Description

General description

Predominantly cis 1,2-cyclohexanedicarboxylic anhydride (HHPA) is a cyclic anhydride that can be used for a variety of applications such as: plasticizer, rust inhibitor, and a curing agent for epoxy based resins.

Application

HPPA, in combination with triethaylamine (TEA), can be used as a polymerization initiator in the preparation of polyester based resins. It can also be used as a hardener to cure 1,4-butanediol diglycidyl ether which can be used as an epoxy based system for electronic devices.

Organic acid anhydrides (OAAs) are highly allergenic compounds used in the chemical industry. The OAAs probably act as haptens but the proteins that form conjugates with OAAs in vivo are still unknown. Conjugates between the anhydrides and serum albumins (SAs)

Shear horizontal guided wave modes to infer the shear stiffness of adhesive bond layers.

This paper presents a non-destructive, ultrasonic technique to evaluate the quality of bonds between substrates. Shear-horizontally polarized (SH) wave modes are investigated to infer the shear stiffness of bonds, which is necessarily linked to the shear resistance that is a
