Resin compound

Monoethano1 amine, diethanolarnine, and triethanolarnine have been cited in formulations for epoxy resins compounds (187—192). 

Polymer systems are now available which may be cured by reaction of epoxy resin compounds with the phenolic hydroxyl groups. Such reactions do not evolve volatile by-products. These materials are showing promise in the area of heat-resisting electrical insulation laminates.

This is used in manufacture of brake linings and is a polymer based on cashew nutshell liquid admixed with formaldehyde or furfuraldehyde and other ingredients. The polymerised resin mixture is cast into 8 cm thick slabs and then ground finely to produce the friction dust. Several fires have been experienced during bulk storage of the dust, attributed to autoxidation of the still partially unsaturated resin compound. Previously, linseed oil was used in place of the nutshell liquid, but fires were then more frequent. 

Other significant phenolic resin compounds include the mixture of urushiol variants, immunogenic compounds causing severe dermatitis from the Rhus spp. (poison ivy, poison oak and poison sumac).

A significant portion of the sulfur- and nitrogen-containing species in crude oil can be found in heterocyclic form within the asphaltene, maltene, and resin compounds. Oxygen-containing heterocycles may also be present. Examples of high-molecular-weight aromatic, resinous, and polar compounds found in crude oil are provided in TABLE 3-1. 

Distillate fuel fractions can contain naphthenic acids, sulfonic acids, and other hydrophilic compounds. If these hydrophilic compounds are present as sodium salts due to caustic washing of fuel, they become powerful emulsifying agents. Also, heavy resinous compounds in fuel can act to stabilize existing emulsions.

Resinoids mainly consist of nonvolatile, resinous compounds and are primarily used for their excellent flxative properties. 

Ion-Exchange Chromatography—employs, zeolites and synthetic organic and inorganic resins to perform chromatographic separation by an exchange of ions between the sample and the resins. Compounds which have ions with different affinities for the resin can be separated.

Holocellulose was isolated from bamboo powders by removing lignin and resinous compounds using alternate treatments of glacial acetic acid and sodium chlorite at 70-80 C for three hours according to the method of Ku and Chiou (20).

Black or dark brown daguerreo-type cases were very popular in the mid-1800s, and most consist of molded resin compounds combined with sawdust and pigment. Often identified as gutta percha or hard rubber, these composition cases are more britde than those materials. If chipped, the fresh surface of rubber or gutta percha will appear homogeneous and smooth, while the composition will be porous, mottled, and coarse. 

In order to produce harder, tougher materials, inventors combined plant resins with other plant and animal fluids, and inorganic materials such as diatomaceous earth, and pulverized glass, porcelain, or stone. The resultant compositions could take much more abuse than earlier molded resin compounds, and were made into everything from door knobs to billiard balls. 

The majority of the companies listed in Tables 1 and 2 store their available compounds in the form of dry powders (or whatever the natural state is), although samples dissolved in DMSO are becoming more available. For dry, solvent-free compounds selected from a supplier database, the samples will be weighed, usually manually, into cluster tubes or vials before shipping to the end user. This mode of operation may seem tedious, however, it does keep costs down for the preparation of samples for which automated weighing, e.g. of resinous compounds, is profoundly difficult. 

Epoxy resin compounds for treatment of technical textiles, especially glass fabrics and yarns. Excellent binding properties with bitumen and resins. 

A related aspect of cleaning-waste reduction is the minimization of clingage, which is material left inside equipment after draining. In operations involving viscous fluids, such as paint manufacturing and resin compounding, clingage is an important concern, since it is expensive to dispose of, and it represents a loss of product or raw material. 

Type 3—Packaging materials (resins, compounds, colorants, inks, components). 

The active constituents are resinous compounds called kava lactones. The exact mechanism of action is unclear though it is thought to act on GABA receptors resulting in the sedative effects. 

We have investigated the recovered glassfiber-resin powder for its properties as a filler for epoxy resin compounds which are used as paints or adhesives, and compared it to conventional fillers, such as talc and calcium carbonate. The epoxy resin compound, composed of bisphenol A type epoxy resin (50.0wt%), aliphatic polyamine type hardener (18.0wt%) and filler (32.0%), was prepared. Strength and thermal expansion properties were measured for the molded epoxy resin compound cured 23°C for 7 days. Viscosity was measured for the epoxy resin compound before adding the hardener. Adhesive strength was measured by tearing two ferric boards bonded with the epoxy resin compound which was composed of bisphenol A type epoxy resin (49.2wt%), polyaminoamide type hardener (18.0wt %), and filler (32.8wt%), and was cured at 23°C for 7 days.
