Viscous Cementing Acrylic
Sheet Use viscous cements to join parts that can't be
easily cemented by the capillary or soak solvent methods-either
because the joints are hard to reach or because the edges don't
fit together well. Viscous cement is thick. It will fill small
gaps and make strong, transparent joints where solvent
cements can't. Viscous cements are available from CHEMCAST®
GP sheet distributors. Or, make your own viscous cement by
dissolving chips of clear CHEMCAST® GP acrylic sheet in a small
amount of solvent. Let the solution stand overnight in a
tightlycovered container. Remove the masking from around the joint area
and carefully apply a bead of cement to one side of the joint
using a brush, spatula, or the cement applicator. Then gently
join the pieces together as described under 'soak cementing.' A solventresistant tape (Riveter's tape from
3M Co.) may be applied to protect the area around the joint but
it sohuld be removed carefully after about five minutes, while
the cement is still wet. Don't touch the parts at all for the
critical first three minutes, or the joint will not hold. The
part may be carefully moved after ten minutes. |
