PLIOGRIP P-888 ISOPHTHALIC FIRE RETARDANT RESIN
. GENERAL DESCRIPTION
PLIOGRIP P-888. Is a low flammability unsaturated polyester resin based on Isophthalic acid, formulated with antimony compounds in synergestic effect with chlorine compounds. Glass reinforced plastic moldings made from PLIOGRIP P-888 resin have excellent properties like water resistance, heat resistance, chemical resistance along with fire - retardant characteristics.
PLIOGRIP P-888 resin finds exclusive applications where good mechanicals, chemical along with good fire retardant properties are required.

(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.
NOTE :
The above information given for general guidance for the use of our Product, keeping in view the variable operating/process conditions and methods, it is recommended that each consumer evaluates the suitability of the products. The company does not accept any responsibility whatsoever for any damage, injury or loss resulting from the use of above information.
METHOD OF TEST : THE METHOD OF TEST AND TOLERANCES ARE AS PRESCRIBED IN BS: 3532: 1962, BS:2782 : 1957 AND IS 6746 : 1972.
