nes) from cast or 3D printed items, metals, wood or paper. So now we’ll take
a closer look at specific products and the
differences between them. Solvent type
adhesives can be categorized into two
groups, universal and weld type.
All of the solvent based adhesives described in this article come in sturdy glass
containers with a screw type lid with an
integrated brush applicator.

Personally, I think that Mr. Cement S
as the premiere extra thin product, which
I would recommend among these types of
excellent opportunity to assess the surface quality of the model, indispensible for
the fixup of details. I do not recommend
the use of this product on white, or light,
coloured surfaces because the adhesive
may remain visible on the surface.
MC131 – Mr. Cement SP
Another member of the extra thin family
of cements from Mr. Hobby is Mr. Cement
SP. The SP stands for ‘Super Power’. This
is a product that has the same roots as
Mr. Cement S, but with a new recipe which
yields a higher rate of drying and a correspondingly increased bond strength. It is
well suited for stressed joints where we
may want a faster bonding between parts
and a higher strength to reduce the probability of a failure. This product is ideal
for wing to fuselage joints or for leading
edges of the wings. The quicker evaporation time, though, requires the modeller
to be efficient in the process as a whole,
more so than with the use of MC129 – Mr.
MC127 – Mr. Cement Deluxe
Mr Cement Deluxe (or Mr. Cement,
the same product in a smaller packaging)
hails from the Mr. Hobby product line and
is their best for gluing together large surfaces but is still useful for small detail
items, too. It is a low viscosity liquid, meaning it flows easily and the time the solvent takes to evaporate is a little longer
than that of Extra Thin types. Mr. Cement
and Mr. Cement Deluxe (MC124/MC127)
are applied to the contact surfaces of the
components to be joined. The longer evaporation time of the solvent allows the
larger components being joined to be cantered properly. For the joining of smaller
parts, the same quality allows us to apply
small quantities of the cement to the contact surface in preparation for placing the
part in its final spot. This operation never
takes more than a couple of seconds and
the glue is ready to be applied throughout.
MC129 – Mr. Cement S
Mr. Cement S is an extra thin ‘Brush On’
type material which obviously refers to
its method of application. This involves
the joining of the two components together and running along the joint with the
solvent using the brush applicator. The
solvent evaporates very quickly from the
surface (the speed of which is comparable to acetone), but it remains within the
TECHNICAL ASPECTS OF
SOLVENT BASED ADHESIVE
The technical aspects of these types
of glues are pretty simple in and of themselves, with respect to their application.
They can be separated into two methods,
based on the type used.
Thin glues (slightly higher viscosity,
or thicker, than the extra thin variety with
a longer solvent evaporation time) require glue application to the join surface and
then attach the parts together and, if necessary, press the parts together.
Extra thin glues differ in that the parts
are first attached and the join is then
glue applied. If we aim to seal the joint
between the parts with the use of our
extra thin (such as fuselage half joining,
leading edges of wings, etc.) then there should be a small gap left between
MC 132 – Mr. Cement SP B
The last type of Mr. Hobby extra thin cement is Mr. Cement SP Black that directly comes from Mr. Cement SP. It is characterized by a very rapid drying time
and high strength between joined parts.
On top of that, it contains a black pigment
which serves as a consistency indicator
for greater application control. In recessed panel lines and joints, it can map out
crevices and scratches and provides an
