How Resin-Coated Decals or Domes Are Made
Resin-coated decals, commonly known as domes, are an innovative solution for brand identification and promotion. These three-dimensional labels stand out not only for their aesthetic appeal but also for their durability and versatility in various industrial and commercial applications.
Strength and Durability
One of the main advantages of domed decals is their resistance to impacts and scratches. The top layer of polyurethane resin acts as a protective shield, safeguarding the printed design from physical damage and wear. Additionally, this resin has self-healing properties, allowing the surface to recover its original shape after minor impacts. This feature is especially valuable in industrial environments, where labels are exposed to harsh conditions.
Clarity and Fade Resistance
Polyurethane resin is highly transparent and offers excellent UV resistance. This ensures that colors and graphics under the dome remain vibrant and sharp for years, even with prolonged sun exposure. Unlike other resins, polyurethane resists yellowing and clouding, maintaining a pristine appearance over time.
Resistance to Environmental and Chemical Conditions
These decals are waterproof and resistant to both fresh and saltwater, as well as mild acids and bases. Their flexibility allows them to withstand extreme temperatures, with an operational range from -40°C to 60°C (-40°F to 140°F). This makes them ideal for outdoor applications and demanding industrial environments.
Aesthetic Appeal and Customization
The three-dimensional, glossy effect of domes adds a touch of sophistication to any product. Their smooth, raised surface invites tactile interaction, creating a sensory experience that enhances brand perception. Additionally, these decals can be customized in various shapes, sizes, and colors, adapting to the specific needs of different brands and products.
Versatile Applications
Resin-coated decals are suitable for a wide range of surfaces, including metal, plastic, and glass. They are commonly used for product identification, brand logos, control panels, and signage. Their durability and resistance make them a preferred choice in industries such as automotive, appliances, and industrial equipment.
Considerations for Implementing Domes
When using domes, it’s important to consider that they are thicker and heavier than standard labels, which may require stronger adhesives. Additionally, sharp edges or very small areas may not be suitable for the resin-coating process, due to the surface tension properties of the resin.
The production time is also longer, as the resin requires a curing period that can exceed 12 hours. Therefore, it is recommended to use this technique selectively to maximize its impact and efficiency.
Structure of Domes
Domes are composed of several layers that work together to provide durability, resistance, and an attractive visual finish. Each element plays a key role in the quality and adhesion of the product. Resin-coated decals or domes are made up of five distinct layers:
Liner or backing – Protects the adhesive until the moment of application.
Adhesive – Ensures a strong and long-lasting bond on various surfaces.
Substrate – The base material on which the design is printed, providing stability and resistance.
Printed Artwork – The graphic design layer, featuring vibrant and well-defined colors.
Transparent Resin Capsule – Creates the 3D effect, protects the print, and provides a glossy, durable finish.
These components ensure that domes are both an aesthetic and functional solution for multiple industrial applications. Below, we’ll show you a descriptive image with the parts that make up a resin decal or dome, mentioned above:
In summary, resin-coated decals or domes offer a unique combination of aesthetics and functionality. Their ability to enhance product appearance, combined with durability and resistance, makes them a valuable tool for businesses looking to stand out and protect their brand identity in challenging environments.
At Chapigraf, we go the extra mile by using resins free of mercury, heavy metals, and phthalates in the production of resin-coated labels and domes. We also comply with the following European and international regulations: Regulation EC 2017/852 (Mercury-Free), RoHS Directive 2011/65/EC (Restriction of Hazardous Substances), REACH Regulation EC 1907/2006 (Chemical Safety), ELV Directive 2000/53/EC (End-of-Life Vehicle Standards), and CE Directive 88/378/EEC (Toy Safety Standards).
