Poxy
Series Liquid Plastic
Description
 |
Poxy Resins (Part A) and Cure Hardeners (Part B) transform into strong plastics when the liquids are united at room temperature in the appropriate ratios. In order to provide the best system for a particular use, each resin can be transformed using various curing agents. The mix ratio for each curing agent and resin varies. To insure the best possible results, the components should be weighed precisely.
Poxy 1010 is a transparent resin utilized in combination with fast Cure 1212 for small castings such as Bonded Bronze or used with fiberglass or fillers for layup and mother molds. The resin from Cure 1220 can be used for decoupage clear coatings, glass bonding, and numerous additional uses where a nearly colorless, clear, low viscosity resin is necessary.
Poxy 1030 is an aluminum-mineral filled resin for layup or small castings with Cure 1212 and with other Cures for larger vacuum forming molds and other tooling uses. It is effortlessly machined and drilled. Application of steel wool allows it to shine to a pewter finish. Poxy 1060 is a dense, hard casting resin sold with a specially combined hardener. |
Surface
Preparation
|
Poxy supplies are adhesive and will bond to various surfaces. Wax, PVA, lacquer or other coatings may be used as a sealer to make surfaces non-porous if adhesion is not desired. Ease is then used as a release agent to coat the surface. 74 Series rubber molds require only a thin, precise coating of Ease for optimal release of epoxy castings. To ensure the surface is properly prepared, a small test cure is practical. |
Mixing
|
Poxy and Cure must be combined in recommended quantities. All mixes must be weighed with accuracy and precision except Poxy 1010 and Cure 1220, which may be mixed carefully by volume. In order to obtain the lowest viscosity and best flow, these products must be mixed well, poured, and used in as little time as possible. Time should be carefully monitored with a watch to prevent wasted materials. |
Bonded
Bronze
|
Bronze
Powder can be added to Poxy 1010 with Cure 1212 for bonded
bronze layup or casting. The mix should be at least 80% Bronze
Powder added to the previously mixed resin. For example, a
600 gram mix that is 83% Bronze is made by weighing and mixing
100 grams Poxy 1010 with 15 grams of Cure 1212 on a balance
like an Ohaus triple beam balance. Use a tongue depressor
to stir. Pour 100 grams of this mix into a clean cup (we use
paper hot cups). Then add 500 grams of tek Bronze Powder and
stir until a dense creamy mix is produced. We use cost efficient
74 Series molds sprayed with 2300 Release Agent.
This solid
may be cast in thickness up to about one inch. A more cost-effective
method is to pour it in the mold and rotate to coat all surfaces.
A disposable acid brush can be used to help coat the surface.
Special care should be taken not to scrub it through the release
because it could stick and damage the mold.
In 1 to
4 hours, the bronze face coat is leathery but not completely
hard. To fill in the casting, a low cost backing material,
such as 15-3X Urethane Resin or Poxy 1060 Resin, foam, plaster
or cement is added. The bronze face coat can also be backed
with Fiber thickened resin or a resin and fiberglass mat to
produce a hollow, sturdy, lightweight, bronze faced casting.
When cured, demold and rub surface with steel wool to reveal
highlights. Add patina with oil-base spray paint, rub off
high spots and when dry, burnish with steel wool and wax if
desired. |
Caution
|
Read
MSDS and container labels before use. Cure Hardeners and Poxy
Resins may be hazardous. Cure Hardeners may cause severe eye
and skin burns. Contact may result in injury to skin and/or
allergic dermatitis after prolonged or repeated contact. All
contact with the skin and eyes should be avoided. Use adequate
ventilation to prevent inhalation of vapors. If skin contact
occurs, wipe off and wash immediately with soap and water. In
case of eye contact, flush eyes with plenty of water for at
least 15 minutes and seek medical attention.
|
Cleanup
|
Paper towels may be used in order to remove mixed or unmixed resin and hardener. Tools should be wiped clean before the material hardens. Lacquer thinner, acetone and toluene are good cleaning although they are highly flammable. Use Ease to wax or coat work surfaces so hardened material can be removed effortlessly. Waterless hand cleaner and grit soaps are best for removal from hands. Chipping, scraping or heating is often necessary to remove cured resin. |
Cure
Blends
|
Epoxy
resins cured with Cure 1212 cure fast and hot in masses to
very hard, heat resistant castings. Cure 1230 produces long
working time, slow cures, and resilient castings. Thus, large
masses can be cast without extreme heat buildup. A blend of
these two cures produces useful combinations of features.
For instance, Cure 1260, shown for Poxy 1060 above, is 8%
Cure 1212 which is used at 4.2 Parts per 100 (PHR) and 92%
Cure 1230 which is used at 11.4 PHR.

These calculations are only for Poxy 1060.
Please note different ratios are needed for Poxy 1030. If
you wish to blend hardeners for other resins, please call
for PHR of each cure needed for that specific resin.
It is important to be accurate in your calculations
and weighing of components when blending Epoxy Cures. |
