Midland, MI 48674 Emergency Phone: 517-636-4400 <br />Product Code: 19217 Page: 2 <br />PRODUCT NAME: D.E.N. (R) 438 EPDXY NOVOLAC <br />Effective Date: 03/12/87 Date Printed: 06/30/87 MSDS:000216 <br />3. FIRE AND EXPLOSION HAZARD DATA: (CONTINUED) <br />FIRE AND EXPLOSION HAZARDS: None known. <br />FIRE -FIGHTING EQUIPMENT: Wear positive pressure, self-contained <br />breathing apparatus. <br />4. REACTIVITY DATA: <br />STABILITY: (CONDITIONS TO AVOID) Excessive heating over long <br />periods of time degrades the resin, increases viscosity and <br />epoxide equivalent weight. <br />INCOMPATIBILITY: (SPECIFIC MATERIALS TO AVOID) Acids, bases, <br />and amines. <br />HAZARDOUS DECOMPOSITION PRODUCTS: The by-products expected in <br />:= incomplete pyrolysis or combustion of epoxy resins are <br />mainly phenolics, carbon monoxide and water. The thermal <br />decomposition products of epoxy resins therefore should be <br />treated as potentially hazardous substances, and appropriate <br />Precautions should be taken. <br />HAZARDOUS POLYMERIZATION: Unlikely to occur by itself, but masses <br />of more than 1 pound of product plus an aliphatic amine will <br />cause irreversible polymerization with considerable heat <br />buildup. <br />5. ENVIRONMENTAL AND DISPOSAL INFORMATION: <br />ACTION TO TAKE FOR SPILLS: Soak up in absorbent material such <br />as sand and collect in suitable containers. Residual resin <br />may be removed using steam or hot soapy water. `Use of <br />methylene chloride or other solvents in cleanup poses a <br />distinct hazard and therefore should be avoided. Keep <br />spark producing equipment away. For large spills, evacuate <br />upwind of spills and contain with dike. <br />DISPOSAL METHOD: Resins can be disposed of through burning in <br />an adequate incinerator, or burying in a landfill, in accordance <br />(Continued on Page 3) <br />(R) Indicates a trademark -of The Doi Chemical Company <br />-2- <br />
