Description
feature
Our mastic tape can be used on copper or aluminum conductors rated at 95℃, with an emergency overload rating of 130℃. It offers excellent resistance to moisture and ultraviolet exposure and is intended for both indoor and weather exposed outdoor application.
Excellent waterproofing – Forms a tight, moisture-proof barrier
Highly adhesive and conformable – Sticks firmly to various surfaces including metal, plastic, and rubber
Corrosion and chemical resistant – Protects metal parts from rust and degradation
Non-hardening and flexible – Remains soft and pliable over time, allowing movement without cracking
Cold-applied – Easy to use without heating or special tools
Self-fusing and non-curing – Creates permanent seals without drying out or shrinking

FAQ
Q1: Can waterseal mastic tape be used underwater?
A: While it provides excellent waterproofing, it is typically used in damp or wet environments rather than fully submerged conditions unless specified by the manufacturer.
Q2: How long does the seal last?
A: With proper application, the tape maintains its sealing properties for many years, resisting weathering, UV, and temperature fluctuations.
Q3: Is it reusable?
A: No. Once applied, the tape forms a permanent seal and should not be removed and reapplied.
Q4: Does it require heating or curing?
A: No. Waterseal mastic tape is cold-applied and self-fusing, meaning no heat or drying time is necessary.
Q5: Can it be painted over?
A: Some mastic tapes can be painted; however, it depends on the tape's formulation. Check with the manufacturer for specific compatibility.
