Different solvents can be mixed to produce a mixture with optimal properties.
For instance, if two dissimilar materials are to be joined, a mixture of two
miscible solvents specific to the different polymers can be used. A mixture of
methylene chloride and ethylene dichloride is sometimes used for Xantar
polycarbonate and polycarbonate blends. Methylene chloride evaporates faster
than ethylene dichloride. A longer assembly time is therefore required if
ethylene dichloride has been added.
A slurry made of solvent and up to 25% of the base resin can be used to
produce a smooth filled joint when the mating parts do not fit perfectly.
Adding base resin makes the solvent easier to use.
It is important to consult the Material Safety Data Sheet of the solvent used,
for health and safety information and for proper handling and protection
equipment.
