| PRODUCT FEATURES & BENEFITS: |
| |
| The general purpose polyester resin espol™ 15.00 is a quick curing unsaturated polyster resin based on Orthophthalic raw material for laminating purpose. It is un-acclerated. Suitable for both hand lay up and gun spray up. The resin offers excellent mechanical properties, impact and water resistance. The glassfibre laminate made with this resin has excellent mechanical strength, good rigidity and outstanding durability. The pre-accelerated known as GP that is graded as espol™ 12.00. |

| |
| USAGE: |
| |
The general purpose polyester resins performs best if the laminate is completely post cured. The quantity of catalyst and accelerator can be adjusted to get a shorter or longer gel time. |
| |
| |
| POST CURING: |
| |
It is recommended to mature the products for 24 hours and post curing should be done for minimum of three 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™ 15.00 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 Accelerator, promooter 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.
