From home to high-tech: the versatile performance of bisphenol F epoxy in UHS coatings and electronics fields

 

In industrial applications, BPF epoxy resin is gradually gaining recognition in the industry. This resin is not only durable and highly protective, effectively extending product lifespan, but also offers a range of other excellent properties. At the same time, it has a lower impact on the environment and human health, helping to promote green living and sustainable development while opening up more possibilities for industrial applications.

Formaldehyde-free! Solvent-free!

 

 

When renovating or decorating a new home, have you often seen these slogans?

 

 

In our daily lives, we frequently come into contact with various types of coatings. Whether on walls, furniture, or car exteriors, coatings provide essential protection and decoration.

 

 

However, traditional paints often contain high levels of volatile organic compounds (VOCs). These substances are released into the air as the paint dries, potentially posing risks to both the environment and human health.

 

 

 

 

Common VOCs in households

 

Common VOC	Source	Health Effects
Formaldehyde	Furniture, building materials, flooring, smoke, cleaning products	May cause allergies and respiratory irritation; long-term exposure can be carcinogenic
Benzene	Paints, cleaning products, solvents, cigarette smoke, appliances	May cause headaches and nausea; long-term exposure can lead to leukemia
Toluene	Paints, cleaning products, air fresheners	Can cause headaches, dizziness, and nervous system damage
Xylene	Paints, cleaning products, solvents	May cause respiratory discomfort, headaches, and liver damage
Ethanol	Cleaning agents, disinfectants, perfumes, alcoholic products	Can cause eye and respiratory irritation
Chloroform	Disinfectants, cleaning products, solvents	May cause headaches and nausea; harmful to liver and kidneys
Chlorofluorocarbons (CFCs)	Older air conditioners, refrigerators, air fresheners	Can damage the ozone layer, indirectly affecting human health

 

To reduce the emission of these harmful substances, paint manufacturers have introduced Ultra-High-Solid (UHS) coatings.

 

 

What is UHS coating?

 

The composition of coating includes both solid components and solvents. UHS coatings reduce solvent content and increase the proportion of solids, significantly minimizing solvent evaporation during application and effectively lowering VOC emissions.

 

The benefits of choosing UHS coatings go beyond this. Their high solid content results in thicker and more durable layers. Whether on walls at home or on everyday furniture, they provide longer-lasting protection, reduce the frequency of repainting, and save both time and cost. At the same time, the application process is more efficient, as a single coat can achieve the desired result without the need for repeated layers.

 

 

 

Why are UHS coatings so effective?

 

The secret lies in their main ingredient—BPF epoxy (Bisphenol F epoxy resin).

 

BPF epoxy resin is a low-viscosity liquid epoxy with excellent electrical insulation, corrosion resistance, and strong adhesion properties. Once cured, it provides high mechanical performance, making it suitable for a variety of engineering applications, such as civil construction and electrical insulation materials. Due to its low viscosity, BPF epoxy can be blended in proportion with other epoxies, such as BPA-based resins, to further tailor its properties. Although a high crosslink density may introduce some internal stress, its outstanding durability and insulation performance make BPF epoxy resin an ideal choice for high-performance applications.

 

 

 

Multiple advantages in industrial applications

 

BPF epoxy resin demonstrates multiple advantages in industrial applications. Its low viscosity makes it easy to process, particularly suitable for solvent-free coatings or castable materials such as laminates and carbon fiber composites.

 

In addition, cured BPF epoxy exhibits excellent resistance to chemicals like acids and bases, making it ideal for protective coatings and chemical equipment. Its cured forms also offer high strength and toughness, suitable for manufacturing structural components that require high mechanical performance, such as in aerospace and automotive applications. Moreover, BPF epoxy maintains stable performance under high temperatures, making it suitable for high-temperature conditions. Its high solid content and low VOC emissions further make it an excellent choice for coatings in demanding environments.

 

 

 

An ideal material for electronic component encapsulation and assembly

 

Resin materials are widely used in the electronics industry, appearing in everyday products ranging from smartphones and computers to household appliances. These resins not only enhance product performance but also meet the growing demand for high-performance electronic devices in daily life.

 

BPF epoxy resin offers excellent fluidity and penetration, allowing it to reach tiny gaps and cavities to ensure comprehensive coverage and protection of electronic components. This characteristic provides uniform coating during assembly and maintenance, preventing moisture and contaminants from entering and thereby extending the lifespan of components.

 

In addition, BPF epoxy resin possesses strong electrical insulation properties, effectively preventing current leakage and short circuits, ensuring stable operation of electronic devices. Its outstanding heat and chemical resistance allow it to maintain stability under high temperatures and harsh environments, protecting components from external damage.

 

For electronic component encapsulation, BPF epoxy resin provides high mechanical strength, shielding internal components from external shocks and vibrations, which enhances product reliability and durability. Its low viscosity also offers excellent flow and penetration when used to produce conductive or thermally conductive adhesives, making it suitable for component connections and heat dissipation.

 

In LED encapsulation, BPF epoxy resin serves as a packaging material, delivering excellent optical performance and weather resistance, thereby prolonging LED lifespan. Overall, the application of BPF epoxy resin in electronics is largely due to its superior fluidity, low viscosity, and excellent electrical properties, meeting the stringent material requirements of modern electronic products.
