USES:
Poly 15 Series liquid plastics are useful for production of
decorative objects, parts, lightweight mold shells, tools,
models, patterns, fixtures, duplicate masters, vacuum forming
molds and general tooling use. Poly 15-6, 1510, 1512 and 1512X
have the feel and density of wood or thermoplastics and Poly
15-3 and 15-3X are more like stone.Poly 15-8 is an aluminum-filled
system for high heat-resistance applications such as vacuum
forming where good thermal conductivity is required. Poly
1512 Clear is useful for casting transparent parts or for
pigmenting/color casting. Poly 1512 Clear may be used for
cold cast bronze or other applications utilizing dry fillers.
1512 Clear will yellow with age. For applications requiring
water-clear, non-yellowing plastics, see the Poly-Optic®
products.
MOLD PREPARATION: These products reproduce
minute detail from a mold or pattern, but may stick or foam
when poured on improperly prepared surfaces. A trial casting
on a surface finish similar to the final mold should be made,
to avoid damaging a valuable mold. Polyethylene and silicone
rubber molds, such as TinSil® and PlatSil® systems,
do not require a release agent, but a barrier coat may be
helpful. Latex, polyurethane rubber or metal molds must be
dry and require a coat of a suitable release agent, such as
Pol-Ease® 2300. The Poly 74 Series are well suited for
limited casting in Poly 15 Series products.
ADDITIVES: Part X is a powerful catalyst
to increase the speed of curing. A few drops in a one pound
mix speeds the cure significantly. Exotherm (heat of reaction)
and thus shrinkage on cooling is increased. Experiment to
determine the right amount of Part X to use, but never use
more than 1% Part X of the total weight of the mix or the
final physical properties may be affected. Poly 15-3X and
1512X already have Part X added. Part F can be added to mixed
Poly 15-6 and 1510, (up to 3%) to create foams with densities
as low as 6 lbs. per cubic foot. Poly Fiber can be added to
thicken the mix to a paste consistency. Microballoons can
be added to create a wood-like, lower density material. See
Poly LiteCast.

MIXING: Prior to mixing, all molds and equipment
must be prepared. Parts A and B should be above 60oF.
Parts A and B should each be stirred thoroughly prior to use.
Over a period of time, sediment may develop on the container
bottom. Normally, gentle mixing to disperse the sediment prior
to use is all that is required. Once the containers of Parts
A and B are opened, they should be used or resealed tightly
as atmospheric moisture contamination may cause foaming of
the plastic. Metal or plastic mixing vessels and spatulas
should be used to avoid introducing moisture as may happen
with paper or wood tools. Measure or weigh Parts A and B into
a mixing container. Polyethylene buckets are excellent and
can often be reused. Once components are weighed, add Part
X or Part F, if desired. Mix immediately, thoroughly scraping
sides and bottom for one minute. Pour mix into cavity as quickly
as possible. If desired, Cab-O-Sil® or Poly Fiber should
be added after Part A and B are mixed.
CURING:
Castings should be allowed to remain in the mold until thoroughly
cured. Parts demolded too soon may be subject to deformation.
Use of pre-warmed molds will hasten curing. Low temperatures
will slow the cure and extend demold time.
FINISHING:
Cured Poly 15 Series plastics will yellow and chalk when exposed
to sunlight and should be painted for exterior use. They can
be easily drilled, sanded and machined. If they are to be
painted or coated, adhesion of the coating should be checked
carefully over a period of time to determine that it is satisfactory
for the intended use. If all mold release is removed by detergent
and/or solvent washing, most oil paints work well.
CLEAN
UP: Tools should be scraped clean before the plastic
is hard. Alcohol (shellac thinner), acetone or MEK are good
cleaning solvents, but are highly flammable. Work surfaces
can be waxed or coated with Pol-Ease® 2300 Release Agent
so hardened resin can be removed.
STORAGE
LIFE: At least six months in unopened containers
at room temperature (60-90oF).
WARNING:
See Methods of Use.
Poly Plastics burn readily when ignited. Care should be taken
with sanding dust and other easily ignitable forms of these
products.

PHYSICAL PROPERTIES
& PACKAGING
PART
F FOAMER - Liquid additive for foaming Poly 15
Series resins.
Purpose: Addition of up to 3 parts Part F per 100 parts mixed
Poly 15 resin will result in foaming while the mix is curing.
With Poly 15-6, foams with densities as low as six pounds
per cubic foot can be created.
Foams created with Part F are useful for filling spaces with
less resin than would be required if poured solid. These foams
do not have skins suitable for finished objects and are suggested
for filling slush castings of Poly 15 resins. The more Part
F used, the less dense the foam will be and the higher it
will rise. Too much Part F will result in foam collapse. Experimentation
will be necessary to determine how much Part F should be used
for each application.
Foams created with Part F have fairly good flow before the
mix gels, but if the rising foam is forced to flow too much,
foam collapse can occur. Rising foam can exert significant
pressure if confined, so care should be taken that it does
not distort or crack parts being filled.
TOP
MIXING:
Shake Part F well prior to each use. Do not use any other
additives with Part F. Weigh the required amount of Part F
and mix into the Part B, then add the Part A and stir for
one minute. Immediately pour into the cavity to be filled
and allow to rise and harden without disturbing.
CAUTION:
Part F is an alkaline liquid which can cause burns to
skin and eyes. Avoid skin and eye contact. Should contact
occur, flush eyes with water for fifteen minutes and see a
physician. Remove from skin with soap and water.
CUSTOM
FORMULATIONS
Creative polyurethane chemistry
allows an infinite variety of resins and rubbers to be produced,
from hard dense plastics to limp, dead soft rubbers with cure
times from many hours to a few minutes. If you have a need
for quantities of such a custom formulation, please give us
a call.
