SUGGESTED METHODS OF APPLICATION & BONDING
APPLICATION
Brush or roller, plastic squeeze bottle, flow gun and mechanical roller coater.
SURFACE PREPARATION
Insure that all materials to be bonded are free of dirt, dust & oils. If necessary use
M.E.K. or other suitable industrial-solvents for cleaning.
BONDING METHODS
Method 1: If one of the surfaces to be bonded is porous apply C252 to one surface,
clamp for 2 - 3 hours.
Method 2: Modified Contact - Apply C252 to both surfaces and allow solvent to
volatilize for 1 - 2 minutes, then combine, press or roll using as much
pressure as is practical.
Method 3: Heat Activation: Apply C252 to both surfaces & allow to dry (at least 20
minutes) then heat the surface to 65 - 75 C.. Combine hot & tacky
surfaces, press or roll with as much pressure as is practical.
Method 4: Solvent Activated Assembly: Apply one or two coats of adhesive to each
bonding surface. Allow at least ten minutes drying time between coats
after the final coat. Brush or swab activating solvent over one or
preferably both surfaces and position and assemble using firm hand
roller pressure within 90 seconds.
CAUTIONS
RAINBOW C252 contains flammable solvents. Use some precautions as when
handling gasoline. Adequate ventilation must be provided in working areas. Keep
containers tightly closed when not in use. Store at room temperature ( 23 C.).
