Craftics Plasticators and Syringes are the choice for bonding Acrylics and plastics using the capillary method. For best results, assemble parts to be glued in their final position, then use the applicator to apply a thin line of solvent cement along the edge where the parts meet. The cement will run into the joint and bond evenly and invisibly.
The oval squeeze bottle is the most popular tool for applying solvent cement. Simply squeeze some air out of the partially filled bottle before inverting to avoid drips, and you’ll have an even, controlled flow. Plasticators are designed for easy needle replacement in case of clogging.
