There are many types of adhesive glues on the market, including UV glue, epoxy resin glue, PUR glue, hot melt glue, and instant glue. With growing demand, adhesives featuring various technologies are continuously emerging. Many customers are uncertain about choosing between UV glue and epoxy resin glue. In fact, these two types of adhesives differ significantly in composition, curing methods, bonding strength, transparency, and environmental impact. UV glue is characterized by fast curing and high transparency, making it ideal for bonding transparent materials. In contrast, epoxy resin glue offers high strength and excellent heat and corrosion resistance, suitable for structural applications that require long-term durability. When selecting an adhesive, it is essential to consider specific application needs and material properties to make the best choice.
Coating adhesives and conformal coatings are used to protect electronic components. Coating adhesives focus on physical protection and structural support, protecting against moisture, dust, etc. and enhancing impact resistance, used in LED lighting, etc. Conformal coatings mainly prevent moisture, salt spray and mildew, suitable for outdoor, marine equipment and other harsh environments. They differ in functions, compositions, characteristics and application scenarios.
LED silicone is the general term for organic silicone materials in the LED photoelectric industry. Due to the weak anti-ozone ability of epoxy, the colloid turns yellow, affecting the light transmission effect, and the silicone material has excellent properties such as anti-atmospheric aging and ultraviolet aging, and epoxy resin has been replaced by LED silicone material in high-end product applications.
This article delves into the crucial applications of electronic adhesives in electronics and electrical engineering. Silicone sealants and potting compounds are highlighted. Their properties and functions are detailed. Silicone gels offer advantages for potting, like easy pouring and transparency. Applications include foam silicone rubber in computer memory, flame-retardant compounds in TV high-voltage products, and single-component silicone as a coating. It showcases the diverse uses and value of electronic adhesives.
