________________________________________________ TYPICAL PROPERTIES:These values are typical and should not be construed as quality control specifications. Liquid Resin Properties Properties Values Color light yellow transparent liquid Non-volatile matter 64-68 % Acid Value 22-28 mg/KOH/g Viscosity at 25 centigrdes 90-110 s Geltime at 30 centigrades 3-5 minutes Peak Exothermic at 25 centigrades 150-165 centigrades Density at 25 centigrades 1.10±0.05 gram/cc Stability below 30 centigrades 12 months minimum These are laboratory properties at the end of the batch production. Geltime and Peak exotherm are measured by adding 2.00-g MEKP50 Hardener and 0.8 grams cobalt (10%) per 40-grams resin. ______________________________________________________________________________________ SUGGESTED APPLICATION GUIDELINES: In order to achieve maximum filler capacity of the resin without drastically increasing the viscosity of the resulting putty compound, it is advised to use fillers of varying particles size. Suitable extenders are talc, crystalline chalk or calcium carbonate and barytes with low iron content. Talc is applied as the main component because it improves sanding properties. ______________________________________________________________________________________ RECOMMENDED STORAGE CONDITIONS: Store indoor in a dark area which is not exposed to moisture at a temperature not exceeding 30° C. Keep container sealed to prevent moisture pick-up and monomer loss. Rotate stocks as much as possible. Follow FIRST-IN-FIRST-OUT RULE. M23 remains stable for a minimum of 12 months provided proper storage conditions are followed. Shelf life deteriorates at high temperatures especially when exposed to direct sunlight. ______________________________________________________________________________________ MATERIAL SAFETY HANDLING INFORMATION: M23 resin contains ingredients which could be harmful if mishandled. Contact with skin and eyes should be avoided and necessary personal protective equipment and clothing should be worn, such as chemical gloves, gas mask, eye goggles and apron. Keep away from heat, source of ignition. Himens has Material Safety data Sheets (MSDS) for each of its products.
