Introduction
Darbond 11021 is a two-component, room temperature curing
Epoxy adhesive. The product is a cold welding repairing
Material filled with steel powder and ceramic, easyto use with
Wide application; No-sagging after mixed. After cured, it has
Good properties of high bonding strength to substrate, impact
And corrosion resistance and can be machined.

Typical Applications
Good bonding performance to metal, ceramic, concrete and
Some plastic; Suitable for defect and wear repair of steel, iron
Casting and machined part; Widely used for manufacture and
Maintenance of shipping, port machinery, automotive and
Mining machinery etc.

Directions for Use
Cleaning and Preparation: Make repair surface coarse by Grinding. Remove oil and grease from the surface. It is Recommended to use Darbond high efficiency cleaner 2755 For best effect.
Mixing: As per usage amount, mix A and B component Thoroughly by ratio to make the mixture color uniform.
Dispensing: Dispense the mixture to prepared surface with Trowel, make it compact, eliminate gaps and air bubbles, Moulding and even.
Curing: Cure according to min. Curing time at room Temperature before operation. For faster curing conditions, Heat up properly.
Note: The higher temperature and the more mixture, the Shorter pot life; Conversely, the longer port life. In case of Low temperature below 10, it is recommended to preheat Repairing surface; In case of high temperature, reduce Mixture quantity.

Cautions
Keep out of reach of children.
It is recommended to use at well ventilated place.
In case of contact with skin, wipe away, then rinse with Clean water; In case of contact with eyes, rinse with clean Water immediately; If symptom goes on, call a physical Attention.
