SC-100 is a water-thin, fast to medium setting cement that evaporates slower than SC-125, but faster than SC-94. This allows you to achieve a more bubble-free joint in most instances. Solvent cementing depends on the intermingling of the two surfaces to be joined so that there is actual cohesion, as in the material itself. The fewer bubbles in the joint, the higher the joint strength. Should be applied with a syringe or applicator bottle.
