3M Scotchcast Resin 5

Surface Preparation

For best results all surfaces to be bonded should be dry and free from dirt, dust, oil, loose paint, wax, grease, etc. Oil, grease and other contaminants can be removed by wiping with a solvent such as methyl ethyl ketone. If used for decorative laminate, laminate should have reached moisture equilibrium for the shop conditions.

Application

The temperature of the adhesive and surfaces to be bonded should be at 65°F (18°C) or above. Warm the can of adhesive by placing in a warm room, not in stove, oven or other possible ignition source. If the room must be warmed, turn off the heater before opening container. Leave heater off until all vapors are gone. Stir thoroughly before using. Apply adhesive generously in a uniform film on both surfaces with either a fiber or animal hair brush, or pour and spread with paint roller (solvent resistant texturing type). Porous surfaces may require 2 coats of adhesive. A glossy film when completely dry indicates adequate adhesive. Dull spots after drying indicate not enough adhesive.

These spots must have another coat.

Curing

Allow to dry until adhesive is no longer tacky (5-10 minutes). Position surfaces carefully before assembly. No adjustment is possible after contact. Spacers such as dowels or strips of laminate, may be used to prevent premature adhesive/adhesive contact and bonding. Slide out the spacers and apply uniform pressure, working toward the edges. A 3 in. roller used with maximum body pressure should be used to help ensure adequate contact and bonding, especially on the edges. Bonded assemblies can be machined, trimmed or finished immediately after bonding. Drying time depends on temperature, humidity, air movement and porosity of materials bonded.

Clean-Up

Excess adhesive may be removed with a solvent such as methyl ethyl ketone.*

*When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturer’s precautions and directions for use.
