Is an oil in water emulsifier for petroleum oils, fats, waxes and alkyl esters. It is an excellent lubricant for metals, textiles, and leather, and is used as an emulsifier/ lubricant in soluble oils for metal processing and finishing. EMSORB 6903 also serves as a lubricant and highly efficient emulsifier for oils used in textile processing and finishing, glass fiber lubricants, and automotive lubricant additives. HLB 11.1...

Adhesion promoters were first used to treat glass fibers and other fdlers before they are incorporated into liquid resin to make composite materials. In the fiber industry, adhesion promoters are also known as finishes. Certain finishes have been specially developed to match a fiber with a resin matrix. Without adhesion promoters, the interfacial resin-glass fiber adhesion is weak, and water can diffuse along the interface with catastrophic results on the end properties of the composite. 

A wide variety of special durable surface treatments have been used on manufactured fibers. These include treatments for imparting such characteristics as soil resistance, antistatic behavior, and wearer comfort through moisture wicking and transport. Fiber finishes also have been used successfully in promoting adhesion between two materials, as, for example, between polyester tire cord and rubber, and between glass fiber and polyester resin. 

This moldable material primarily consists of TS polyester resin, glass fiber reinforcement, and filler. Additional ingredients, such as low-profile additives, cure initiators, thickeners, and mold-release agents are used to enhance the performance or processing of the material. As with any material, such as metallics and plastics, SMC can be formulated in-house or by compounders to meet performance requirements of a particular application such as tensile properties or Class A surface finish. Varying the type and percentage of the composition will result in variations in mechanical properties and processability. 

Low Temperature [-101 to -1°C (-150 to -l-30°F)] Cellular glass, glass fiber, polyurethane foam, and polystyrene foam are frequently used for this service range. A vapor-retarder finish with a perm rating less than 0.02 is required. In addition, it is good practice to coat all contact surfaces of the insulation with a vapor-retardant mastic to prevent moisture migration when the finish is damaged or is not properly maintained. Closed-cell insulation should not be relied... 

Another possibility is the use of the microlatices for assembling glass fibers since they have a low viscosity and good stability, as well as in the leather industry (finishing), in photographic emulsions and in paints. 

INTEX SIZE 51 is a highly specialized siloxane based finish for glass fiber to prepare the fabric for subsequent lamination. 

Determine the overall unit thermal resistance (the ff-value) and the overall heat transfer coefficient (the /-factor) of a wood frame wall that is built around 38 mm X 90-mm (2X4 nominal) wood studs with a center-to-center distance of 400 mm. The 90-mri-wide cavity betv een the studs is filled with glass fiber insulation. The inside is finished with 13-mm gypsum wallboard and the outside with 13 mm wood fiberboard and 13-mm x 200-mm wood bevel lapped siding, rtie insulated cavity constitutes 75 percent of the heat transmission area while the studs, plates, and sills constitute 21 percent. The headers constitute 4 percent of the area, and they can he treated as studs.

The single largest use for the phenol-formaldehyde resins is in adhesive applications for the production of plywood, chipboard, and particle board. The resin can comprise as much as one-third of the weight of the board, particularly of particle boards, which contributes to a total demand for phenolics in the U.S.A. of over half a million metric tonnes per year. They are also used as the matrix adhesives for the production of several types of grindstones. In combination with paper, woven cotton, glass fiber, etc., components, phenolics contribute to the production of engineering and decorative laminates in the form of rods, tubes, and sheets. The sheet products Arborite and Formica are familiar as the finished surfaces of furniture, bathroom, and kitchen counter tops and other areas where attractive patterns and water resistance are important characteristics. Molded products from phenolics are also important where heat or electrical resistance is required, such as saucepan and toaster handles, switches, and the printed circuit boards used in computers. Recent phenolics production in the U.S.A. has totaled over 500,000 metric tonnes per year, not including fillers [38]. 

Wet layup consists of placing a layer of dry reinforcement inside a mold and then applying an uncured, low-viscosity thermoset resin as shown in Fig. 2. Woven glass fibers are the prevalent reinforcing preform utilized in layup processes, although carbon and aramid fibers are also used to a lesser extent. Typical fiber volume fraction of composites manufactured via wet layup range between 30% and 50%. The resin can be poured, sprayed, or brushed on top of the preform layer either by hand or by machine. The fiber preform layer is rolled on or pressed after the application of resin to evenly distribute the resin and remove air pockets. Resin is applied on top after each layer of fiber mats is properly placed. This process is repeated until the desired thickness is reached. To provide a smooth surface finish on the mold side, a thin layer of mold release is often applied prior to starting the layup. Thereafter, pressure and heat are applied to allow the composite to cure. Pressure can be applied... 

Surface finish of parts is another important source of economic advantage. Surface roughness depends on the orientation of glass fiber. The process was optimized using data from surface smoothness measurements. A conductive RIM was developed to produce material ready for electrostatic painting without the need for further surface preparation.
