Butyl Adhesive Sealant Tapes
Butyl tapes are thick, permanently tacky elastic products that stick to most substrates and seal out moisture and liquids. Often used for seaming in construction they will not stain, are resistant to fungus and mildew growth and bond well to oily metals and recycled styrene butadiene rubber derived from recycled tires. While the cohesive strength is low, its tacky nature, thickness, and moisture resistance quality make butyl tapes ideal as an easy to apply sealant.
Applications include: Standing roof seams for metal building roofing skylights, vents etc. Rivet seams and lap seams in truck trailers and RVs. Cabinet sealing in HVAC and appliance production.
- Bonds to most substrates without primer
- Non-curing
