SILASTIC 3112

Main features

  • 28,000 cP Base Viscosity
  • Adjustable Catalyst-Controlled Cure
  • Simple-Pattern Mold Making

Product Description

SILASTIC RTV-3112 Mold-Making Base is a white, general-purpose condensation-cure silicone base for producing simple molds without deep undercuts. The base has a typical viscosity of 280 poise (28,000 cP) and a specific gravity of 1.30 at 25 deg C, supporting pourable processing and reproduction of detailed patterns. A compatible catalyst is selected and added separately to establish the working and cure profile; the base is not a complete mold-making system by itself. Use is limited to mold geometries, catalyst ratios, release practices, and cure conditions validated for the intended pattern and casting material.

Key features

  • 28,000 cP base viscosity: Supports pourable mold preparation at 25 deg C
  • Separate catalyst control: Catalyst selection and ratio establish the working and cure profile
  • Detailed pattern reproduction: Low mixed viscosity supports replication of intricate features

Applications

General-purpose silicone mold making for simple patterns without deep undercuts, using a compatible catalyst and validated release and cure process.

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Physical Properties
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application

Mechanical Properties
Elongation
Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
