Latex
60 is a one-part, brush-on liquid often used for casting plaster,
concrete and limited casting with some resins. It can be built
up from 1/16th inch to 1/8th inch thick, when multiple coats
are applied with time to dry between each coat, to form a
tough rubber blanket mold.
Latex
60 has superior tear strength compared to synthetic rubbers
and may be favored for molds that peel off the casting. Two-part
synthetic rubbers like Gel 40 and 50 can be brushed-on to
final thickness in an afternoon and should be considered for
molds wherever latex is used.
