Description
Kafuter K-1668 is a high-viscosity yellow adhesive developed for positioning and securing components in electronic and electrical equipment. Its thick consistency makes it suitable for vertical application, helping the adhesive remain in place with minimal dripping or stringing during repair and assembly work.
The adhesive offers good flame-retardant performance and is designed to tolerate working temperatures from –20°C to 105°C. It is particularly useful for fixing components that may experience vibration, movement or elevated operating temperatures.

High-Viscosity Formula: The thick consistency supports controlled application and helps reduce unwanted dripping when used on vertical circuit boards or upright assemblies.
Flame-Retardant Performance: K-1668 offers stated flame-retardant properties for electronic applications. It is flame-retardant, not fireproof, and should not be applied directly to an active flame or ignition source.
Temperature Resistance: The adhesive is designed for service temperatures ranging from –20°C to 105°C, making it suitable for electronics that experience moderate heating during operation.
Component Positioning: It can help hold capacitors, coils, wires, connectors and other compatible components in position.
Reduced Stringing: The formulation provides limited stringing for cleaner and more manageable application during maintenance and assembly work.
Recommended Applications
Kafuter K-1668 may be suitable for:
- PCB component positioning
- Electronic appliance assembly
- Wire and cable securing
- Connector support
- Capacitor and coil fixing
- Power-supply maintenance
- Industrial electronic equipment
- ASIC miner repair
- Vibration-resistant component support
- Electrical-product manufacturing
Always test material compatibility before completing a large or critical application.
Application Instructions
Disconnect the equipment from power and allow heated components to cool. Clean the application area thoroughly, removing dust, oil, moisture and old adhesive. Apply an appropriate amount of K-1668 to the required component and position it correctly.
The surface requires approximately 20 minutes to dry, while full fixing takes around 24 hours. Do not move, energize or place mechanical stress on the component until the adhesive has cured sufficiently.
Essential Safety Information
The listed formulation uses toluene as a thinner. Toluene vapour is flammable and can cause eye, nose and throat irritation, headaches, dizziness and other health effects without suitable precautions.
Use the adhesive only in a well-ventilated workspace. Keep it away from flames, sparks, cigarettes, hot tools and other ignition sources. Avoid breathing vapours and prevent contact with the eyes and skin. Follow the instructions and safety information printed on the actual product packaging or safety data sheet.
