20-2521 is a high performance two component urethane system. This easy to use polyurethane is very low in viscosity and ideal for potting or encapsulating delicate electronic components. 20-2521 exhibits very low shrinkage, stress, and exotherm throughout the cure cycle. This system is also well known for its outstanding thermal shock and excellent dielectric properties.

20-2521 is ideal for potting applications where a wide operating temperature (-55 to +130°C) is required. It is also a good choice when exposure to salt water, mild acids and bases, and aliphatic hydrocarbons is expected.
