How to Use
- Pre-Mix Preparation: Thoroughly stir Component A to evenly distribute settled fillers, and shake Component B vigorously to ensure uniformity, avoiding stratification which affects thermal conductivity and adhesion.
- Precision Mixing: Strictly follow the recommended weight ratio of Component A to B, stirring slowly and evenly for 2-3 minutes to avoid introducing air bubbles that affect sensor protection and signal transmission.
- Degassing: After mixing, place the adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate air bubbles, ensuring full penetration into tiny gaps of graphene-based sensor components.
- Curing: Pour the degassed mixture into component housings; cure at room temperature (full solidification in 24 hours) or heated to accelerate. Note: Environment temperature and humidity have a significant impact on curing speed.
