DOWSIL 3-1944HP RTV One-part translucent silicone for pin solder joint coverage
Product Introduction of DOWSIL™ 3-1944 HP RTV Coating
Part 1: Basic Properties
DOWSIL™ 3-1944 HP is a one-part, translucent RTV silicone coating with excellent flowability, fast tack-free time, and flame resistance (UL 94 V-0 rated). Its UV indicator enables automated inspection, and it is solvent-free for environmental friendliness.
Part 2: Product Description
DOWSIL™ 3-1944 HP cures by absorbing ambient moisture, eliminating the need for ovens. It forms a soft, low-stress elastomer ideal for protecting delicate components (e.g., solder joints, pins). The fast cure (7-minute tack-free at 25°C) can be accelerated with mild heat (<60°C) for higher throughput.
Part 3: Key Features
- UV Indicator: Enables visual inspection under UV light for coverage verification.
- Flame Resistance: UL 746C 94 V-0 certified for high-reliability applications.
- Low Stress: Shore A 36 durometer minimizes mechanical stress on components.
- Shelf Life: 12 months at 25°C.
Part 4: Applications
Designed for electronics protection, typical applications include:
- Pin/Solder Joint Coverage: Shields PCB joints from oxidation and short circuits.
- Thin Section Encapsulation: Ideal for sensors and microelectronics.
- Spot Protection: Selective coating for connectors or critical areas.
