General Description
SpiderAdhesive EST-CL30 is a two component 2:1,colorless to slight yellowish, low viscosity, industrial grade, epoxy structural adhesive.
Once mixed, the two component epoxy cures at room temperature with minimal shrinkage to form an ultra clear adhesive bondline with excellent impact resistance.
The fully cured epoxy is resistant to a wide range of chemicals and solvents and has excellent dimensional stability over a wide temperature range.
Typical applications
Typical applications include bonding, small potting, staking and laminating applications where optical clarity and excellent structural, mechanical and electrical insulating properties are required. It bonds most materials including glass, optical fibers, ceramics, metals, and many rigid plastics.
