Product Application

Liquid Naphthalene Type Epoxy Resin is mainly used for high-end electronic packaging, aerospace composite materials, electronic inks, and more.

High-Performance Composite Materials: It can be used for aerospace, automotive manufacturing, and sports equipment, it is used to produce high-strength, heat-resistant, and corrosion-resistant composite parts, including aircraft components, wind turbine blades, and racing car parts.

Electronic Packaging Materials: Due to its excellent heat resistance and electrical insulation properties, it is mainly uesed for packaging high-end electronic products, such as microelectronic devices and semiconductor chips. It helps improve product reliability and extend service life.

Optoelectronic Materials: Naphthalene epoxy resin is can also used in optoelectronics, including LED packaging and optical fiber coatings. Its high transparency and adjustable refractive index enable the effective transmission of optical signals.

Special Functional Materials: In applications requiring the unique characteristics of the naphthalene ring (such as fluorescence or photoelectric conversion efficiency), it can also be developed for high-tech products, including sensors and optoelectronic displays.

FAQ

Q: Can the composite material made of this resin withstand long-term high temperature environments? What is the temperature range?

A: Liquid Naphthalene epoxy resin has excellent high temperature resistance, usually its long-term use temperature can reach more than 150°C, short-term temperature resistance can exceed 200°C, very suitable for the production of composite parts that need to work in high temperature environment.

Q:How does the use of this resin package affect the long-term reliability of electronic components?

A: Naphthol epoxies provide excellent electrical insulation and thermal stability, effectively reducing the impact of thermal cycling and mechanical stress on electronic components, thereby extending the operating life of equipment and improving overall reliability.

Q: Tightly sealed in a ventilated space in RT. A nonflammable material.- Is this all right?

A: Yes, advise to fill the top of the package with nitrogen for protection after each use.

Q: Does N140S as supplied contain any curing agent? Or we need to add curing agent for curing? If we need to add, any recommendation for amine catalyst?

A: N-140S does not contain curing agents and is a one-component epoxy resin that requires additional curing agents for curing. If the subsequent application requires high heat resistance, 44DDS can be used for curing, and D-230 curing agent can be used if flexibility is required.

Q: What temperature and for how long do we need to heat the material for liquid consistency? And once it becomes liquid how long will it be stable in liquid condition?

A: Liquid Naphthalene Type Epoxy Resin is easy to cryallize and It is recommended that the resin can be heated at 100 ° C until it is completely melted before use, and it is generally need more than 3 hours. when it completely melted, sealed with nitrogen, and then airtight storage, the liquid state can exist for about 5 days,after one week there is a risk of becoming solid. If you need a liquid state , it is recommended to mix with other varieties of epoxy resin in advance, so that it can be stored in liquid for a long time.
