Polyurethane RTV Mold Rubber
The 74-30 is the softest of our RTV rubbers. These rubbers can be used for making
durable, easy releasing molds for casting gypsum plasters, waxes, cement, epoxy resins
polyester resins along with urethane and acrylic. Proper
mold release is needed to
insure easy parting from the mold.

74-30 RTV Liquid Urethane
Mold Rubber
Mixed 1 Part A to 1 Part B
Working Time: 30 Minutes
Demold Time: 24 Hours
Hardeness, Shore A: 30

Info: Our softest polyurethane. Fairly soft and stretchable. Good for molds with complex shapes or detail that might require an easily flexible rubber.

Mold Release Info: For releasing this rubber from a smooth non-porous original/plug an aerosol such as Poly-2300 or Stoner is suitable. Porous objects such as plaster, concrete or wood should first be sealed to create a smooth surface from which to apply the mold release.

Polygel 40
Self Thickening RTV Liquid Urethane Rubber For Brush-On Molds
Polygel mold rubbers consist of two liquids, Part A and Part B which after mixing immediately gel to a brushable or trowellable consistency, then cure overnight at room temperature to a flexible, tough RTV rubber. They are ideal for molds built up with a brush, spatula or spray, Polygel mold rubbers are recommended for evaluation as a mold material for plaster, cement and waxes, as well as for limited casting with polyester epoxy and polyurethane resins.

Poly Gel 40
Mixed 1 Part A to 1 Part B
Hardness, Shore A: 40

Info: A self-thickening brushable mold rubber. Used primarily for blanket molds. Usually requires a mother mold backing to support the mold after it is made. Plaster or fiberglass and resin are commonly used for mother molds.

TinSil 70 Series RTV Silicone Mold Rubbers
Consists of a liquid Part B base and Part A accelerator which after mixing at the proper ratio by weight, cure at room temperature to a flexible high tear strength RTV silicone rubber. All TinSil 70 Series mold rubbers are tin-catalyzed, condensation-cure systems. They are ideal for molds where easy release or high temperature resistance is needed. They are recommended for evaluation as mold materials for polyester, epoxy and polyurethane resins and waxes. Mold release is not required for casting parts in silicone molds. A mold release wax may be needed when pouring the liquid silicone rubber onto a porous substrate such as wood or plaster. Should not be used with silicone based releases or lubricants.
70-25 Tin-Sil
RTV Silicone Mold Rubber

Mixed 10 parts B to 1 part A
Hardness, Shore A: 25
Pour Time: 60 min.
Demold Time: 24 Hours
