It features a low surface energy (LSE) acrylic adhesive bonded to the back of a clear polypropylene mushroom-stem strip. The engaged thickness when two mating strips are closed is 0.10 inches, producing a low-profile assembly that works well in tight tolerances. Rated for up to 100 closure cycles, this fastener is engineered for indoor applications requiring a reliable, tool-free mechanical bond. Temperature resistance reaches 158 degrees F, making it suitable for low to medium temperature environments. The roll weighs 12 pounds and ships as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in interior panel attachment, cable management, signage mounting, and light-duty component securing across commercial and industrial settings. It adheres directly to metals such as aluminum and stainless steel, glass, and a wide range of plastics including polypropylene, polyethylene, polycarbonate, and ABS. It also bonds to powder-coated paint surfaces and other medium to low surface energy substrates. It is not intended for outdoor exposure, high-temperature environments above 158 degrees F, or very high surface energy materials where a PSA-only bond would be insufficient.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLow profile design with 0.10 inch engaged thickness for space-constrained installations\u003c\/li\u003e\n  \u003cli\u003eRated for 100 open-and-close cycles, providing long service life in repeated-access applications\u003c\/li\u003e\n  \u003cli\u003eLow surface energy acrylic adhesive bonds to LSE plastics, metals, glass, and powder-coated surfaces\u003c\/li\u003e\n  \u003cli\u003eClear polypropylene construction keeps fastener visually unobtrusive on transparent or finished surfaces\u003c\/li\u003e\n  \u003cli\u003eTemperature resistance to 158 degrees F for low to medium thermal environments\u003c\/li\u003e\n  \u003cli\u003eContinuous 6 inch wide by 50 yard roll allows field cutting to any required length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for bonding to metals (aluminum, stainless steel), glass, polypropylene, polyethylene, polycarbonate, ABS plastics, powder-coated paints, and medium to low surface energy materials.
