One of the most important capabilities in almost all permanent coating systems is to firmly adhere to the substrate after film formation. In fact, the adhesion of the coating film is a necessary condition to provide long-term protection and aesthetics. Alfa Chemistry has a variety of surface coating technologies that can functionalize a variety of substrate types to improve adhesion behavior.
Adhesion-promoting nano-coating can significantly change your surface behavior to improve the surface adhesion properties of various functional adhesives and coatings. In addition, these adhesion-promoting coatings are nano-scale coatings that do not increase significant thickness and help minimize package size. Our adhesion-promoting nano-coating and treatment can improve the performance of almost all products that require a strong bond, which can resist delamination under the most extreme conditions.
The use of our adhesion promotion coating technology in electronic products and other applications has many performance advantages. Together we create durable products! Want to know more? Contact us to see how we can help!
Does Your Product Need Adhesion Promotion Coating?
Adhesion-promoting surface coating technology can be used to solve various surface-related adhesion problems. The following examples illustrate that adhesion-promoting nano-coatings will help improve your surface performance.
- Desire to eliminate surface roughening
- Traditional bonding technology is not feasible
- Some are experiencing bad failure modes
- Poor adhesion between substrate and adhesive
- The component is experiencing an undesired failure mode
- The current viscosity increasing process is too labor-intensive
- Desire to move to the substrate with difficult bonding characteristics
Adhesion Promotion Coating Performance
Challenging interface bonding requires an in-depth understanding of the chemistry involved. Alfa Chemistry uses its unique expertise to achieve the bonding of materials to go beyond traditional solutions. We can customize molecular superglue polymers with specific functions to connect to both sides of the interface to produce the strongest adhesion.
In order to bond the materials to each other, we can provide you with the following services:
- Create a customized molecular-level adhesion interface
- Provide permanent chemical primer (such as hydrophilization)
- Development of dedicated bonding processes (such as low-temperature bonding)
Our adhesion-promoting coating technology can improve the adhesion and adhesion characteristics of the containing surface. By using adhesion-promoting nano-coating to directly functionalize the substrate surface, delamination and adhesion failure are significantly reduced.
