FOSTER LAGFAS ® ADHESIVE/COATING

FOSTER LAGFAS Adhesive/Coating is a waterbased polyvinyl acetate emulsion adhesive with typical quick-setting properties, used extensively for adhering and sizing canvas and glass cloths, and other types of fabric covering over thermal insulation installed indoors. It presents a neat white cleanable finish, and will not yellow or become discolored with age. Cotton fabrics shrink tight and smooth onto the insulation.

LAGFAS Adhesive/Coating has excellent brushing characteristics, which will result in better coverage and uniformly coated surfaces.

LAGFAS Adhesive/Coating complies with current requirements regarding use in meat and poultry processing areas under federal inspection. Letter of certification is available upon request.

LAGFAS Adhesive/Coating contains no asbestos, lead, mercury, or mercury compounds.

LAGFAS Adhesive/Coating meets requirements for LEED IEQ 4.1 Low-Emitting Materials, Adhesives and Sealants when used as a lagging adhesive. VOC: 55 g/l, less water and exempt solvents ­ theoretical (<10g/l analytically determined).

LAGFAS Adhesive/Coating is produced under the classification and follow- up service of Underwriter's Laboratories, Inc. and meets NFPA 90A & 90B 25/50 requirements.

LIMITATIONS
Store and apply between 40ºF (4ºC) and 100ºF (38ºC), protect from freezing until dry. Always test foil and paper facings for acceptable adhesion before using.
