Review the archived 2010 Bayfol UV1 7-2 sheet with context on textures, gauges, typical properties, printing, forming, and assembly validation. This resource is for manufacturers evaluating custom nameplates, labels, overlays, or related identification components. Use it to prepare your project questions, then talk with our team about the requirements that apply to your part.
Bayfol Polycarbonate UV1 7-2 is represented in U.S. Nameplate’s archive by a one-page Curbell Plastics supplier sheet published in 2010. The sheet calls UV1 7-2 an ultraviolet-resistant polycarbonate film with a first-surface velvet texture and a second-surface fine-matte texture. It provides typical physical, optical, mechanical, ultraviolet, and chemical-test values. Because the document is dated and issued by a supplier, confirm the current manufacturer, grade designation, availability, and specification before selecting it for any overlay, panel, label, or nameplate.
The archived overview identifies two different textures: velvet on the first surface and fine matte on the second. Surface orientation can affect appearance, print placement, tactile feel, and how the film is shown on a drawing. A project should define which side faces the user, which side receives graphics or adhesive, and how that orientation will be verified during production.
For a Graphic Overlay or Control Panel Overlay, the stack may include printed colors, windows, selective texture, adhesive, liners, and cut features. The base-film name alone does not communicate that construction. Supply a section view or layer schedule when orientation is important.
The 2010 Curbell sheet says Bayfol UV1 7-2 was available in 0.007, 0.010, 0.015, 0.020, 0.025, and 0.030 inch thicknesses. The local file name, PCUV1.010, suggests the 0.010-inch version, while the page title refers to the broader grade. Do not infer that every historical gauge remains available or interchangeable.
Thickness influences stiffness, formed-feature behavior, embossing, cutting, window appearance, edge profile, and the feel of a control surface. If a customer is replacing an existing overlay, measure the full assembly and identify whether thickness is nominal, minimum, maximum, or reference. Confirm current tolerance information from the manufacturer rather than treating the old list as a dimensional specification.
The one-page sheet reports values under named ASTM methods for specific gravity, water absorption, gloss, haze, light transmission, yellowness, tensile strength, elongation, and tear initiation. It also reports yellowness-index observations after several xenon-arc durations under SAE J1960. These values are useful for comparing questions, but the supplier cautions that it cannot guarantee completeness or accuracy and assigns application suitability to the customer.
The archived Curbell sheet lists one-hour surface-contact tests at 73 degrees Fahrenheit for 40-percent sodium hydroxide, concentrated hydrochloric acid, and premium gasoline, with each shown as passed. Its footnote defines failure as permanent staining, blistering, delamination, or cracking. That does not establish compatibility with different concentrations, temperatures, contact times, cleaners, mixtures, vapors, repeated cycles, or the printed ink and adhesive in a finished component.
Prepare a chemical list for the real application. Include product names or concentrations, contact method, duration, rinse, temperature, frequency, and what appearance or function must be retained. Test the whole converted stack, especially printed surfaces, clear windows, adhesive edges, and formed features.
Polycarbonate overlays are often discussed in terms of first-surface and second-surface graphics, but the correct orientation depends on the film, texture, desired appearance, and exposure. Printing on the reverse side may place the film between users and the graphic; printing on the exposed face may be required for another effect. Neither approach should be assumed from the grade name.
U.S. Nameplate’s Screen Printing and Digital Printing capabilities provide context for image creation. Ink adhesion, opacity, registration, cure, color, window clarity, and resistance must be verified with the current film. A material supplier’s base-film table does not qualify a particular print system.
Finished overlays may require perimeter cuts, holes, windows, key openings, embossed areas, or formed features. Die & Digital Cutting can support controlled geometry, while Embossing & Forming provides a related manufacturing context. The achievable geometry depends on thickness, feature spacing, tooling, print placement, and customer tolerances.
A representative sample should include the tightest radii, narrowest webs, critical windows, and any formed areas. Evaluate cracking, whitening, distortion, registration, feel, and fit. Do not use the archived tensile or elongation number as a substitute for testing the actual feature.
The Curbell sheet describes the polycarbonate film, not a complete adhesive-backed overlay. If the part mounts with pressure-sensitive adhesive, define the adhesive product or required performance, coverage pattern, thickness, liner, pull tab, and excluded zones. Windows, vents, buttons, grounding areas, and service openings may require precise adhesive cutouts.
3M Adhesives provides a product category for attachment discussions, and Laminating describes a manufacturing step. Those links do not recommend a specific adhesive for UV1 7-2. Compatibility, surface preparation, and bond validation must be confirmed for the equipment surface and service conditions.
The archived sheet names gas-pump graphics, harsh environments, nameplates or labels, and outdoor signage as applications. These are supplier examples. They do not prove that U.S. Nameplate has produced a particular item from this grade, that the film complies with a fuel-dispenser standard, or that it will withstand every outdoor or industrial environment.
Use the example closest to the project only to identify further questions. A gas-pump graphic, for instance, may involve fuels, cleaners, sunlight, user contact, regulatory artwork, and specific substrate geometry. Each condition needs current documentation and an assembly-level approval plan.
Begin by requesting the latest Bayfol UV1 7-2 technical bulletin and confirming that the grade name, supplier chain, textures, gauges, and typical values are still current. Define the layer order, print system, colors, windows, adhesive, liner, geometry, quantity, packaging, and inspection criteria. Produce a sample from current production-intent materials and test the features and exposures that matter.
Submit the controlled drawing and application details through Request Consultation. U.S. Nameplate can review printing and fabrication requirements for the identification component. Current supplier confirmation, customer engineering approval, regulatory review, and final suitability testing remain outside what this dated resource page can establish.
For reorders, preserve the approved sample and layer schedule with the revision record. If the film supplier changes a code, gauge, texture, or technical bulletin, route that change back through the same visual, dimensional, functional, and environmental review. This keeps a legacy material name from silently becoming an uncontrolled substitution.
