MacDermid Alpha Micromax 5450 High-Conductivity Platable Silver Termination for Dipped Chip Resistors
Type: Platable Silver Termination
Application: Chip Resistor, Dipping
Solids: 58.5–63.5%
Shelf Life: 3 months refrigerated
Micromax 5450 is a polymeric platable silver composition for chip resistor edge termination. It is applied by dipping and cured at low temperature. It offers single composition thermosetting resin, excellent platability with high plated adhesion, excellent dipping performance, and high conductivity.
Micromax 5450 from MacDermid Alpha is a polymeric platable silver composition intended for chip resistor applications as an edge termination. It is applied by dipping and then cured in a low temperature oven. The composition is a single-component thermosetting resin, which simplifies handling and process control. It offers excellent platability with high plated adhesion, excellent dipping performance, and high conductivity.
The paste carries 58.5–63.5% solids and a viscosity range of 18–20 Pa.s. Micromax 9245 is the recommended thinner, though thinning is not normally required since the composition is optimized for dipping. Dipping should be performed in a clean, well-ventilated area at 20–23°C. After dipping, allow parts to level at room temperature, then dry at 150°C for 10 minutes. Cure at 200°C peak held for 30 minutes. Store sealed at 0–5°C; room temperature storage is not recommended. Unopened shelf life is 3 months from date of shipment.

Frequently Asked Questions
Why is 5450 applied by dipping instead of screen printing?
The TDS states that 5450 is intended for chip resistor edge termination and is applied by dipping. This method is well suited to forming terminations on the edges of chip resistors after they are separated.
What curing schedule does 5450 require?
After drying at 150°C for 10 minutes, cure at 200°C peak held for 30 minutes. The TDS lists low temperature curing as a key characteristic.
Does 5450 need a specific thinner?
Micromax 9245 is the recommended thinner. The composition is optimized for dipping, and thinning is not normally required. Use the recommended thinner only for slight viscosity adjustments or to replace evaporation losses.
What are the plating characteristics of 5450?
The TDS lists excellent platability with high plated adhesion as a product characteristic. This supports reliable performance when the termination is subsequently plated.
How should 5450 be stored?
Store refrigerated at 0–5°C. Room temperature storage is not recommended. Unopened shelf life is 3 months. Allow the material to equilibrate to room temperature before opening to prevent moisture pickup from condensation.
What is the conductivity of 5450?
The TDS lists high conductivity as a product characteristic. This supports low-resistance termination performance in chip resistor assemblies.
What room temperature is recommended for dipping 5450?
Optimum dipping characteristics are generally achieved at 20–23°C. Bring the material to this temperature before starting the dipping process.
