DUOTACK® 365 is a low rise, two component polyurethane adhesive. DUOTACK 365 is used to adhere insulation and cover boards to approved substrates. Insulation and cover boards include polyisocyanurate, polystyrene, mineral fiber, gypsum, wood fiber, cement, perlite and asphaltic roof boards. DUOTACK 365’s unique chemistry provides for a versatile quick setting adhesive that is not susceptible to low relative humidity or temperature.
DUOTACK 365 is applied to approved substrates free of oil, grease, dirt and other contaminants in ½” to ¾” ribbons. Maximum spacing for these ribbons is 12 inches on-center, though 6 inches and 4 inches on center are used in perimeters and corners. Once applied, immediately place the insulation/coverboard into the wet adhesive and do not allow the adhesive time to skin over. Maintain constant pressure/weight on the boards while DUOTACK 365 cures, usually in minutes but may vary depending on environmental conditions.
