Description
Ortho Resin Boat Grade 43.00
espol™ is the brand name / trademark of the unsaturated polyester resin processed at Satyen Polymers. Our resins are tailor made to meet the diverse needs of GRP/FRP industry. espol™ compiles with requirements of companies interested in improved efficiency and superior performance of their finished product.
PRODUCT FEATURES & BENEFITS
espol™ 43.00 Ortho Marine / sanitary grade is a quick-curing superior phthalic anhydride glycol based unsaturated polyester resin for general purpose applications. It is neither waxed nor pre- accelerated and suitable for both hand lay- up application and gun spray application. However, gun spray- up application is preferable because it can apply the resin evenly and spreading a thin coat without any pinholes This grade is approved by Indian Register of shipping ( IRS) for the fabrication of fishing Trawlers espol™ 43.00 resin coated surface is glossy after cured. It has good mechanical properties and water resistance and is resistance to mild chemicals and ultra- violet light, thus enhancing the durability of glassfibre reinforced plastics (GRP)
products. Besides, the time between gealtion and cure is short for espol™ 43.00 resi and espol™ 20.00 gelcoat and therefore
productivity can be increased.
TYPICAL APPLICATIONS
• Fishing Trawlers/speed boats/ sanitary Mouldings for kitchen/bath

* When post cured after maturation
USAGE
The Superior ortho marine/sanitary polyester resin performs best if the laminate is completely cured. The quantity of catalyst
and accelerator can be adjusted to get a shorter or longer gel time.
It is recommended to mature the products for 24 hours and post curing should be done for minimum of three hours at 80 deg
cent, and 2/3 weeks at or more 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 41.00 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 kgs ) and epoxy coated steel drums HDPE barrels ( 225 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.
