Exposed LED lights are constantly exposed to the outdoor environment, facing the corrosive effects of rain, dust, and ultraviolet rays. This makes the internal electronic components susceptible to moisture and corrosion, affecting the lifespan and lighting performance of the light fixture. Potting is a key process to solve this problem. Through professional potting technology, the core components such as the LED chips and driver power supply are completely sealed, forming an effective waterproof and dustproof barrier.

I. Core Advantages of Potting

1. Superior Waterproof Performance: After potting, the lamp can achieve an IP67 or even IP68 waterproof rating, completely resisting rain and moisture intrusion.

2. Extended Lifespan: Effectively prevents oxidation and corrosion of internal components, extending the lifespan of LED lamps by 3-5 times.

3. Enhanced Insulation Performance: Improves electrical safety levels, avoiding safety hazards such as short circuits and leakage.

4. Optimized Heat Dissipation: Professional potting compound has excellent thermal conductivity, helping LEDs dissipate heat and improving luminous efficiency.

5. Enhanced Product Texture: The surface is smooth and flat after potting, enhancing the product's aesthetics and high-end feel.

II. Applicable Adhesives and Mixing Ratios

Shenzhen Pinsu Technology recommends using gray flame-retardant epoxy potting compound AB for LED waterproof power supplies. This adhesive has the following characteristics:

1. 1. Precise mixing ratio: A:B=5:1 (by weight), ensuring excellent curing effect.

2. Fast curing speed: Cures at room temperature, gels in 2 hours at 25℃, usable time of 50 minutes.

3. Superior performance: Flame retardant up to 94V0 level, good insulation, excellent surface gloss.

4. Wide range of applications: Suitable for insulating and pouring small electronic components such as LED waterproof power supplies, capacitors, and transformers.
