ASLONG Butyl Waterproof Tape — Durable Seal for Soundproofing & Weatherproofing

ASLONG Butyl Waterproof Tape is a high-performance butyl rubber tape designed to form a durable, flexible seal that blocks air, moisture, and vibration. As a sealing layer it complements traditional soundproofing materials—such as butyl rubber sound damping mats and mass loaded vinyl—by eliminating small gaps and flanking paths where sound and water can penetrate. Manufactured by ASLONG (Welllink Guangdong New Material Co., Ltd.), a high‑tech enterprise founded in 2000 with over 10,000 m² of modern production capacity, our butyl waterproof tape delivers long-term adhesion and acoustic sealing for construction, automotive, residential, and industrial applications.

Yes. ASLONG butyl waterproof tape is formulated for demanding environments and is commonly used outdoors and in vehicle applications for weatherproofing and vibration isolation. The tape’s elastomeric butyl compound remains flexible to maintain a watertight seal under thermal expansion and contraction. For best outdoor performance we recommend proper surface preparation and correct application (see installation tips). ASLONG products have been exported worldwide and are designed to meet the durability expectations of construction, automotive, and industrial customers.

For reliable performance, clean and dry the substrate to remove dust, grease, and loose paint. Cut the tape to length, peel back the release liner, and press the tape firmly onto the surface—use a roller for consistent pressure and full contact. Overlap seams by 5–10 mm where possible and apply continuous strips across joints, gaps, and flange areas to block airborne and structure-borne sound paths. For improved acoustic performance combine our butyl waterproof tape with ASLONG sound damping mats, mass loaded vinyl, or NBR foam. If working in cold conditions, warm the tape slightly to improve tack before application.

ASLONG butyl waterproof tape is engineered for strong, long-lasting adhesion. On most durable, non‑porous surfaces it will perform without causing corrosion. However, like most high‑tack sealants, leaving the tape in place for extended periods—especially on delicate paints or finishes—can make removal more difficult and may leave residue. We advise performing a small test patch on sensitive surfaces before large‑scale application. If residue occurs, it can usually be removed carefully with heat and appropriate solvents; contact ASLONG technical support for recommended solvents and removal procedures.

ASLONG supplies butyl waterproof tape to customers worldwide and supports sample requests, bulk orders, and distribution partnerships. Our product range serves construction, automotive, residential, industrial, and entertainment sectors, and we export to Europe, North America, Asia, Africa, and beyond. We are also recruiting agents globally. For pricing, lead times, samples, or to discuss a partnership, please contact our sales team at king@aslong.cc or visit our website https://www.aslong.cc. As a reminder, ASLONG (Welllink Guangdong New Material Co., Ltd.) has been specializing in acoustic and sound insulation materials since 2000 and can provide technical guidance to help you select the right butyl waterproof tape solution for your project.
