{"product_id":"polytek-polypurge-dry-gas-blanket","title":"Polytek PolyPurge Dry Gas Blanket - Shelf Life Extender for Urethane Liquids, 10 oz","description":"\u003cp\u003eOnce a container of polyurethane part A or part B has been opened, the humid air sitting on top of it is the problem. Moisture reacts with the isocyanate side, and the next pour comes out foamy, full of bubbles or soft. PolyPurge is Polytek's answer: a dry, heavier than air gas you spray into the container right before the lid goes back on. It sinks onto the liquid, pushes the damp air out of the way, and extends the shelf life of whatever is left in the can.\u003c\/p\u003e\n\u003cdiv class=\"bs-spec-block\"\u003e\n\u003c!--bs-body-v1--\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003ctable class=\"bs-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eType\u003c\/th\u003e\n\u003ctd\u003edry gas blanket in an aerosol can, nonflammable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eUse with\u003c\/th\u003e\n\u003ctd\u003eopened polyurethane part A and part B: urethane mold rubbers, casting plastics and two part pour foam\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eGas\u003c\/th\u003e\n\u003ctd\u003e1,1,1,2-tetrafluoroethane (HFC-134a), heavier than air, no ozone depleting materials\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eNet contents\u003c\/th\u003e\n\u003ctd\u003e10 oz (283 g) per can, with an extension nozzle for narrow openings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSizes\u003c\/th\u003e\n\u003ctd\u003esingle can, case of 12 cans\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eUse class\u003c\/th\u003e\n\u003ctd\u003eindustrial and professional use only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eShipping\u003c\/th\u003e\n\u003ctd\u003eUN1950 Aerosols, Division 2.2, limited quantity.
