OMG - OlyBond500® 15 Gallon Adhesive Drums

OB500-15A and OB500-15B are the two drum components of OMG’s OlyBond500 roof insulation adhesive. The Part 1 drum (OB500-15A) contains one half of the system, while the Part 2 drum (OB500-15B) completes the system when mixed. When applied, the adhesive rises quickly, curing in 4 to 8 minutes depending on weather, to secure insulation board to deck or cover board in new construction or re-roofing applications.

Key Features

• two-component polyurethane adhesive system (Part 1 & Part 2)
• fast tack time (curing in 4 to 8 minutes depending on ambient conditions)
• low odor formulation, suitable for sensitive areas
• compatible with a wide range of roof decks, substrates, and insulation board types
• available in regular and winter formulations

• OB500-15A (Part 1, 15 gallon drum)
• OB500-15B (Part 2, 15 gallon drum)

Drum Weights:
• OB500-15A (15 gal): approximately 160 lbs
• OB500-15B (15 gal): approximately 135 lbs

Application & Physical Properties:
• curing time: approximately 4 to 8 minutes depending on temperature and weather conditions
• adhesive rise above substrate: adhesive beads rise approximately ¾ to 1 inch above substrate after application
• bead width / spacing: applied in ¾ to 1 inch beads, spaced per manufacturer’s recommendations (commonly up to 12 in on center)

Approvals & Use Conditions:
• low odor, low VOC adhesive suitable for sensitive buildings such as hospitals and schools
• compatible with many roof decks, substrates, and cover boards
• available in regular and winter grade formulas for different ambient temperature ranges

• Ensure surfaces (roof deck or insulation board) are clean, dry, and free of debris or grease
• Set up drums OB500-15A and OB500-15B, ensuring you have the correct formulation (regular or winter) for ambient temperature
• Dispense Part 1 and Part 2 simultaneously through the dispensing system, maintaining a 1:1 ratio
• Apply adhesive in beads that are ¾ to 1 inch wide, spaced per manufacturer’s guidelines (often up to 12 inches on center)
• Lay insulation board into place, walking into bead lines to ensure full contact
• Allow adhesive to cure (typically 4 to 8 minutes depending on temperature)
