Description

Technical field

[0001] The invention relates to the technical field of adhesives and preparation, in particular to a LED transparent organosilicon potting glue with high refractive index and high viscosity and a preparation method thereof. Background technique

[0002] Potting glue is used for bonding, potting, sealing and coating protection of electronic components. The potting glue is fluid and liquid before curing. The viscosity of the glue varies according to the material, performance and production process of the product. After curing, the potting glue can realize its use value. After curing, it can play the role of waterproof, moisture-proof, insulation, dustproof, heat conduction, confidentiality, temperature resistance, corrosion resistance, shock resistance, etc. It has been widely used in electronic device manufacturing , Is an important processing material indispensable for the electronics industry.

[0003] The LED, known as the fourth-generation light source, has the...
