1 , High transparency. A key advantage of transparent sealant is that it remains clear after application, allowing you to clearly inspect the sealed electrical components. If a component malfunctions, you can quickly locate the fault and replace the defective part.

2 , Low shrinkage and does not damage precision components. Low volumetric shrinkage during curing (typically ≤1% ), it does not generate internal stress, thereby preventing compression, deformation, or damage to precision components such as chips, circuit boards, and miniature sensors, and ensuring product stability.

3 , Flame-retardant and resistant to acids and alkalis. Even in challenging environments—such as those exposed to acidic or alkaline conditions, or contaminated by oil—it can be used reliably. This adhesive boasts excellent resistance to acids and alkalis, while also repelling oil, dust, and moisture, making it safe and dependable for use.

4 , high strength and excellent adhesion. The formulation offers construction flexibility and is compatible with a wide range of substrates, including metals, plastics, and glass. It provides strong adhesion, ensuring that encapsulated products are robust and reliable, while remaining non-corrosive to these materials. Once cured, it exhibits enhanced strength and can withstand various external environmental stresses.

5、  Good temperature resistance. This adhesive exhibits excellent thermal stability, maintaining consistent performance across both high- and low-temperature environments.

The specific applications are as follows:

LED Device and Lighting Module Packaging ‌
High-transparency potting compounds are widely used in ‌ High power LED , patch LED 、 LED Line lights, LED Display screen ‌ Packaging of related products. Featuring UV resistance and yellowing‑inhibition properties, it ensures that luminaires remain bright and maintain performance over long-term use.

Precautions for using transparent potting compound:

Monitor component status : Transparent potting compound consists of two components, both of which are transparent. During use, it should be noted that slight yellowing in one of the components may be related to storage conditions. In such cases, the compound should not be immediately deemed unusable; instead, a series of performance tests must be conducted. If the results meet the required standards, the compound may continue to be used.

Correctly Understanding the Yellowing Phenomenon : After curing, the transparent potting compound forms a glossy, flexible film with an overall transparent body; however, after prolonged use, it may develop a slight yellowing. Many people mistakenly attribute this to a quality issue, but in fact, the yellowing is caused by UV exposure and is a normal phenomenon. When purchasing, simply opt for high‑quality products—any yellowing that does occur will not compromise the compound’s performance.
