Matte and velvet finishes
Best for controlling glare, reducing visible fingerprints, and creating a low-sheen tactile surface.
[ Overview ]
What Are Finishes And Coatings?
Control how an interface looks, feels, reflects light, resists wear, and supports everyday use..
Finishes and coatings are surface characteristics or applied layers that change how a product looks, feels, and performs at the point of interaction. A finish may be inherent to a film or molded material, created through a texture, or applied selectively. A coating is an added surface layer used to create a specific visual, tactile, optical, or protective function.
Within ALMAX Keypads & Interfaces, Finishes And Coatings belong to the Aesthetics group because they shape the visible and tactile surface experience. They can also support functional goals such as controlling glare, improving cleanability, protecting printed graphics, reducing visible fingerprints, or increasing resistance to abrasion and selected chemicals.
They are not a complete keypad or interface assembly by themselves. They are product-specific surface treatments integrated with the material, graphics, windows, keys, enclosure, and manufacturing process.
Control how an interface looks, feels, reflects light, resists wear, and supports everyday use.
This page focuses on Finishes And Coatings as engineered surface treatments that tune appearance, tactility, optical behavior, and protection; related products and technologies are mentioned only where they help explain construction choices, integration, alternatives, or system fit.
[ System Fit ]
Where They Fit in the Product System
Finishes and coatings sit at or near the user-facing surface of the product. Depending on the construction, they may be:
The assembly commonly interfaces with
- Built into the exposed surface of a polyester or polycarbonate film
- Applied over printed graphics, a key field, or a molded component
- Used selectively around buttons, grip zones, branding, or high-wear areas
- Specified over a display or indicator window for optical and cleaning requirements
- Applied to silicone rubber, rigid plastic, a cover lens, label, or nameplate
- Coordinated with an adhesive-backed overlay, membrane switch, capacitive interface, or smart keypad
The finish must work with the complete stack. Surface texture can affect readability and light diffusion; coating thickness and flexibility can affect forming and lamination; and the selected chemistry must be compatible with the substrate, inks, adhesives, cleaning agents, and production process.
[ How It Works ]
How Finishes And Coatings Work
The user sees, touches, cleans, or wears the front surface during normal use. The finish changes how that surface reflects light and feels under the finger, while a functional coating can add a controlled barrier or surface property.
For example, a matte texture scatters reflected light to reduce glare; a gloss area produces a smoother, more reflective appearance; a hard coat helps the surface resist scratching or abrasion; and an anti-smudge treatment can reduce the visibility of fingerprints.
Optical coatings or carefully selected surface textures can be used around windows to support readability.
The result is a surface engineered for the intended product experience rather than a generic cosmetic layer. Actual performance depends on the substrate, coating system, cure, geometry, exposure, and validation method.
[ Variations ]
Common Types and Variations
Satin finishes
Used when the product needs a balance between a soft visual appearance and easier cleaning.
Gloss and high-gloss finishes
Used for strong color depth, a smooth premium appearance, or clear window areas.
Selective or spot finishes
Best for combining effects, such as gloss keys on a matte field or a clear window within a textured panel.
Hard coats
Used when additional abrasion, scratch, or chemical resistance is required and verified for the application.
Anti-glare or anti-reflective options
Used around displays and viewing areas to manage reflections under defined lighting conditions.
Anti-fingerprint or smudge-resistant coatings
Used on frequently touched, smooth surfaces where appearance and cleanability matter.
Soft-touch coatings
Used when a warmer, higher-friction, or rubber-like feel is desired on a compatible substrate.
Antimicrobial additives or coatings
Considered for applications with a defined hygiene requirement; the exact additive, claims, regulations, and validation must be specified for the intended market.
Hybrid constructions
Used when different zones require different properties, such as a durable key field, a clear optical window, and a branded decorative area on one interface.
[ Applications ]
Typical Applications
- Industrial control panels exposed to frequent handling and cleaning
- Medical and laboratory equipment with defined disinfectant and wipe-down routines
- Outdoor controls requiring attention to glare, UV exposure, moisture, and abrasion
- Appliances and consumer devices where color, gloss, texture, and fingerprint visibility affect perceived quality
- Transportation and mobility interfaces with high-touch controls and changing light conditions
- Display and indicator windows requiring a separate optical finish from the surrounding field
- Membrane switches and custom keypads with printed legends and repeated key actuation
- Rubber keypads requiring a specified tactile feel, appearance, or protective surface treatment
- Labels and nameplates exposed to handling, cleaning, weather, or chemicals
The correct surface solution is driven by the real use environment rather than the industry label alone.

[ Benefits ]
Customer Benefits
Stronger product identity
Gloss, matte, texture, and tactile contrast can reinforce the visual and physical character of the brand.
Improved usability
Surface cues can help users identify controls, grip the product, or distinguish functional zones.
Better readability
Glare-control strategies and separately specified window finishes can support viewing under the intended lighting conditions.
Longer-lasting appearance
A compatible protective treatment can help printed or molded surfaces withstand the defined wear and cleaning profile.
Fewer integration surprises
Coordinating the finish with the substrate, graphics, forming, lamination, optics, and enclosure reduces the risk of treating the surface as a late cosmetic decision.
Efficient assembly
Selective finishes can create multiple surface effects on one component without adding separate decorative parts.
Custom design flexibility
Different areas can be tuned for appearance, touch, wear, or optical function within the same interface.
[ Materials & Construction ]
Materials, Construction,
and Technology Options
Common substrate and surface platforms include
- Textured or clear polyester films
- Polycarbonate films with selected gloss and texture levels
- Molded plastic surfaces with tool-defined texture
- Silicone rubber key surfaces
- Acrylic, polycarbonate, or glass cover lenses
- Printed graphic overlays and labels
- In-mold decorated or formed surfaces
A finish may come from the base material, a molded tool texture, a printed texture, a lacquer, or another applied coating system. Selective application can create contrasting zones without changing the underlying component.

[ Performance ]
Performance and
Durability Factors
Long-term behavior depends on the combination of substrate, coating, surface preparation, cure, geometry, handling, environment, and maintenance. A finish that performs well on a flat film may behave differently after embossing, forming, or molding.
Depending on the design, materials and coatings can be selected for resistance to abrasion, scratches, selected chemicals, repeated cleaning, UV exposure, moisture, and temperature. These properties should be verified against project-specific requirements.
ASTM F1842 provides a method for evaluating ink or coating adhesion on flexible substrates. ASTM F2357 and ASTM F3152 describe comparative abrasion methods for inks and coatings, including dry and, for F3152, wet chemical conditions. Test results depend on the stated equipment, media, force, conditioning, and specimen geometry; they should not be converted directly into a guaranteed number of finger touches or years of service.

FAQ’s
Your questions, answered.
What are finishes and coatings used for?
They are used to control a surface’s appearance, tactile feel, glare, cleanability, optical behavior, and resistance to defined wear or environmental conditions.
What is the difference between a finish and a coating?
A finish describes the resulting surface appearance or texture and may be inherent to the base material or molding process. A coating is an added layer used to create or improve a specific surface property. In practice, the terms can overlap, so the construction should be specified rather than relying on the name alone.
What is the difference between Finishes And Coatings and Graphic Overlays?
A graphic overlay is a printed user-facing component that carries legends, colors, windows, and interface information. Finishes and coatings are surface treatments that may be applied to or built into that overlay—or used on silicone, molded plastic, lenses, and other parts.
Can different finishes be combined on one surface?
Yes. Selective or spot finishing can combine matte, gloss, texture, clear windows, grip zones, or protected wear areas, subject to material and process compatibility.
Can a coating make a surface chemical-proof or scratch-proof?
No generic coating should be described that way. A suitable system may improve resistance, but performance depends on the chemical, concentration, exposure time, wiping method, substrate, cure, and acceptance criteria. The actual construction should be tested against the customer’s requirements.
Are finishes and coatings suitable for display windows?
They can be, but window requirements should be specified separately from the surrounding control field. Clarity, haze, reflection, fingerprints, abrasion, touch sensing, adhesives, and optical bonding may all affect the selection.
How should durability be validated?
Use representative production materials and geometry, define the real exposure conditions, and agree on measurable acceptance criteria. Adhesion, abrasion, chemical wipe, optical, and environmental tests can then be selected for the application.
What information does ALMAX need to recommend a surface solution?
Helpful inputs include the substrate and geometry, target appearance and feel, expected touch and cleaning cycles, chemical list, temperature and UV exposure, optical or lighting needs, regulatory constraints, and required qualification tests.
