Shipment, Stora.ge, ndPrice. Butyrolactone is shipped in unlined steel tank cars and plain steel dmms. Plain steel, stainless steel, aluminum, and nickel are suitable for storage and handling mbber, phenoHcs, and epoxy resins are not suitable. Butyrolactone is hygroscopic and should be protected from moisture. Because of its low free2ing point (—44° C), no provision for heating storage vessels is needed. 

Nickel dialkyldithiocarbamates stabili2e vulcani2ates of epichlorhydrinethylene oxide against heat aging (178). Nickel dibutyldithiocarbamate [56377-13-0] is used as an oxidation inhibitor in synthetic elastomers. Nickel chelates of substituted acetylacetonates are flame retardants for epoxy resins (179). Nickel dicycloalkyldithiophosphinates have been proposed as flame-retardant additives for polystyrene (180—182) (see Flame retardants Heat stabilizers). 

Liquids. Approximately 170,000 railroad tank cars are used in the United States. The interior surfaces of these cars are tailored to carry a wide variety of products and are constmcted of steel which is either unlined or lined with materials to enhance the chemical compatibiUty with a specific product these lining materials include synthetic mbber, phenoHc or modified epoxy resins, or corrosion-resistant materials such as aluminum, nickel-bearing steel, or stainless steel. 

Elastomers, plastics, fabrics, wood and metals can be joined with themselves and with each other using nitrile rubber/epoxy resin blends cured with amines and/or acidic agents. Ethylene-propylene vulcanizates can also be joined using blends of carboxylated nitrile rubber, epoxy resin and a reactive metal filler (copper, nickel, cobalt). However, one of the largest areas of use of nitrile rubber modified epoxy systems is in the printed circuit board area [12]. 

The most frequent causes of allergic contact dermatitis in the United States include plants (poison ivy, poison oak, and poison sumac), metallic salts, organic dyes, plastic resins, rubber additives, and germicides.74 The most common skin patch test allergens found to be positive in patients along with potential sources of exposure are shown in Table 32.1.75 In patients with occupational contact dermatitis who were skin patch tested, the common allergens included carba mix, thiuram mix, formaldehyde, epoxy resin, and nickel.76... 

Major results. Figure 14.7 shows that the resistivity of aluminum-filled PMMA changes abruptly. Smaller volumes of filler contribute a little to resistivity but, after certain threshold value of filler concentration, further additions have little contribution. A similar relationship was obtained for nickel powder the only difference is in the final value of resistivity, which was lower for nickel due to its higher conductivity. The same conclusions can be obtained from conductivity deteiminations of epoxy resins filled with copper and nickel. Figure 14.8 shows the effect of temperature on the electric conductivity of butyl rubber filled with different grades of carbon black. In both cases, conductivity decreases with temperature, but lamp black is substantially more sensitive to temperature changes. Even more pronounced changes with temperature were detected for the dielectric loss factor and dissipation factor for mineral filled epoxy." ... 

With nonaqueous media, apparatus constructed of iron and lined with plastics, such as Teflon, Kel-F, Saran, polyvinyl chloride, polyesters, epoxy resins, or with stoneware, enamel, porcelain, glass, lead, nickel, Inconel, stainless steel, Hastelloy, Duriron, glazed tile, carbon brick, Karbate, titanium, tantalum, and zirconium can be used for the whole plant or specific apparatus.

Air entrapped during encapsulation and vapor from polymeric materials such as epoxy resin can cause corrosion. The corrosive effect of vapors from plastics, rubber, and wood on zinc and cadmium has been tabulated by Knotkova-Cermakova and Vickova (1971) other work, including electroplated zinc-nickel alloys, has been discussed by Donovan and Stringer... 

Contact sensitizers from a patient s own materials, such as formaldehyde, isothiazolinones, nickel, chromium, cobalt, colophony (in the form of resin acids), epoxy resin oligomers, reactive diluents, acrylates, methacrylates, polyamines and di-isocyanates, can be analyzed. In fact, any product can be analyzed, but it is not a routine task for laboratories and may be very expensive. There are two main reasons for chemical analyses. First, on patch testing, the patient is found to be allergic to a specific chemical, and the causative product(s) are analyzed for the chemical. Second, the patient s own material has caused an allergic test reaction, but MSDS or other information from the manufacturer did not reveal the causative chemical. In this case, it may be reasonable to analyze the material...
