requirment of unsaturated polyester resin

RFQ Description

We owe your reference through reliable sources.We are in requirement of Unsaturated Polyester Resin. We are an Tiles manufacturing company, and our use is for the ceramic purpose for bonding of the ceramic material with each other temperature in the Kiln would be in range of around 100-150 degree Celcius.Sending herewith the production specification as required by us.Orthophthalic unsaturated Polyester resin having medium viscosity, moderate resilience and low reactivity based on Orthophthalic acid and standard glycols, dissolved in styrene monomer. It is specially designed for Quartz marble applications.TYPICAL LIQUID RESIN PROPERTIES:Appearance : Clear color less liquidViscosity at 25eg;C (cP) : 400 to 800Acid Value (mg KOH/gm) : 25maxSpecific Gravity at 25: 1.11 to 1.13Volatile content (%) : 34Gel time at 80eg;C(with Resin = 100 grams; Accelerator 3% Cobalt Octoate = 0.6mlCatalyst Trignox 21S = 0.6mlT68 to T80 (minutes) : 4 to 10T80 to TPeak (minutes) : 5 to 10Peak Exotherm : 230maxVolume Shrinkage (%) : 7.5maxShelf Life at 25eg;C (months) : 3Note:- Gel time will vary with temperature and the amount of accelerator andcatalyst usedTYPICAL PROPERTIES OF CUREDCLEAR CAST RESIN:The test specimens were cured for 24 hours at room temperature and subsequently post cured at 80eg;Cfor four hoursBarcol hardness : 45Heat deflection temperature : 63Tensile strength (kg/cm2) : 550Tensile modulus (Mpa) : 3000Elongation at break (%) : 2.2Flexural strength (kg/cm2) :1100Flexural modulus (Mpa) : 3300Water absorption @25eg;C (mg) : 18(after 24hours)CURING CONDITIONS :The specimens for testing of mechanical properties are prepared by curing the resins with 0.5 mlAccelerator (3% cobalt content) and 1.0 % MEKP catalyst, added to 100 gm. of resin. The specimens are cured for 24 hours at room temperature followed by post curing for 4 hours at 80Ãĕquest;rac12;ÃÂeg;C.STORAGE & SHELF LIFE :It should be stored in a cool and dry place away from sunlight and other sources of heat, preferably below 25eg;C. At higher storage temperatures, the shelf life decreases sharply. Presence of moisture also affects the storage life of the resin leads to turbidity in the resin. It should be guaranteed for 6 months from the date of manufacture provided the resin is stored at normal room temperature.METHOD OF TESTINGIS-6746-1994, ASTMParshwa Industries,Opp Peoples Co-Op.
