Transparent Silicone Potting Compounds, JF-139L
Clear silicone potting compound is a two-component, room temperature curing organic silicone potting adhesive, consisting of two liquid parts A and B. After mixing A and B components in a ratio of 10:1 (by weight), it cures through a condensation reaction to form a high-performance elastic material. The compound has good flowability, high bonding strength, and excellent properties such as aging resistance and temperature resistance.
The curing speed of this product is adjustable and can achieve deep curing, with good protection and insulation performance. It is used for fixing and insulating electronic components, moisture-proof and waterproofing of integrated circuits boards and light emitting devices, as well as coating and casting of large-area bonding seals. It is mainly used in outdoor lighting fixtures and harsh environments that require moisture resistance, corrosion resistance, and shock absorption.
