3M 2086

Application

EC-2086 can be applied by a spatula, knife coat, notched trowel, or by extruding into place. Standard equipment is available which allows pumping directly from five-gallon pails.

Curing

The only pressure needed during the cure of EC-2086 is that required to keep parts in alignment and to overcome distortion and thermal expansion in the adherends.

The cure temperature may be varied from 330°F to 500°F (165°C to 260°C), depending on the materials being bonded, equipment available and bond properties desired. EC-2086 will wet the surface to which it has been applied. Heating at temperatures above 325°F (163°C) will chemically convert the adhesive into a high strength solvent-resistant bond.

Cure time depends on the cure temperatures used, methods of heat application, production limitations and bond properties required. Since no two bonding operations are exactly alike, it is suggested that a few simple experiments be conducted, varying both temperature and cure time to determine optimum conditions for the particular application. Figure 1 is a guide from which an approximate cure cycle can be taken for various cure times or temperatures.

Clean-Up

Excess adhesive and equipment may be cleaned up, prior to curing, with Ketone type solvents.*

*Note: When using solvents, extinguish all ignition sources and follow the manufacturer’s precautions and directions for use.
