PLIOGRIP P446 ISOPHTHALIC SMC/DMC POLYESTER RESIN
PLIOGRIP P 446 is a rigid and highly reactive Isopthalic acid based polyester resin specifically designed for SMC/DMC application. Pliogrip P446 posses high reactivity which allow high filler loading. The functionality in PLIOGRIP P446 is adjusted to provide an optimum thickening behaviour. The resin has a high SPI peak exotherm and low cure time that allow faster production rate.
The moulding made from PLIOGRIP P446 provides superior chemical resistance, mechanical strength, toughness & heat resistance.PLIOGRIP P446 is suitable for most SMC/DMC – standard and fire retardant formulation.

(The specimens for testing are cured for 24 hours at Room temperature followed by Post Curing for 4 hours at 80°C)
POST CURING REQUIREMENTS:
Satisfactory laminates for many applications can be made by curing the laminate at ambient temperatures. However for achieving optimum properties the laminate should be post cured for a period of 4 hours at 80°C. The post curing is most effective when carried out immediately after the 24 hours ambient temperature cure.
Storage & Handling :
Should be stored in closed containers in cool conditions away from direct Sunlight. Resins exposed to direct Sunlight may lead to premature gelation even in the absence of a Catalyst. Shelf life of Resin @ 25°C. about 6 months from the date of manufacturing.
Most of our resin contain styrene monomer and are classified as highly flammable liquids. Working areas should be well ventilated since styrene has a threshold value of 1000ppm in normal working atmosphere .It is also an eye skin irritant. Hence, Goggles and gloves are recommended while handling our Resins
Caution:
Pliogrip Q 8013 MEKP should never be mixed with Pliogrip S 1021 Cobalt, as this would cause explosion. The Pliogrip S 1021 Cobalt should be blended into the resin first. The Pliogrip Q 8013 MEKP should be added just before use.
