Structural Bonding Solutions
Shear and tensile strength are critical in many applications, filling large gaps is also critical in many electronic devices. A well-designed adhesive will improve structural integrity and dampen vibration, movement, and related stresses.
Adhesive applications using robots or automatic dispensing systems further increases the efficiency, accuracy, and consistency in the end use application.
Structural Adhesives
Structural adhesives are thermoset or thermoplastic polymers that are available in a few different types of chemistries: epoxies, urethanes and acrylics are the most common.
Ionic cleanliness, and consistent performance are also critical to most applications.
Structural adhesives are responsible for filling gaps to prevent contamination and block the entrance of liquids and the environment.
Adhesives are an Effective Way to Fasten
Adhesives are an effective way to fasten many of the next-generation materials, modules or components. Especially small components or composites and ceramics that are sometimes sensitive to the focused stress points that welds, and threaded fasteners create. Rather than creating stress points, adhesives disperse the stress of a joint across the entire bonded surface. This reduces the risk of distortion, which effects the performance of the assembly. Structural adhesives are also useful for bonding different metals or substrates. Many structural adhesives have lower modulus or are highly filled to match CTE variances and alleviate stresses and strains placed on bonded assemblies. Metals that are exposed to thermal cycling, or if galvanic corrosion (an electrochemical reaction that occurs between some metals) is a risk in certain applications. Structural adhesives provide an inert barrier between corrosive metals while naturally providing a water barrier.
