Automotive sealing tape is a crucial sealing material used in modern automotive engine repair, primarily addressing the "three leaks" (leakage, leakage, and cracking) issues in engines.
Its classification is mainly based on its matrix and function: PVC-based sealants can be divided into colorable and non-colorable types, mainly used to isolate moisture, dust, and smoke, provide corrosion protection, sound insulation, and enhance appearance; polyurethane sealants ensure tight connections between various parts of the vehicle, preventing liquid or gas leaks, and are commonly used in areas such as windows, doors, and engine compartments. Colorable PVC sealants can be used for areas requiring aesthetic enhancement, while non-colorable types are suitable for situations where color is not a primary concern; polyurethane sealants, due to their performance characteristics, are frequently used in engine repair and similar applications.
