Soundown’s ATA-30 Adhesive and Grout is a two component, high tack strength, epoxy adhesive specifically developed for the installation of vibration damping materials such as MLD-2 Tiles, RA, Saper, Isoper, PVC and other. Clamping or shoring is generally eliminated as ATA-30 Adhesive will support in excess of 25 kg/sq.m. (5 lbs./sq.ft.) on overhead and vertical surfaces while curing takes place. ATA-30 is excellent for grouting between damping tile sheets and for forming fillets at welds or seams. ATA-30 is nontoxic and contains no solvents. Fumes and odors of mixed ATA-30 are negligible thus facilitating usage in confined areas. Resistance to fresh water, salt water, crude and refined oils, gasoline, jet fuel, etc., is excellent.

MIXING:

ATA-30 is mixed one part white resin to one part black hardener by volume. Equal sized quantities are best placed side by side on a wood or hard soard surface and thoroughly mixed until a uniform gray color is achieved. Mix quanties, which can be used within approximately one hour. ATA-30 has an exceptionally soft creamy consistency providing ease of mixing.

APPLICATION:

Mixed adhesive may be applied to damping tile or sheet with either a smooth or notched trowel. With smooth edge trowel apply uniformly at approximately 0.8mm (1/32") or thicker. Notched trowels with serrated edges of 1.6mm (1/16") or larger may be utilized. Coat entire surface of tile evenly including edges. Bend coated tile and starting with edge roll onto hull structure such that adhesive spreads under tile ensuring that air is not entrapped. Adhesive may be applied to either or both surfaces. Intimate contact may be further insured through pounding with a rubber mallet.

ATA-30 develops excellent bond between poorly fitted surfaces and is recommended for metals, rubber, wood, glass, masonry and many plastics.

CLEAN-UP:

ATA-30 is easily cleaned off tools and hands prior to setting with water.
