Technical Specifications
This product is a two-component addition curing silicone with a 1:1 weight mixing ratio for Part A and Part B. It requires degassing at 0.08MPa for 3 minutes before application to eliminate air bubbles. Curing time varies by temperature: 3–8 hours at room temperature, or 20 minutes at 80–100℃ for rapid curing. It is classified as non-hazardous goods, with a 12-month shelf life when stored sealed, away from acids, alkalis and impurities. Standard packaging includes 20KG and 200KG drums for both Part A and Part B, suitable for large-scale industrial use.
How to Use
Pre-Mixing Preparation: Fully stir Part A and Part B separately in their original containers to eliminate stratification and ensure uniform consistency.
Proportion Mixing: Blend Part A and Part B strictly at a 1:1 weight ratio, stirring thoroughly for 3–5 minutes until completely homogeneous.
Vacuum Degassing: Place the mixed silicone under 0.08MPa vacuum for 3 minutes to remove air bubbles and ensure a smooth sealing layer.
Application & Curing: Pour the mixture directly into the aluminum tank of liquid tank HEPA filters; cure at room temperature or heat at 80–100℃ for accelerated results.

FAQ
Q1: Will this silicone affect the surface of PC or ABS plastics?
A1: No, it is specially formulated to be compatible with PC, PP, ABS, PVC and most metal materials, causing no corrosion or surface damage.
Q2: Can the mixed silicone be stored for later use?
A2: No, the mixed adhesive undergoes a continuous curing reaction and must be used in one go to ensure optimal sealing performance.
Q3: How to handle product stratification during storage?
A3: Stratification is a natural phenomenon for silicone raw materials; simply stir the component thoroughly before use—this will not affect any performance parameters.
Q4: Is this product suitable for international shipping?
A4: Yes, it is classified as non-hazardous goods, complying with international transportation regulations and simplifying cross-border logistics arrangements.
Q5: What causes slow curing in winter?
A5: Low temperatures inhibit the curing reaction of addition curing silicone; heating at 80–100℃ for 20 minutes is recommended to ensure fast and uniform curing.
