How to Use
1. Pre-mixing: Stir Component A and Component B separately in their original containers to ensure uniform mixing of fillers and ingredients.
2. Mixing: Mix Component A and Component B at a 1:1 weight ratio, stirring thoroughly until fully fused without lumps.
3. Defoaming: Put the mixed compound into a vacuum container and degas at 0.08 MPa for 3 minutes to remove bubbles, ensuring no gaps during potting.
4. Potting & Curing: Pour the defoamed glue into LED display components, cure at room temperature or with heating. In cold weather, properly increase the temperature to accelerate curing.

FAQ
Q1: Is this product suitable for outdoor LED displays?
A1: Yes, it has excellent waterproof, anti-aging and weather-resistant properties, adapting to harsh outdoor environments such as rain, dust and UV radiation.
Q2: Can curing be accelerated in winter?
A2: Yes, you may properly heat the mixed compound or the production environment to speed up the curing process, ensuring production efficiency.
Q3: How should the unopened product be stored?
A3: Seal and store in a cool, dry place below 25℃; the shelf life is 12 months. If the colloid is layered after long-term storage, stir evenly before use, which will not affect the product performance.
Q4: What materials should be avoided during use?
A4: Avoid contact with organotin compounds, sulfur and sulfides, amine compounds, incompletely cured condensation silicone, amine-cured epoxy resin and solder flux, as these materials may cause the product to fail to cure.
Q5: Is it suitable for automated LED display production lines?
A5: Yes, it has a 1:1 mixing ratio, simple mixing and defoaming process, which is perfectly compatible with automated potting lines, improving production efficiency and product consistency.
