When choosing masking tape, three core parameters need to be considered: operating temperature, tack rating, and substrate thickness. Operating temperature determines whether the tape can be used in high-temperature environments (e.g., 120℃ models are suitable for painted surfaces); the tack rating must match the material of the surface to be adhered to (e.g., high-tack models are needed for smooth metal surfaces, while reinforced-tack models are needed for rough walls); substrate thickness affects tear resistance and flexibility (thicker tapes are suitable for curved surfaces, while thinner tapes are easier for precise application). Furthermore, tapes that meet national or manufacturer standards have undergone rigorous testing of their adhesive layer thickness, peel strength, and other indicators, resulting in a better balance between tack and tearability.
When using masking tape, pay attention to environmental cleanliness-dust and oil will reduce adhesion; it is recommended to clean the surface before application. When peeling, control the angle and speed; tearing vertically and quickly reduces the risk of adhesive layer breakage. For long-term storage, avoid high-temperature and high-humidity environments to prevent adhesive layer aging.
