One part component epoxy adhesive glue for electronic optics and optical assembly

Best One Part Component Epoxy Adhesive Glue Manufacturer

One component epoxy adhesives play a significant role in the optical industry and assemblies. It gets used to bond several essential components together like prisms, lenses, and other optical assembly parts.

What are the General Properties of One component epoxy adhesives Used in Optics and Optical Assembly?

Each one component epoxy adhesive used for optics and optical assembly possesses a few limitations and strengths. It allows them to perform their role and become the most suitable option for a particular task. Their selection for a specific job depends on their abilities, process demands, and application requirements.

A few general attributes and properties possessed by one component epoxy adhesives used in the optical industry entail the following:

• Low Shrinkage

All one component epoxy adhesives, irrespective of their constituent material, tend to shrink in volume. It primarily happens during the curing process. It, in turn, causes undesirable stress on the various optical parts and components. Thus, it can lead to alignment and focusing problems during the assembly.

Such issues can get resolved by using an one component epoxy adhesive having low shrinkage abilities. It helps overcome the problems significantly.

• High Clarity

Optical clarity is an essential property all one component epoxy adhesives used in the optical assembly must possess. They should not result in clouding or haze after application. Furthermore, the clarity should get retained for a considerable time.

• Rapid Curing

The one component epoxy adhesives must cure substantially fast and “hard.” It is necessary to allow for appropriate polishing. Furthermore, it prevents detrimental fiber movement. Overall, a rapid and “hard” curing enables superior performance and integrity of the resultant structure.

• Low Outgassing

Optical one component epoxy adhesives should not allow for significant outgassing. Otherwise, the release of various volatile materials and substances after and during the curing process can condense over the optical surfaces. It, in turn, can lead to several quality issues.

What are the Different One component epoxy adhesives Used for Optics and Optical Assembly?

Generally, six one component epoxy adhesive types get utilized for optics and optical assembly, namely:

• Epoxies

Epoxies can bond securely to various substrates and have low outgassing properties. They tend to cure comparatively slower but have minimal shrinkage after the curing process.

Epoxies conventionally get used for bonding dissimilar materials, underfilling, and potting. Also, they can join structural reinforcements, fiber onto packages, and strain relief boots.

• Light Curable Acrylics

Light curable acrylics possess exceedingly low shrinkage and outgassing values. Additionally, they have considerable resistance to UV radiation.

Cured acrylic one component epoxy adhesives can deliver superior chemical, environmental, and thermal resistance. The curing process is exceptionally fast. Moreover, these one component epoxy adhesives promote significant flexibility.

• Elastomers

Elastomers are highly flexible one component epoxy adhesives having considerable resistance to moisture and heat. They can bond to various substrates and are ideal choices for stress absorbers.

• Anaerobics

Anaerobics can offer high strengths and quick fixture time. Also, they have high temperature and environmental resistance. It makes them suitable for bonding ferrules to fibers.

• Structural One component epoxy adhesives

Structural one component epoxy adhesives can help acquire significant strength with a curing time of fewer than two minutes. Moreover, they have an appropriate impact and environmental resistance, making them suitable for weld replacement. Furthermore, they allow for the structural bonding of metals and plastics.
