MacDermid Alpha Micromax 5056 Bendable White Reflector Paste for Flexible LED
Type: Bendable White Reflector Paste
Application: Flexible LED / Reflective Solder Mask
Color: White
Solids: 48–53%
Shelf Life: 6 months
Micromax 5056 is a solvent-based, screen printable paste for flexible reflective solder mask applications. It will not crack after curing on flexible CooLam, maintains white color during and after processing for better reflectivity, and adheres to copper clad substrates and conductors. A 25μm film thickness is recommended.
Micromax 5056 from MacDermid Alpha is a solvent-based, screen printable polymeric paste formulation for applications that need a flexible, reflective solder mask after curing. It offers rapid curing and holds adhesion to copper clad substrates and conductors. The paste is suited to LED applications on flexible CooLam as well as other substrates. Solder mask processing conditions vary by equipment, but a general drying recommendation is 130–150°C.
The paste carries 48–53% solids, density 1.35 g/cm³, and a maximum service temperature of 120°C. A film thickness of 25μm is recommended. Cured film shows no cracking after a 45° bend on flexible CooLam, and pencil hardness reaches 1H or higher. White color is maintained during and after processing, which supports consistent reflectivity. Store sealed at 5–30°C; unopened shelf life is 6 months.

Frequently Asked Questions
Why is 5056 described as bendable?
The TDS lists flexibility as no cracking after a 45° bend, tested on flexible CooLam. This lets the cured reflector layer follow the movement of a flexible LED circuit without breaking the reflective surface.
How does 5056 maintain reflectivity over time?
The Product benefits section states that 5056 maintains white color during and after processing. Keeping the white tone stable supports consistent light reflection across the LED assembly.
What film thickness should I target for 5056?
The TDS recommends 25μm. This thickness balances reflectivity, adhesion, and flexibility on flexible CooLam.
Does 5056 need a specific thinner?
Micromax 8260 is the listed solvent or thinner. Using the recommended thinner helps keep viscosity and print behavior consistent.
What curing schedule is recommended for 5056?
Dry at 130–150°C for 5–10 minutes. The TDS recommends drying in a well-ventilated oven or conveyor dryer where exhaust meets environmental regulations.
Which substrates are recommended for 5056?
The TDS positions 5056 primarily for flexible CooLam, and also notes suitability for other substrates. Adhesion is maintained on copper clad substrates and conductors.
How should opened containers of 5056 be stored?
Keep containers tightly sealed at 5–30°C in a clean, stable environment. Unopened shelf life is 6 months from shipment. Some settling may occur, so mix thoroughly before reuse.
