Speedlag (Raybestos-Manhattan)

Speedlag was an adhesive-impregnated asbestos lagging cloth made by Raybestos-Manhattan's Asbestos Textile Division for thermal insulation work.1 In a 1968 ad in Asbestos, the industry's trade journal, R/M offered four Speedlag cloths: 18P075, napped and calendered; 10P111 and 10P140, made of Glassbestos, a glass-yarn-reinforced asbestos cloth; and 10P225, a standard weight asbestos cloth, in widths from 36 to 60 inches, with slit tapes also available.1

The ads describe the adhesive differently. The 1968 ad spoke of a combination of two adhesives that also served as fillers, so the cloth needed no sizing before painting.1 A 1970 ad said the cloth was cut and fitted, dipped in water to activate its "100% inorganic adhesive," and put in place.2 That ad offered Speedlag in two ASTM grades: Underwriters Grade, made to a federal specification, and AAA Grade, for insulation on merchant vessels covered by U.S. Coast Guard specifications.2

Who bought it

In R/M's own sales and price records, a February 1969 price card for Porter Hayden of Baltimore lists rolls of 10P140 Glassbestos cloth, "Speedlag Treated," and a later card lists the glass-yarn-reinforced 10P111 as "type speedlag."3 In July 1971 R/M quoted the glass-yarn-reinforced 10P111, type Speedlag, among other cloths for the annual asbestos cloth needs of Maryland Shipbuilding and Drydock Company.3 A 1970 card lists 18P075 as a woven asbestos cloth "speedlag treated," and a price schedule for "Speedlag Asbestos Cloth" dated December 3, 1973 was offered to a customer for its 1974 needs.3

An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, gives Speedlag as a cloth made from 1969 to 1976 and puts its asbestos content at 65%.4
