Product Overview
Our Electronic Potting for Strain Gauge Bridges is a professional Silicone Potting Compound developed for the encapsulation, sealing, precision protection and insulation of Strain Gauge Bridges. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for strain gauge bridges’ core needs—strain detection precision retention, stress interference resistance and signal stability. Unlike ordinary potting silicones, it has low modulus and cures without shrinkage, does not affect the strain sensitivity of gauge bridges, effectively isolates moisture, dust and external stress, resists corrosion and ozone, and has excellent adhesion to PC, PMMA, PCB and strain gauge metal foils, protecting internal bridge circuits, ensuring long-term stable strain measurement for procurement partners.
Key Features & Advantages
1.Strain Detection Precision Protection & Stress Resistance: Low modulus, non-shrinking curing formula, no interference with the strain sensitivity of strain gauge bridges, ensuring accurate signal response to micro-strain changes; effectively absorbs external mechanical stress and vibration, avoiding strain distortion caused by potting colloid, ensuring precise strain measurement data.
2.High-Precision Signal Transmission & Dimensional Stability: Cures without shrinkage, maintaining precise dimensional compatibility with strain gauge bridges, not affecting their signal transmission speed and measurement accuracy; cured colloid is soft and flexible, adapting to the micro-deformation of strain gauges, avoiding damage to fragile bridge circuits and ensuring consistent signal stability.
3.Superior Temperature Adaptability & Heat Dissipation: Operating stably from -60℃ to 220℃, with outstanding high and low temperature resistance; integrated thermally conductive potting compound properties efficiently dissipate slight heat generated by bridge circuit operation, avoiding overheating-induced performance degradation and component damage; adapts to extreme industrial, aerospace and outdoor temperature environments.
4.Strong Adhesion & Material Compatibility: Excellent adhesion to PC (electronic insulation board), PMMA (acrylic), PCB, strain gauge metals (copper, nickel-chromium alloy) and plastic housings, forming a tight seal without detachment; no chemical reaction with strain gauge materials, avoiding material degradation and ensuring gauge bridge service life; two-component design, easy to mix evenly, optional vacuum defoaming (0.01MPa for 3 minutes), supports room temperature or heated curing, full curing in 24 hours, suitable for batch gauge bridge production.
5.High Stability & Dual-Formula Options: Available in high-purity addition curing silicone (low volatility, non-toxic, high stability) and enhanced thermally conductive potting compound (for high-load strain gauge bridges), meeting different application needs; low volatility, high strength, no stratification after long-term storage (stir before use without affecting performance); mixed glue can be used up at one time, reducing waste and procurement costs.
How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Fully stir Component A in its container to mix the settled filler evenly, and shake Component B thoroughly to ensure uniform consistency, avoiding affecting curing effect, insulation and adhesion to gauge bridge components, which is crucial for strain measurement precision.
- Mixing: Mix Component A and Component B according to the specified weight ratio (customizable), stir slowly and evenly to avoid generating air bubbles, which may affect insulation, sealing and signal stability of strain gauge bridges.
- Degassing (Optional): Put the mixed potting compound into a vacuum container, degas at 0.01MPa for 3 minutes to completely eliminate air bubbles, then pour it into strain gauge bridge packaging molds or casings, avoiding overflow that affects measurement performance.
- Curing: Place the encapsulated strain gauge bridge at room temperature for curing or heat to accelerate curing; enter the next process after basic curing, and full curing takes 24 hours. Note: Environment temperature and humidity significantly affect curing speed and final performance.
