Applications

CONTEGA HF^® is a dependable, durable, and flexible air-tight adhesive for connections between interior or exterior air barriers and/or uneven substrates. It can be used on the interior or exterior of the building.

Coverage in linear ft. will depend on the width of the bead applied and the roughness of the substrate.

Advantages

• Exceptionally high adhesion properties while also remaining elastic
• PHI Class A Certified Airsealing Component
• Long-term elasticity combined with high strength and resistance to tension
• No permanent clamping is needed in most cases
• Sets in 48 hours to full strength

Substrates

• Bonds all Pro Clima membranes and PP-,PE, PA-, and Aluminum foils to substrates (wood, brick, concrete)
• Works in conjunction with ProClima membranes, TESCON VANA, CONTEGA TAPES etc to connect solid or angled connections between different airtight construction materials
• On the exterior, connects weather resistant barriers, sub roof membranes, under rain screen membranes and wind/watertight construction components

Properties

• Material: Dispersion based on acrylic acid copolymers and ethanol, free of surfactants and halogens
• Application Temperature: 14 °F to 122 °F (-10 °C to 50 °C) [No adhesion to frozen objects]
• Can be stored below freezing thanks to minized ethanol (alcohol) content
• Works on slightly damp substrates, water resistant connection
  
• Good for uneven and porous substrates as it forms to, and penetrates into the substrate
• NBC 2020- 9.36.2.9  Air Barrier Systems Passed air leakage <0.02 L/(s·m²) @75 Pa (ASTM E2357)
  
• Low VOC per SCAQMD limits
• LEEDV4 passed CDPH v1.2 for Private Office and School Classroom (PO and SC)
