High-performance 2 mil acrylic adhesive transfer tape with exceptional temperature resistance up to 450°F, excellent chemical resistance, and superior shear strength for bonding high and low surface energy materials.
3M™ Adhesive Transfer Tape 9442 is a high-performance transfer tape consisting of 3M™ Adhesive 350, a modified high-performance acrylic adhesive designed for applications requiring high shear strength and temperature resistance. This 2.0 mils (.05 mm) thick tape is mounted on a white, 55 lb. densified kraft paper liner for general purpose applications. The tape provides excellent bonding to both high and low surface energy materials, including powder coated paints, making it an ideal solution for diverse industrial bonding applications.
The adhesive formulation features exceptional chemical resistance and maintains superior shear and peel strength even at elevated temperatures. With a fiber-reinforced adhesive design, this tape offers excellent roll stability in narrow widths and resists oozing during application. The tape is engineered for short-term temperature exposure up to 450°F (232°C) and long-term performance at 300°F (149°C), making it suitable for demanding industrial environments. Its low odor formulation ensures an improved working environment for operators.
This transfer tape is specifically designed for industrial and occupational use, offering reliable performance in bonding applications across multiple industries including automotive, electronics, appliances, metalworking, medical devices, and specialty vehicles. The solvent-free composition provides excellent resistance to gasoline, oil, sodium chloride, mild acids, alkaloids, moisture, and humidity, making it a versatile choice for challenging bonding requirements.
