Directions for Use

1. For high strength structural bonds, paint, oxide films, oils, dust, mold release agents

and all other surface contaminants must be completely removed. However, the

amount of surface preparation directly depends on the required bond strength and

the environmental aging resistance desired by user. For suggested surface

preparations of common substrates, see the following section on surface preparation.

2. These products consist of two parts. Mix thoroughly by weight or volume in the

proportions specified on the product label and in the uncured properties section.

Mix approximately 15 seconds after a uniform color is obtained.
