Flexible Gel Molding / Casting Compounds

The Insta-Gel® and Insta-Gel® Spray product lines offer a self-thickening gel feature. After mixing the liquid Component A and B the mixture thickens to a creamy buttery like consistency that allows for the application of polymer on vertical or uneven surfaces. The cured polymers form a tough and durable rubber liner that can be used for casting concrete and plaster parts.

Flexible Gel Molding / Casting Compounds

Insta-Gel® products are designed for “hand mixing” giving 15 to 20 minutes applications times.

Insta-Gel® Spray products are designed for high volume rapid set applications and require plural component spray equipment.

Before applying Insta-Gel®, surfaces should be coated with silicone or wax mold release and must be free of moisture to prevent unwanted bonding or surface bubbling. Mold releasing agents must be used to ensure easy removal of Insta-Gel® rubber mold from the master.

These products feature:

  • High viscosity
  • Flexible molds
  • Mechanical durability
  • High tear resistance
  • Easily hand mixed (Insta-Gel®) or machine dispensed (Insta-Gel® Spray) with a small handheld dual cartridge spray gun or electric gear driven 2 component plural spray machine where high volume production is required.

 

Applications and Uses

  • Casting of concrete and plaster parts
  • Molding wax for bronze sculpturing
  • 3-dimensional objects
  • Vertical wall surfaces
  • High detail castings
  • Architectural theming
  • Animatronics
  • Natural texture reproduction
  • Special effects applications
  • Molds from wood, plaster or clay masters (mold release agents should be applied to master before coating)

 

Specific Applications

 

 

 

 

Flexible Rubber Molds

Very soft and flexible rubber used to create molds that require high elongation to release parts that are deeply uncut.

Available in a brush-on and spray-on molding formulation.

Best Products for Flexible Rubber Molds

Insta-Gel 20 & Insta-Gel Spray 20

Product Features:
  • High Elongation
  • 20-30 Shore A Hardness
Product Uses:
  • Casting of concrete and plaster parts
  • Molding wax for bronze sculpturing

 

 

Brush-On Molding / Casting Gels

Brush-On Molding / Casting GelsTwo-component urethane elastomer that is specifically formulated as a brush on molding compound. After mixing, Insta-Gel thickens to creamy butterable gel that can easily be brushed on to vertical or overhead surfaces without sagging or running. In 24-hours Insta-Gel cures to a tough rubber mold and is ready for use. These products are tough and has a high tear resistance as well as good grease and oil resistance. They have long mold storage life, insensitive inhibition and good adhesion between coats, as well as color coded for better mixing indication.

Spray On Molding Gels

Insta-Gel Spray is urethane which becomes very thick after part A and B components are mixed together. Having a urethane product which is very high in viscosity (a paste consistency) allows the product to be applied very thick on a surface without sagging or running down. Spray on rubber mold making rubbers are very help and time saving when you are making rubber molds from large 3-dimensional masters. A spray on rubber is also helpful if you want to spray into an open-faced mold to make a large flexible rubber skin for animatronics applications.

Product Features:
  • High viscosity (a paste consistency)
  • Provides for a tough, flexible stand-alone mold that does not requirement containment boxes
Product Uses:
  • Rubber molds from large 3D masters
  • Open-faced mold to make a large flexible rubber skin for animatronics applications
  • Architectural, fine art or natural texture reproduction
