What is pressure sensitive adhesives for decorative films?
For the next generation of coatings that turn into painting pressure sensitive adhesives
In addition, it has been attracting attention in recent years as a next-generation coating technology that can replace painting because it not only increases the degree of design freedom, but also contributes to reducing CO2 emissions and improving the efficiency of the production process.
artience group has a wide range of products that can be proposed for each layer of decorative film that has a multi-layer composition.
On this page, we will explain the features and benefits of decorative films, the functions of pressure sensitive adhesives that play an important role in demonstrating their characteristics, and introduce TOYOCHEM 's pressure sensitive adhesives products for decorative films.

Features of decorative films
- Heat resistance
The heat resistance of decorative films is a very important property, especially in the automotive and electronics industries. This is because the product must maintain its performance in high-temperature environments and prevent deformation and degradation.
When using decorative films, especially in high-temperature environments, adhesive materials with excellent high-temperature adhesion are required. For example, a special formulation of acrylic pressure sensitive adhesives suppresses peeling and shifting even at high temperatures, and achieves high heat resistance.
- Weatherability
Weathering refers to the resistance to effects such as UV rays, heat, moisture, and oxygen in outdoor environments. In the case of decorative films, resistance to fading and degradation is particularly important.
Decorative films are often used in products used outdoors, such as automotive exterior parts, outdoor advertising, and building materials. Therefore, high weather resistance is required to maintain aesthetics and functionality over a long period of time.
- Design
The design quality of decorative films is an important factor in increasing the added value of products and stimulating consumers' willingness to buy. Especially in fields such as automobiles, home appliances, and mobile devices, it has made significant contributions to product differentiation and the creation of a sense of luxury.
Advantages of Decorative Films in Automotive Painting
Decorative films not only increase the degree of design freedom, but also contribute to reducing CO2 emissions and improving the efficiency of the production process, making them a new choice for automotive coating as a next-generation coating technology.

Process reduction |
Painting, which is a conventional coating technology, requires five processes to complete the part: priming, drying, topcoating, and drying. On the other hand, decorative film molding, which is a next-generation coating technology, is completed in three processes: part molding/film printing, pasting, and trimming. |
|
Cost Savings |
Decorative films are more advantageous than painting in terms of initial investment and operating costs, as well as reduced equipment space (no painting line required), reduced labor costs (simplified work processes), and reduced material loss. |
|
Reduction of environmental impact (CO2 emissions) |
Decorative films can significantly reduce the environmental impact compared to painting due to their low VOC (volatile organic compound) emissions, the elimination of the need for painting booths and drying ovens, the reduction of energy consumption, and the reduction of water consumption. |
|
Diverse designs |
The design of decorative films is constantly evolving with technological advancements, from the diversity of colors and patterns, the expression of textures, the support for 3D shapes, the fusion of functionality and design, the expression of diverse materials, customization, and response to trends. |
pressure sensitive adhesives plays a crucial role in ensuring that this decorative film is properly applied to the product and maintains its functionality over time.
pressure sensitive adhesives role
| Adhesive strength | pressure sensitive adhesives is responsible for ensuring that the decorative film adheres securely to various materials (plastic, metal, glass, wood, etc.). Proper adhesion prevents the film from peeling off or air bubbles entering. |
|---|---|
| Heat resistance | Especially in automotive applications, it is necessary to maintain adhesion even in high-temperature environments. By using heat-resistant pressure sensitive adhesives, you can maintain the functionality of your decorative film over time. |
| Compatible with a wide range of materials | Since decorative films are applied to a variety of materials, pressure sensitive adhesives must also be able to handle a wide variety of materials. For example, pressure sensitive adhesives have been developed that can be applied to polypropylene (PP) and glass, which are considered difficult to bond. |
| Formability | Decorative films may also be applied to products with three-dimensional shapes. The characteristics of pressure sensitive adhesives that can handle such complex geometries are important. |
| Functionality granted | By adding functionality to the pressure sensitive adhesives itself, you can increase the added value of the decorative film. For example, the use of pressure sensitive adhesives, which has properties such as thermal insulation and electrical conductivity, can expand the application of decorative films. |
TOYOCHEM Solution
pressure sensitive adhesives for decorative films require a variety of performances, such as high durability that does not peel off even in harsh vehicle environments, tracking of complex shapes, elongation of coating films, adhesion to various substrates, and workability when attaching (molding) to parts.
TOYOCHEM makes use of the polymer design technology we have cultivated over many years to make proposals and customized designs according to the location of use (vehicle exterior/vehicle interior), molding methods (hand-pasting, OM-D molding, IM-D molding, etc.), and adaptation to various conversion conditions (coating method, printing method).
for decorative films pressure sensitive adhesives design image
Decorative films are divided into four types according to their characteristics as design images.
TOYOCHEM can develop our own products that combine these four types, so please contact us once.
| Type① | Low tack and strong adhesion | It has excellent plasticizer resistance, gasoline resistance, and proper reapplication. |
| Type② | High tack and strong adhesion | It can be strongly bonded to olefin materials such as PP and PE. |
| Type③ | Stress relaxation control | It has excellent adaptability to molding and lamination methods and step tracking. |
| Type④ | Durability | It is highly resistant to heat, gasoline and blister. |
