ADHESIVE  FOR  SURFACE  MOUNTED  COMPONENTS

WK-1661

GENERAL  DESCREPTION：

This is fast curing, one component with excellent Shelf-Life Stability.It is particularly suited for used on the high quality electrical industry.Such as

Ferrite Core,C.O.b………..etc.

STORAGE  INSTURCTIONS:

Refrigeration of uncured compound is required to maintain viscosity.If slight separation occurs,stir gently until product is uniform,after allowing unopened

container to reach room temperature.
