Limpet (Keasbey & Mattison)

Sprayed "Limpet" Asbestos was a sprayed-on coating sold in the United States by Keasbey & Mattison Company (K&M) of Ambler, Pennsylvania.1 In September 1936, Asbestos, the industry's trade journal, called sprayed insulation "the newest development in the insulation field" and said the material, "known as K & M Limpet Sprayed Asbestos," was "manufactured by Keasbey & Mattison Company, Ambler, Pa."1 The magazine's 1954 history of K&M said that "In 1936, K&M introduced Sprayed 'Limpet' Asbestos acoustical material . . . the first asbestos acoustical product in this country."2

The 1936 article said, "Because of its asbestos content, fire-resisting qualities are high."1 It could be sprayed on metal, wood, cement, brick or plaster, in pebbled or smooth finishes, natural or colored, and in hard, waterproof or sound-absorbing surfaces.1 On steel it was said to prevent corrosion by salt water.1 The same article reported it on the underdecks and bulkheads of the Gulf Refining Company tankers Gulf Belle and Gulf Dawn, and on the stack uptake and stack house of the Virginia Ferry Company's ferry boat Princess Anne.1 The 1954 history described it as an acoustical material "sprayed from a gun like paint," which could go on irregular surfaces and even be painted.2

In December 1958 the company announced Underwriters' Laboratories fire ratings for Sprayed "Limpet" Asbestos on cellular steel floors, beams and columns: four hours for floors and beams, and two, three and five hours for columns.3 In 1959 a new K&M folder, SL-8, said it "now offers protection from flames up to five hours depending upon the thickness of the blanket."4 A January 1961 folder gave sample specifications for ordering it "for fire protection, thermal insulation, noise reduction, or condensation control."5

K&M's ads from 1948 listed Sprayed "Limpet" Asbestos among the products it made.6 In 1956 the company had a sprayed "Limpet" asbestos department in its building materials division, and in January 1960 it appointed a merchandising manager for the product in its Building Products Division.7,8
