ELASTOSIL® A16 BLUE
ELASTOSIL® A16 BLUE is a solventless, one component, curable elastomer designed for electronic applications. Under normal conditions ELASTOSIL® A16 BLUE has a very long skin-over time. Once ELASTOSIL® A16 BLUE is in place on the substrate, the cure is induced by exposure to a combination of carbon dioxide and moisture.
- Carbon dioxide cure acceleration
- Can be silk screened
- Excellent adhesion
Surface Preparation: The surface to be bonded should be properly prepared by cleaning with acetone, xylene, or other suitable solvent to remove all dirt and grease. The user must exercise care in selecting a cleaning solvent that is compatible with the materials to be bonded, and observe safety precautions in handling such solvents. Rubber surfaces should be lightly rubbed with sandpaper and then wiped clean with a cleaning solvent, usually acetone. The wet surface may be dried by wiping with a clean cloth or paper towel if necessary. ELASTOSIL® A16 BLUE is not recommended for use with acrylic or polycarbonate substrates.
After ELASTOSIL® A16 BLUE has been applied to the substrates, the cure may be accelerated and the adhesion enhanced by the application first of heat and then of moist CO2. Adhesion of a 5 mil coating to most substrates can be enhanced by treating for four (4) minutes at 120°F followed by four (4) minutes in a moist CO2 environment (40-50% humidity and 1-3% CO2). On particularly difficult substrates, longer oven cycles at temperatures up to 140°F may be required to develop adhesion.
