ER1448 Specialist Radio Frequency Encapsulant

In Stock

ER1448 is a specialist resin system formulated primarily for encapsulating radio frequency transmitters in applications for the automotive and aerospace sensor markets but can perform well in a wide range of harsh operating conditions making it suitable for industrial and marine applications. It exhibits good thermal cycling properties offering stability in applications with large temperature variations. While its low viscosity and fast curing system makes it an ideal choice for high throughput applications, and where complex geometries are involved.

ER1448 offers excellent adhesion to a wide variety of substrates and exhibits high water resistance.
