234 Reference BradyID.com Master Material Index Material Adhesion Comparison Material/Surface Adhesion Ratings Adhesion is the attraction between unlike materials. The strength of the adhesion is determined by the surface energy of the item being identified. The higher the surface energy, the greater the likelihood for the label to adhere. A lower surface energy product will be more difficult for a label to adhere. These following charts are based on relative adhesion after 24 hour dwell within each given surface energy category. SMOOTH SURFACE (High Surface Energy) Typical surface energy levels for this category are above 50 Dynes/cm. Surface Examples: Stainless Steel Tin Copper Glass Aluminum Smooth Metal Smooth Plastic TEXTURED/ROUGH SURFACE (Medium Surface Energy) Typical surface energy levels for this category are between 38-50 Dynes/cm. Surface Examples: Cast Metal Polyurethane Nylon ABS Alkyd Enamel Polycarbonate Polyester PVC Epoxy Paint Acrylic HIGHLY TEXTURED SURFACE (Low Surface Energy) Typical surface energy levels for low surface energy products are below 38 Dynes/cm. Surface Examples: Polystyrene Polypropylene Acetal Teflon Polyethylene Powder Coatings Highly Textured Highly Textured ABS HIGHLY TEXTURED SURFACE RATING Material Low High B-351 B-362 B-358 B-367 B-402 B-408 B-422 B-423 B-424 B-425 B-426 B-427 B-428 B-430 B-432 B-434 B-436 B-449 B-459 B-480 B-483 B-484 B-486 B-488 B-489 B-533 B-593 B-7546 B-7566 B-7576 B-8423 B-8425 TEXTURED/ROUGH SURFACE RATING Material Low High B-351 B-362 B-358 B-367 B-402 B-408 B-413 B-422 B-423 B-424 B-425 B-426 B-430 B-432 B-434 B-436 B-438 B-457 B-776 B-480 B-483 B-484 B-486 B-487 B-488 B-489 B-533 B-593 B-7546 B-7566 B-7576 B-8423 B-8425 SMOOTH SURFACE RATING Material Low High B-103 B-330 B-351 B-362 B-358 B-367 B-402 B-413 B-422 B-423 B-424 B-425 B-426 B-427 B-428 B-430 B-432 B-434 B-435 B-438 B-439 B-449 B-457 B-459 B-464 B-473 B-776 B-480 B-483 B-484 B-486 B-487 B-488 B-489 B-499 B-533 B-593 B-717 B-718 B-719 B-7546 B-7566 B-7576 B-8423 B-8425 B-966B Please see Brady Technical Data Sheets at BradyID.com/techdata for specific adhesion values. Testing in the specific application is recommended.
