PCB Moisture-Curable Elastic Adhesive Dispensing for Waterproof & Anti-Static Protection | Second Intelligent

 In the electronics industry, ensuring the long-term reliability of PCB assemblies requires more than soldering quality—it also depends on waterproofing, moisture protection, vibration resistance, and anti-static insulation.

A client approached Second Intelligent seeking a fully automated solution to dispense Single-Component, Moisture-Curable, Elastic Adhesive (White) on their PCB boards to enhance environmental protection and component robustness.

Their adhesive was supplied in a 310ml cartridge, commonly used for RTV-type moisture-curing elastomers with medium-to-high viscosity.

 1.Customer Background & Requirements

The client manufactures LED lighting modules and electronic control boards. Their PCB contains multiple sensitive components—LEDs, sensors, ICs, connectors—and requires precise bead and dot dispensing to achieve full protective coverage.

Customer Pain Points

Components closely spaced → manual dispensing machine easily contaminates solder pads

Moisture-curable elastic adhesive → medium/high viscosity, difficult to control manually

Needs uniform glue coverage for waterproofing and anti-static protection

Inconsistent manual output → unstable product quality, high rework rate

Large production volume → efficiency too low with hand dispensing

 

Adhesive Specification

Type: Single-Component, Moisture-Curable, Elastic Adhesive (White)

Features: Waterproof, moisture-proof, anti-static, vibration-resistant

Packaging: 310ml cartridge

Curing: Room-temperature moisture curing

Function: Environmental sealing + mechanical reinforcement


Typical Application Areas

● LED lamp bead waterproof sealing

● IC and sensor edge sealing

● Component foot reinforcement and insulation

● Moisture barrier for exposed solder joints

● Anti-static isolation coating in sensitive areas

2. Second Intelligent’s Customized Dispensing Solution

Based on the adhesive type and PCB structure, Second Intelligent designed a professional solution tailored for waterproofing & moisture-curable adhesive dispensing machine.
