Scrim glass fabric

PVC plastisols and latexes are involved in the production of many useful products, including protection of scrim glass fabric used for reinforcement of cementitious boards and other products, production of breathable fabrics woven from coated fibers, fiber optics, and production of various articles (e g., fishing lines or tennis racket string) from coated fibers. Some examples are given below. 

In reinforced plastics the fabrics most commonly used are glass, cotton, nylon, polyethylene, and aramid. Glass fabrics are used in electrical-grade laminates, mechanical laminates, and marine-grade laminates. Scrim glass fabrics are used as facing layers for smooth, cosmetic applications. 

The adhesive is manufactured in tape form by a hot-melt process. It is a tacky solid at room temperature. The integrity is maintained by using a finely woven glass fabric scrim as the carrier. This process is an excellent example of the compromises required in the technology of formulation. Some of the high-temperature performance that is expected from the phenolic resole is sacrificed for the improved bond strength and toughness afforded from the epoxy resin. The filler is added to make the thermal coefficient of expansion of the cured adhesive more metallic in nature. Dicyandiamide is the... 

Non-woven scrim An open-mesh glass fabric in which two or more layers of parallel yarns are bonded to each other by chemical or mechanical means, the yarns in adjacent layers lying at an angle to each other. 

Because the host pipe was made of steel, to avoid galvanic corrosion the pipe first had to he lined with a glass fabric. This was satisfied by including very thin glass scrims on both faces of the FRP laminate. 

As with tissue, woven glass cloth is used for decorative or acoustic purposes. Additionally, close-woven fabrics give improved fire-safety properties and are resistant to mechanical abuse. Glass cloth or scrim of an extremely open weave is used on insulants as a key for mastic or hard-setting finishes. 

Tape and film are the most common forms of solid epoxy adhesives. Tape and film are terms that are used rather loosely for adhesives in a thin sheet form. The term tape generally refers to an adhesive that is supported on a web of paper or nonwoven fabric, or on an open-weave scrim of glass, cotton, or nylon. Films, on the other hand, are free of supporting material and consist only of the adhesive. Both tape and film products may be accompanied with a release liner depending on the tack or blocking characteristics of the adhesive.

Glass is available in the form of rovings (untwisted bundles of strands), yam (twisted bundles of strands), and bonded, needled, woven and knitted fabrics made fi om each. Yam-based fabrics are the most expensive but yield the strongest composites. The cheapest fabric is the chemically bound, non-woven, two-dimensionally random, chopped strand mat, but where better mechanical properties are needed tapes, scrims, square weaves, twills, satins and various knitted constructions are preferred.
