•C12-C14 alkyl glycidyl ether •XZ 92486.00 developmental epoxy resin
•CAS No. 068609-97-2 •CAS No. 030499-70-8
•EC No. 271-846-8 •Trimethylolpropane-epichlorohydrin copolymer
Product Overview
•Reactive diluents are clear, colorless, low-viscosity, liquids that are blended with epoxy resins to improve cure. See Product Description.
•Reactive diluents are used in applications such as civil engineering, structural composites, and marine and protective coatings.See Product Uses.
•Skin exposures to reactive diluents can cause irritation and allergic skin reactions. If liquid or vapor contacts the eyes, irritation may result. Excessive inhalation of vapor may cause
respiratory irritation. See Health Information or Physical Hazard Information.
•Those working with reactive diluents in manufacturing operations could be exposed during maintenance, sampling, testing or other procedures. See Exposure Potential.
•Reactive diluents are stable under recommended storage conditions. However, they should be kept from contact with oxidizing materials, acids, bases, and amines, as well as from
excessive heat. Physical Hazard Information.

Manufacture of Product
•Capacity1 – Dow is one of the world's largest producers of epoxy resins and intermediates.
Dow produces epoxy glycols and reactive diluents in the following locations: Freeport, Texas, USA; Pisticci, Italy.
•Process – Reactive diluents are prepared by reacting epichlorohydrin (CAS No. 106-89-8) with either C12-C14 alkanol (dodecanol – tetradecanol) to make C12-C14 alkyl glycidyl ether, or trimethylolpropane.

Product Description2
Reactive diluents are clear, colorless, low-viscosity liquids that are blended with epoxy resins to enable them to be cured into flexible, tough materials. Compared to typical curing techniques, reactive diluents allow the epoxy resin to be less viscous (“syrupy”). This improves surface
wetting and adhesion. Epoxies that have reactive diluents added exhibit longer “pot life” (usable mixing time) than epoxy resins without diluents. Reactive diluents exhibit a mild ether-like odor.  Dow produces two reactive diluents:
•C12-C14 alkyl glycidyl ether (CAS No. 068609-97-2, EC No. 271-846-8)
•XZ 92486.00 developmental epoxy resin (trimethylolpropane-epichlorohydrin copolymer, CAS No. 030499-70-8)

Exposure Potential4,5
Reactive diluents are used in the production of a variety of industrial and consumer products. Based on the uses for these resins, the public could be exposed through:
•Workplace exposure – Exposure can occur either in a reactive diluents manufacturing facility or in the various industrial or manufacturing facilities that use reactive diluents.
Reactive diluents are produced, distributed, stored and consumed in closed systems. Those working with reactive diluents in manufacturing operations could be exposed during
maintenance, sampling, testing or other procedures. Each manufacturing facility should have
a thorough training program for employees, appropriate work processes and safety
equipment in place to limit unnecessary exposure to reactive diluents. See Health Information. •Consumer exposure to products containing reactive diluents – Dow does not sell these reactive diluents for direct consumer use. Reactive diluents are used in many epoxy resins that can be used in a wide variety of applications that could permit consumer exposure. For instance, some epoxy resins are approved to make coatings for food packaging applications in the U.S. and Europe. Although reactive diluents are used to make many materials that consumers could contact, there would be little to no unreacted glycol epoxy remaining in the final product. See Health Information.
•Environmental releases – In the event of a spill, the focus is on containing the spill to prevent contamination of soil, surface or ground water. If irritating vapors are present, an
approved air-purifying respirator with organic vapor canister is recommended for cleaning up spills and leaks. For small spills, reactive diluents should be absorbed with sand. Reactive diluents are expected to be harmful aquatic organisms. See Environmental, Health and
Physical Hazard Information.
•Large release – Industrial spills or releases are infrequent and are generally contained. If a large spill does occur, the material should be captured, collected and re-processed, or
disposed of according to applicable governmental requirements. An approved air-purifying respirator with organic vapor canister is recommended for emergency work. In case of fire, deny any unnecessary entry into the area. Use dry-chemical or carbon dioxide fire
extinguishers, or foam. Alcohol-resistant foams are preferred, although general-purpose
synthetic foams or protein foams may work. Use of a direct water stream may spread fire.
Firefighters should wear positive-pressure self-contained breathing apparatus (SCBA) and protective clothing. Firefighters should also avoid contact with these materials. Products of combustion may be toxic and/or irritating. Follow emergency procedures carefully. See
Environmental, Health and Physical Hazard Information.

Health Information6,7
C12-C14 Alkyl Glycidyl Ether
Repeated or prolonged skin contact with C12-C14 alkyl glycidyl ether can produce skin irritation – even a mild burn – or an allergic reaction. Prolonged skin contact is unlikely to result in absorption of harmful amounts.
If C12-C14 alkyl glycidyl ether vapor or liquid contacts the eyes, slight temporary irritation may result, evidenced by discomfort and redness. Corneal injury is unlikely.
Excessive exposure to C12-C14 alkyl glycidyl ether vapor may cause irritation to the upper respiratory tract (nose and throat).
C12-C14 alkyl glycidyl ether has low toxicity if swallowed. Small amounts swallowed as a result of normal handling activities are unlikely to cause injury.
XZ 92486.00 Developmental Epoxy Resin
Prolonged skin contact with XZ 92486.00 developmental epoxy resin can produce skin irritation and redness or an allergic reaction. Prolonged or widespread skin contact may result in absorption of harmful amounts.
If XZ 92486.00 developmental epoxy resin vapor or liquid contacts the eyes, moderate irritation may result and moderate corneal injury is possible.
Excessive exposure to XZ 92486.00 developmental epoxy resin vapor may cause irritation to the upper respiratory tract (nose and throat).
XZ 92486.00 developmental epoxy resin has low toxicity if swallowed. However, ingestion may result in mild burns to the mouth and throat or gastrointestinal irritation or ulceration.
For more information, see the relevant Safety Data Sheet (SDS).

Environmental Information8
C12-C14 Alkyl Glycidyl Ether
C12-C14 alkyl glycidyl ether is expected to be moderately biodegradable.  Inadvertant releases to aquatic environments may result in adverse effects to aquatic organisms.  The potential for C12-C14 alkyl glycidyl ether to bioaccumulate is moderately low.
XZ 92486.00 Developmental Epoxy Resin
XZ 92486.00 developmental epoxy resin is expected to degrade slowly in the environment. Inadvertant releases to aquatic environments may result in adverse effects to aquatic organisms. The potential for XZ 92486.00 developmental epoxy resin to bioaccumulate is low.
For more information, see the relevant Safety Data Sheet.

Physical Hazard Information9,10,11
reactive materials studiesReactive diluents are stable under recommended storage conditions. However, elevated temperatures can lead to degradation and gradual build-up of viscosity.
These products should be kept from contact with oxidizing materials, acids, bases, and amines. Contact of more than 0.5 Kg (1 pound) with aliphatic amines can cause irreversible polymerization with considerable build-up of heat.
For more information, see the relevant Safety Data Sheet.

Regulatory Information
Regulations may exist that govern the manufacture, sale, transportation, use and/or disposal of reactive diluents. These regulations may vary by city, state, country or geographic region. Information may be found by consulting the relevant Safety Data Sheets, Technical Data Sheets
