Electronics & filtration encapsulation

Low-exotherm, low-shrink potting that protects sensitive assemblies.

The challenges in this industry

  • Heat damage to delicate electronics during cure
  • Shrink-induced stress on bonded joints
  • Long pot life with rapid demold

How MCPU shows up

MCPU works directly with formulation teams in electronics & filtration encapsulation to qualify polyurethane chemistry against the specific spec, line, and end-use environment. We don’t hand off a generic SKU — we run pilot trials, iterate, and ship to your target.

Case story

MCP 3335 is the encapsulant of choice for a Fortune-500 industrial-filtration OEM, potting more than 5 million filter assemblies per year with a peak exotherm under 65 °C and dimensional shrink below 0.5%.
