| PRODUCT FEATURES & BENEFITS: |
| |
espol™ 32.00 a medium viscosity, medium reactive polyester resin based on Terephthalic acid and superior glycols It exhibits good mechanical and electrical properties together with good chemical resistance compared to general-purpose resins. espol™ 32.00 rapidly wets the surface of glass fiber in the form of cloth mat or chopped fiber to produce laminates and moldings.
espol™ 32.00 an ideal choice for making glass reinforced, storage tanks, tankers, ducting, hoods etc. for handling chemicals at ambient temperature as a lining UP resin for PVC/PP gl composite product.

| USAGE: |
| Chemical Resistance : |
Un reinforced castings of espol™ 32.00 show a commendable degree of resistance to most inorganic and organic acids at ambient temperature, with the exception of strong oxidizing acids. It also resists oils, plasticizers and inorganic salt
solutions. lt is not recommended for strong acids/alkalies For specific application please contact our technical services department. |
| |
| |
| HEAT RESISTANCE: |
| |
The dry heat resistance of espol™ 32.00 resin is many superiors to general-purpose orthophthalate resin. |
| |
| |
| USAGE : |
| |
The TPA (Mech Grade) polyester resin performs best if the laminate is completely post cured. The qualities of catalyst and accelerator can be adjusted to get a shorter or longer gel time. Accelerator must be completely mixed before catalyst is added in order to avoid a direct blending which may cause an explosion |
| |
| |
| POST CURING: |
| |
It is recommended to mature the products for 24 hours and post curing should be done for minimum of five hours at 800C, or 2-3 weeks at room temperature. This is essential for getting the optimum properties. |
| |
| STORAGE / HANDLING: |
| |
| The polyester resin remains stable for 3 months at 300C in the dark and 4 months at 250C. The resin stability deteriorates markedly at elevated temperature, especially when exposed to direct sunlight.
espol™ 32.00 has a flash point of 340C and is classified as flammable. "NO SMOKING " rules should be strictly followed. In case of spillage, use sand or earth to absorb and shovel off for disposal as per local regulations, In case of fire, use dry chemical foam, Carbon dioxide or water spray to extinguish the flame. |
| |
| PACKING: |
| |
The Polyester resin is packed in HDPE carboys ( 30, 35, 40 & 45 kgs ) and epoxy coated steel drums HDPE barrels
(220 kgs) of standard size net weight. Special packing size offered for projects on returnable containers. Technical services are also provided to comply standards. |
| |
| HEALTH & SAFETY: |
| |
Never add metal salts (Accelerator) or Pre Acceleratorated resin to Peroxides when adding peroxides to a resin solution, mix thoroughly the resulting product Do not add organic peroxides to a hot diluents or process. Prevent contamination of Acclerator, promo0ter from materials like ( Iron Copper, Cobalt ) salts, storing acids and sanding dusts. Suggested containers are glass, polypropylene, Teflon, Poly-ethylene or stainless steel to prevent contamination of material during its handling.
