| |
| USAGE: |
| |
The general purpose 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 as per requirements for getting the optimum properties.
|
| |
| STORAGE / HANDLING: |
| |
| The polyester resin remains stable for 2 months at 250C in the dark and 3 months at 250C. The resin stability deteriorates markedly at elevated temperature, especially when exposed to direct sunlight.
espol™ 12.05 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, promoter 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.
