HONG YE SILICONE Electronic Potting for Time Delay Modules is a specialized waterproof and insulating Electronic Potting Compound and Silicone Encapsulant, tailored for time delay module encapsulation. As a two-component RTV silicone made of high-purity Silicone raw materials, it features low viscosity, fast room-temperature deep curing, excellent waterproof insulation, flame retardancy (UL94-V1), strong adhesion to PC/ABS/PVC and metals, complying with EU RoHS, non-hazardous, and supporting full parameter customization (around 198 characters).
Product Overview
Our Electronic Potting for Time Delay Modules is a professional low-viscosity, two-component room-temperature vulcanizing (RTV) Silicone Potting Compound developed for the encapsulation, waterproofing, insulation and protection of Time Delay Modules. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for time delay modules’ core needs—stable insulation, waterproof protection, fast curing and flame retardancy. Unlike ordinary potting silicones, it has low viscosity for easy pouring, can quickly cure at room temperature (3-5 minutes initial cure, 24 hours full cure), forms a tight protective layer, effectively protecting internal components of time delay modules, ensuring accurate time delay performance for procurement partners.
Key Features & Advantages
- Excellent Waterproof & Insulation Performance: Outstanding waterproof and moisture-proof ability, effectively isolating external moisture and dust; ultra-high insulation performance (dielectric strength ≥25 kV/mm, volume resistivity ≥1.0×10¹⁶ Ω·cm), isolating internal circuits of time delay modules, preventing leakage and short circuits, ensuring stable operation in harsh environments.
- Low Viscosity & Fast Room-Temperature Curing: Low viscosity (500±100 cps for both components), good fluidity, can easily fill tiny gaps and internal structures of time delay modules, ensuring full encapsulation without dead corners; fast room-temperature deep curing, 3-5 minutes initial cure and 24 hours full cure, adjustable operable time (30-120 minutes), greatly improving production efficiency.
- Flame Retardancy & High Safety: Flame retardant performance meets UL94-V1 standard, effectively preventing fire spread in case of abnormal heating of time delay modules, reducing potential safety hazards, and complying with international electronic product safety requirements, enhancing product safety for procurement partners.
- Strong Adhesion & Wide Compatibility: Excellent adhesion to PC, PP, ABS, PVC and various metals, forming a tight bond without detachment, avoiding gaps that lead to protection failure; compatible with most time delay module materials, no corrosion to internal components, ensuring product stability.
- High Stability & Customizable Parameters: Made of high-purity silicone raw materials, stable performance, no stratification after long-term storage (stir before use without affecting performance); parameters such as hardness, viscosity and operable time can be customized, meeting different production needs of time delay modules.
How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Fully stir Component A (粘稠 liquid) in its container to mix the settled black pigment evenly, and shake Component B (粘稠 liquid) thoroughly to ensure uniform consistency, avoiding affecting curing effect and adhesion.
- Mixing: Mix Component A and Component B at a weight ratio of 1:1, stir slowly and evenly to avoid generating air bubbles; the operable time is 30-120 minutes, so use the mixed glue in time.
- Degassing (Optional): Put the mixed potting compound into a vacuum container, degas at 0.08MPa for 3 minutes to completely eliminate air bubbles, then pour it into time delay module casings, ensuring full infiltration of all components.
- Curing: Place the encapsulated time delay module at room temperature for curing; it can enter the next process after basic curing (3-5 minutes), and achieve full curing in 24 hours. Note: Environment temperature and humidity significantly affect curing speed.
