-PRIMERS/PREPARATION AGENTS/SURFACE CONDITIONING/BARRIER COMPOUNDS-

Existing preformed parts often require an applied coating for prevention of leaching, softening and extraction of oils/internal substances which may cause rejection disbonding or actual decomposition of a formed part.
Zello™ and other castable soft-hard compounds are often chemically incompatible against unknown undefined species of plastics, rubber, elastoplastics, coatings, and undefined material surfaces.
Post degradement-softening and breakdown is often experienced as a slow process. Blocking barriers provide a non-diffusive chemical shield between an original part and newly introduced materials.
Depending upon the surface sensitivity existing parts may require different preparation materials such as a solvent based or waterborne conditioning agent. Pretesting is recommended. Piggyback binding of poured in place back/core fill compounds vary in chemical make up.
Vinyl plastisols typically used for toys contain a variety of unknown chemicals. A
fast drying conditioner is a wash coat prep step using Zelthane™, product code
#129. Zelthane™ is a clear solvent based stretchable/flexible lacquer or Zeltex™.
product code #278. Zeltex is a water based elastomeric film forming coating.
These two formulations are workhorse products suitable for most applications. If you plan to use hybrid back filling gels made from RTV silicone rubber/gels you will need to first apply Siltex™. product code #293. Siltex is a dear flexible/stretchable solvent based film forming lacquer which functions as a tie coat-bridging prime coat.
For additional information on primers refer to Zeller International's "U-Prime" series.
   

-RELEASE AGENTS/SEPARATORS/PARTING AGENTS-

Many castable compounds are extremely adhesive and will permanently bond to mold surfaces. Zello "HT"™ is a high tack sticky compound and is often cast into dimensional shapes and then topically post coated-dipped into liquid rubber compounds such as Cleartex™.
To prevent bonding to the mold a release agent is necessary. A range of choices exists. We recommend RTV silicone rubber compounds which provide self release clear parting without the use of a release agent.
Zeller International provides several effective parting compounds such as Zoy Lease™, product code #190,   Zoap™ product code #132, Zel Kote™ product code #130 and other formulas.
  

-FILM FORMING ELASTOMERS/SKINS/MEMBRANES-

Zello "HT"™ (215)
Zello™ (317)
Fleshtex™ (119)
Zelly Jelly™ (114)
Sil Gel™ (318)
The above five compounds are routinely poured against a preformed Cleartex™ or Zeltex™ skin for dimensional parts. The choice of film forming materials varies widely and is centered around fast setting film formulations which skin, fuse, and dry rapidly and can be layered to build up a tear resistant yet tactile skin which feels like human tissue with life like sensory perception.
Additional merits include non-yellowing durability for a long service life. Thick or thin controllable build up. Acceptance of true skin tone pigments.
Zeller International produces both water based and solvent based synthetic latex's which are allergen-protein free and do not induce rashes or anaphalatic shock.
These are single component air drying formulations.
    
Zeltex™ (278)
A remarkable 2 in 1 product. A water based, non-yellowing, odorless, single component, air drying synthetic latex compound. Dries to a crystal clear see-though coating. Super tough & tear resistive. Stretches-flexes satisfying numerous makeup applications. Used for prosthetic appliances, specialized props, banners, inflatables, balloons, & bladders. Can be internally pigmented.
ZELTEX™ is also used whenever smooth surfaces such as Plexiglas™, Formica, vinyl, metal, and wood are used for dance, aerobic, stunt, or athletic activity. For added traction, grainy fillers such as granulated cork, crumb rubber, sand, wood flour, etc. can be added. Zeltex forms an excellent film on textiles, fabrics, costumes, rain gear, tents, etc.
Zeltex™ air dries to a Shore "A" of 25 and can be made softer and more stretchy by adding Zeltex II™ at varying ratios for a softer hand.
  
Zeltex II™ (279)
A non-toxic odorless, non-ammoniated, water based, super soft, stretchy synthetic latex rubber. Used for molds, prosthetic skins, makeup appliances, toys, sculpture, novelties, props, coatings, bonding, or archival/Curatorial consolidation of fabrics, paper, and documents. Won't irritate the skin. Can be used outdoors without color loss, fading, or degradement. Zeltex II™ can be co-
blended/mixed with Zeltex™ for varying degrees of softness and flexibility. Rubbery-stretchy films-skins and coatings are easily formed.
 
Zeltex™ Thix
By adding small amounts of Thix you quickly build up a non-runny, easy to apply, thicker formulation. Thix gels Zeltex™ for viscosity control.
  
The Cleartex™ System
3 variable harness levels: soft, medium, firm. These may also be intermixed together for customized properties.
Regular Cleartex™ (117)
This is the preferred material for doll/prosthetic skins. Soft, tough, clear and durable. Cleartex™ dries fast for highly detailed parts.
Cleartex™ is a high flow liquid rubber which forms a uniform bridged membrane. Repeat pours can be built up for any desired cross section thickness from a few mils to a 1/4".
Cleartex™ can be used for dipped, brushed, slushed, or sprayed on/into molds over mandrels and forms. Both rigid or flexible moldmaking materials can be used for production processing.
Preferred mold materials are metals, ceramic. Fiberglas, RTV silicone rubber, and inert casting resins such as E.Z. Plastic™, product code #100.
Fortified gypsum cement-plaster molds will suffice providing they are fully dried and surface sealed with an epoxy finish. Aqua Form II, product code #141, is a water based polymer and is combined with water at a 50/50 ratio and combined with hydrocal, ultracal, pottery, or Venetian Plaster™, product code #326.
  

-PRIMERS/PREP AGENTS/SURFACE CONDITIONERS/BARRIER COMPOUNDS-

Existing preformed plastic-rubber parts such as vinyl plastisol materials often reject compatabilization with other dissimilar coatings-elastomers-adhesives.
Back filling with gels and dissimilar polymers often results in dissolving-melting of the vinyl part. Degradement does not occur immediately and often takes place over an extended period of time.
A shield coating barrier provides protection to the host surface. Zelthane™ lacquer, product code #129 is routinely used to coat and protect vinyl surfaces. Zelthane™ can be slushed quickly against soft or hard surfaces. Zelthane™ is allowed to dry over 24 hours. At this point you can proceed to pour in other substances such as foams, water gels, Zello™, Sil Gel™, Zelly Jelly™, Aqua Gel™, or other substances.
Depending upon your selection of a core fill substance it is advisable to conduct compatibility challenge tests.
Zeller International produces several optional preparation choices for exotic materials. Refer to the "U-Prime" series or contact Zeller International's lab for further assistance.
   

-FINISH COATINGS/LACQUERS-

Several finishing materials are available. For flexible-stretchable coatings Zelthane™ is often used.
For hard coating of polymer clay, waxes, and dense foams use Kleer Plaztik™ product code #155.
For low luster non-shiny finishes stir in matting agents are added to the finish coating material. Fumed silica powders are used at varying levels and can vary in sheen-luster reflectance by the load level introduced.
Sources-suppliers include Cabot Corp., Degussa, WR Grace Co., and others.
