Potential Uses

N/A
Supplied at a higher viscosity, this material cures to a tough, durable elastomer for improved pin/solder joint coverage and thin-section encapsulation.

Application Methods

N/A
Applied by brush or flow coating or syringe dispensed for spot protection of pins or other devices.

Cure

N/A
Time to cure is dependent on several variables including the method of application, film thickness, temperature and humidity. Tack- free time in the data table gives an indication of typical times until surface is dry enough to handle. Cure time for full cure are indications of time needed to develop full physical properties such as durometer, tensile strength or adhesion. These times, including full cure time, can be significantly improved by introducing mild heat of 60 °C or less.
