Jesmonite
is a casting and laminating system that provides a safe to
use alternative to polyester and fibreglass resin systems.
it is externally durable ,flame proof, dimensionally stable
in large parts, and easy to pigment.
AC100
is the most comonly used material for casting laminating colouring
and filling with metal powders.
AC200
soft carving composite ,often used to coat polystyrene carved
into then painted with ac100 to make durable
AC720
high external durability, cement based composite.can be coloured
but not filled.
AC730
high external durability , in four different stone finishes,
white marble sandstone silver grey granite and portland stone.
Also
available for more specialist applications are AC 300, AC400,AC700
Jesmonite
is extremely versatile and has been used in many different
industries please contact

AC 100 Users' Guide
Mixing:
Jesmonite
is a mixture of powder and liquid and can be mixed at a max
of 3 powders : 1 liquid and a minimum of 2 powders : 1 liquid,
to acheive different working properties
and viscosities. Most economically mixed at 3:1. mix the two
components together using a high shear blade in an electric
drill at around 1000rpm. mix until there are no lumps , don't
over mix as you may entrap some air bubbbles.
PIGMENT
The pigments are added to the liquids and should be thoroughly
dispersed by slow speed use of the high shear mixer prior
to adding the powder.
All the pigments are intermixable to enable any colour to
be achieved, different tones are achieved by quantity.
It is recommended not to exceed 2% (20 9 per kg) of total
mix.
Thixotrope
When working into a multi piece mould or when laminating it
may be necessary to thicken the material to gel coat consistency.
Thixotrope should be added to the material after mixing and
will allow the user to put down a 2-3mm layer in one pass.
It should be added drop by drop to the mix using the high
shear mixer until the desired consistency is achieved. N ote:
the thickener is very reactive and as such should be added
slowly. typically between 1g and 4g per kilo of total mix.
Laminating
After applying the gel coat it is possible to create a laminated
structure. Quadaxial glass fabric is used for the reinforcement
of laminated structures. It is only necessary to use two layers
of the fabric.
Firstly 'wet out' the back of the gel coat using unthickened
material and apply the first layer of glass fabric reinforcement.
Then 'wet out' the first layer thoroughly to ensure complete
incorporation of the reinforcement.
The other layer of fabric is spaced by a layer of Jesmonite
AC 100 mixed with 6mm c~opped glass strand to create a 'slurry'.
Apply a 2-3mm layer of this chopped strand mlx. Apply the
second layer of fabric and 'wet out' to complete the lamination.
This will result in a 'sandwich-like' composite structure
for use as a panel or a mould case for example. By increasing
the thickness of the spacing mix a stiffer laminate will be
constructed.
Stone fillers
Stone finishes using Jesmonite AC 100 can be achieved by the
use of special fillers. Four stone fillers are available in
the following colours:
1) Yellow Sandstone 2) White Marble
3) Silver Grey Granite 4) Portland Stone
Metal fillers
Metal finishes using Jesmonite AC 100 can be achieved by the
use of special fillers. Four metal fillers are available in
the following colours:
1) Bronze 2) Brass
3) Copper
4) Stainless Steel Flake
Note: Antique black powder is also available to darken metal
finishes.
Mixing with fillers:
Mix the Jesmonite AC 100 powders and liquids at a 2.5: 1 ratio
as described in sections 1 and 2 above. It is possible to
add metal fillers at an addition rate of 70% -100% by weight
to the mixed Jesmonite AC 100. Antique black powder can be
added to both the bronze and copper to achieve a richer tone
at an addition rate 2g and 5g per kg. The antique black powder
should be added to the metal filler prior to addition to the
AC 100 mix.
This mix can be used as a casting compound or as a gel coat
for a Jesmonite AC 100 laminate. Upon demould the product
should be left in a warm dry environment for a minimum of
24 hours. It is now possible to expose the metal filler by
gentle abrasion with fine grade wire wool. N. B. Stainless
steel does not require abrasion.
After exposing the metal filler is is possible to patinate/oxidise
the surface to achieve a 'verdigris' effect. It is also possible
to polish the metal surface using, for example, Colron furniture
wax.
Sealer
Jesmonite Sealer has a variety of uses. If used neat on the
surface of Jesmonite products it will result in a satin finish
which gives maximum protection for external use. Two coats
are recommended. For internal use, to stop finger marks and
achieve a more matt finish, Jesmonite Sealer can be let down
with water by 90%. By adding pigments to the watered down
mix described above it is possible to create colour washes
for patination. This is an artistic effect and as such experimentation
should be carried out. It is also possible to create metal
top coats for use on Jesmonite products. These can be spray
applied using a gravity fed air-mix spray gun fitted with
a 1.7mm tip, or stippled on using an appropriate brush.
Bronze, copper and brass should be added to the sealer at
a ratio of 2: 1 by weight. Abrasion of the dried surface should
be carried out as described in section 8 above. N. B . Stainless
steel should be added to the sealer at a ratio of 1:4 by weight
(stainless steel to sealer). As before it does not require
abrasion but can be polished when dry.
retarder
this can
be added to weighed liquids to extend pot life. typically
between 2g and 6g per kilo of total mix. max pot life about
35mins.
