With the increasing awareness of health and hygiene, ultraviolet disinfection lamps are widely used in various scenarios such as medical care, home appliances, and public environments. These types of products work in environments with high temperature, high humidity, and high ultraviolet radiation for a long time, especially the lamp board (control circuit board) part, which requires reliable waterproof treatment to avoid electrical short circuits, device corrosion, and other faults caused by water vapor intrusion.
UV disinfection lamp
Among numerous sealing solutions, the SIPC 1816 silicone series has become an ideal choice for UV disinfection lamp manufacturing enterprises due to its excellent fluidity, waterproofness, UV resistance, and temperature stability. This article will provide a detailed analysis of how to use SIPC 1816 to achieve deep sealing protection for lamp boards and improve the overall reliability and lifespan of the product, based on specific application cases.
1、 The application challenges of ultraviolet disinfection lamps
When the ultraviolet lamp works, it produces high-intensity ultraviolet light, especially in the UV-C band (200-280nm), which not only has a killing effect on bacteria and viruses, but also poses a challenge to the internal materials of the lamp. As a control center, the lamp board often integrates important components such as LED drivers, timing modules, and power circuits, and imposes the following performance requirements on the adhesive:
LED waterproof sealing
Excellent UV aging resistance, preventing colloids from powdering and cracking due to prolonged UV exposure;
Excellent fluidity, able to penetrate into device gaps and achieve deep sealing without bubbles;
Good high temperature resistance (80 ℃~120 ℃), ensuring long-term stable operation;
Strong waterproof and moisture-proof ability, preventing condensation or moisture from entering and causing short circuits;
Good electrical insulation and flame retardancy ensure the safe operation of circuit boards.
2、 Solution recommendation: SIPC 1816 silicone sealant
▶ Product Introduction
SIPC 1816 A/B is a two-component, condensation type room temperature curing silicone gel designed specifically for electronic component encapsulation and protection applications, with excellent weather resistance, electrical insulation, and structural adhesion.
▶ Main performance advantages
Project performance
Dual component (A/B), flexible mixing ratio
Low viscosity, good flowability, easy to process
Curing method: room temperature or heating curing, alcohol removal reaction without corrosion
The operation time can be flexibly adjusted according to temperature and curing agent ratio
Long term temperature resistance range of 80-120 ℃, with a peak value of up to 150 ℃
UV resistant silicon-based structure, resistant to 280nm ultraviolet radiation without fear of aging
Flame retardant performance UL 94 V-0 flame retardant certification
Adhesive performance can adhere well to most plastic, metal, and glass materials without the need for a primer
Environmentally friendly and safe, free from halogens and solvents, compliant with RoHS standards
3、 Why choose SIPC 1816?
Among numerous sealing materials, SIPC 1816 silicone products exhibit multiple technological advantages, particularly suitable for UV light source applications:
✅ Anti UV aging without yellowing: no powdering or cracking after long-term UV-C irradiation;
✅ Deep sealing with zero dead corners: low viscosity and fast leveling, suitable for complex structural devices;
✅ Electrical insulation flame retardant: protects the stable operation of the lamp board circuit;
✅ Resistant to high and low temperature cycling: suitable for various installation environments;
✅ Environmentally friendly and non corrosive: Deathanol curing does not affect components, metals, or PCB solder joints.
For high-performance and long-lasting ultraviolet disinfection lamp products, choosing a reliable waterproof and UV resistant sealing adhesive is the key to ensuring quality. SIPC 1816, with its excellent performance, has been widely used by many brands in LED disinfection lamps, air purifiers, medical UV modules and other products, becoming a star product in the field of electronic encapsulation and protection.
