H.B. Fuller has "stuck to its knitting," which ironically is glue, for more than a century. Long known for making adhesives, sealants, and specialty chemicals, the company markets its products in some 40 countries. Industrial adhesives are its core product offering, and customers include companies in the assembly, packaging, automotive, woodworking, and nonwoven textiles industries. Other products include construction materials, principally ceramic tile installation products (such as grouts, mortars, and sealers) and HVAC insulating coatings (duct sealants, fungicidal coatings, and weather barriers).
