Known to experienced model makers as EMA Plasweld, this solvent sticks all normal model making plastics, i.e. perspex, ABS, butyrate, styrene, acrylic etc. It has a long shelf life, is fast acting (grabs in seconds), and has a water-like consistency so it is best used by holding or clamping the surfaces together and running a loaded brush or applicator along the length of the joint (solvent will be drawn into the joint by capillary action). A second application can be made if required, but is not normally necessary. When joining dissimilar plastics, i.e. styrene to butyrate, the hardest material (in this case butyrate) should have the joint surface softened, by giving a light coat of solvent, prior to holding the surfaces together. Then proceed as normal. Plastic weld cement should be used in a well ventilated area and contact with skin or eyes should be avoided (wash well with water if this occurs)
