Its highly conformable white glass cloth backing offers high edge-tear resistance plus excellent puncture, abrasion, and solvent resistance, blending cleanly into finished aerospace work. The trusted choice for permanent cargo-compartment sealing, it bonds securely over difficult textures and uneven or curved surfaces, and is also available in a printed version (398FRP).\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0741\/9910\/5734\/files\/3M-398FR_TDS_SkyTapes.pdf?v=1782740524\" target=\"_blank\" title=\"3M Glass Cloth Tape 398FR TDS\" rel=\"noopener\"\u003e\u003cspan style=\"color: rgb(43, 0, 255);\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003e3M 398FR TDS\u003c\/strong\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/a\u003e\u003ca href=\"#\" title=\"3M Glass Cloth Tape 398FR TDS\" rel=\"noopener\" target=\"_blank\"\u003e\u003cspan style=\"color: rgb(43, 0, 255);\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eDesigned for insulating, bundling, splicing, holding, and sealing applications, its long-aging acrylic adhesive provides high, secure adhesion for extended periods across a wide range of climate and temperature conditions.
