WINKING  EPOXY  ADHESION  SYSTEM

WK-1401

GENERAL DESCRIPTION：
This is an one component, hot curing system, rigid epoxy adhesive and insulation for blob top.It is sutitable for the high quality electrial industry. The material can be mix with solvent to lower the viscosity.
 
STORAGE  INSTRUCTIONS
  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.
