Journal of Applied Polymer Science, 1990
AbstractA new series including eight structurally different self‐curing epoxy compounds bearing azomethine linkages were synthesized, characterized and polymerized. 4‐(2,3‐Epoxypropoxy)‐benzaldehyde (EPB) or 2,3‐epoxypropyl glyoxylate monohydrate (EPG), prepared by reacting 4‐hydroxybenzaldehyde or glyoxylic acid monohydrate, respectively, with excess ...

Epoxy molding compound for fingerprint sensor
2016 International Conference on Electronics Packaging (ICEP), 2016The fingerprint sensor is promising as a personal identification method for the devices. For downsizing and the cost reduction of the fingerprint sensor, capacitance method is main stream for the portable devices such as Smartphone's. Conventionally, expensive sapphire glass has been used as insulating layer of fingerprint sensor, but sapphire glass is

Epoxy Compounds for Immobilizing Radioactive Wastes
Atomic Energy, 2005The radiation resistance of epoxy compounds, solidified by crystalline hardening agents - metaphenyl-enediamine and phthalic anhydride - is investigated. It is shown that under conditions of γ irradiation (E = 1.33 MeV) the temperature of vitrification of the compounds depends on the dose (doses up to 1500 Mrad were investigated) and temperature 20–160°

Ablation resistance of certain epoxy compounds
Polymer Mechanics, 1972The rate of ablation in oxidative and inert media at flow velocities up to 200 m/sec has been investigated for certain epoxy compounds containing powdered copper and zinc dust. The causes of ablative destruction and the factors tending to improve the ablation resistance are examined.

Thermophysical analysis of plasticized epoxy compounds
Journal of Engineering Physics, 1973A study has been made concerning the effect of dibutylphthalate and thiocol plasticizers in various concentrations on the structure as well as the thermophysical and the mechanical properties of grade ED-5 epoxy resin. It is shown that the entire complex of analyzed thermophysical properties changes appreciably, depending on the kind and on the ...

Some experiences with epoxy resin grouting compounds
American Industrial Hygiene Association Journal, 1980Epoxy resin systems are used in tiling and grouting in the construction industry. Because of the nature of the application, skin contact is the primary hazard. The most prevalent reaction was reddening of the forearms, followed by whole body reddening and loss of appetite, these latter two being associated with smoking while applying the resin.

Acta dermato-venereologica. Supplementum, 1992
Of a total of 3731 patients investigated between 1974 and 1990, 1844 (49.4%) had an occupational skin disease. Of them 142 (7.7%) had an occupational skin disease caused by epoxy compounds--135 patients (95%) had allergic contact dermatitis, five had irritant contact dermatitis, and two had contact urticaria. Apart from dermatoses, two patients had IgE-

Aliphatic-Cycloaliphatic Epoxy Compounds and Polymers
2007Aliphatic-cycloaliphatic epoxy compounds (ACECs) contain different epoxy groups in the molecule: glycidyl, i.e. 2,3-epoxypropyl groups, and cycloaliphatic, i.e. 1,2-epoxycyclopen-tane or 1,2-epoxycyclohexane rings. The epoxidation of double bonds in cycloolefins was carried out using aqueous peracetic acid (PAA).
