MC132 Mr. CEMENT SP Black is a black colored Mr. CEMENT SP, so it has a fast drying speed and high adhesive strength. This is a "BRUSH ON" type cement, so you must put together the plastic parts first, and then brush on the cement on the gap between the parts. With this black colored cement, you can easily check to see how much cement is applied and if it has been applied evenly. Not recommended to apply on white or light colored plastic surfaces because the cement will be visible. Use clear colored MC131 instead.
