PLIOGRIP P-668 NPG IS0PHTHALIC GELCOAT RESIN
GENERAL DESCRIPTION
PLIOGRIP P-668 is a standard thixotropic gel coat based on Isophthalic Acid and Neopentyl Glycol. It is suitable for Marine, Automobile and Culture marbel applications. Due to its high molecular weight and unique molecualr structure it has an outstanding water resistance and chemical corrosion resistance properties. PLIOGRIP P-668 NPG Isophthalic Gel coat confers on the end products all round improved performance such as better colour, stability, surface gloss, better weather durability, improved heat resistance, better scratch resistance, reduced porosity etc. PLIOGRIP P-668 NPG Isophthalic Gel coat have very low water absorption and remains, practically unaltered on contact with water.
Due to better scratch resistance than conventional gel coats products such as boat hulls, decks and sanitary wares made with NPG gel coat maintain their aesthetic look for an extended period of time.

(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.
