Technical Specifications (HY-9320)
Curing pre-performance: Both Component A and B are colorless transparent liquids with a viscosity of 500±100 mPa.s, mixed at a 1:1 weight ratio. Curing post-performance: Shore A hardness of 20±3, refractive index of 1.41, 95% light transmittance at 450nm (2mm), volume resistivity of 1.01015 Ω.cm, and thermal expansion coefficient (CTE) of 280 ppm/℃. All parameters are for HY-9320 model, with other models available for different application needs.
How to Use
1. Mixing & Deaeration: Blend Component A and B in a dry container with thorough stirring, then stand to defoam naturally or remove bubbles by vacuum pumping to avoid air bubbles in the encapsulation layer.
2. Component Preparation: Clean and dry the electronic components to be encapsulated thoroughly, keeping LED chips dry before potting to ensure bonding and curing effect.
3. Potting: Pour the mixed silicone glue into the components, ensuring full infiltration of all parts and fine gaps.
4. Curing: Place the encapsulated components in an oven for curing; adjust the curing speed flexibly by changing the oven temperature according to production needs.

FAQ
Q1: What is the shelf life of this high transparency electronic potting silicone?
A1: The shelf life is 12 months when stored in a cool and dry place with sealed packaging for both Component A and B.
Q2: What substances should be avoided during use to prevent uncuring?
A2: Avoid contact with oxygen, phosphorus, sulfur, ethynyl, peroxides and metal compounds such as lead, tin and cadmium, which will cause the silicone to fail to cure normally.
Q3: Can the mixed silicone glue be stored for a long time?
A3: No, the mixed A and B components should be used up in time; long-term storage will lead to gradual curing and loss of usability, avoiding material waste.
Q4: Is this product a dangerous good for transportation?
A4: It is a non-dangerous chemical and can be transported according to general chemical transportation standards, with no special transportation restrictions.
Q5: How to store the product after opening if it is not used up?
A5: Seal the opening of Component A and B tightly immediately after opening and use, avoiding contact with air moisture, which will not affect the subsequent use effect.
