DOWSIL 7094

Harmonization Code : 8001.20 | Unwrought tin: Tin alloys

DOWSIL 7094

Main features

  • Self-Leveling Flowable Placement
  • 400% Cured Elongation
  • 25-Minute Skin-Over Time

Product Description

DOWSIL 7094 Flowable Sealant flows and self-levels into gaps where a one-part, neutral-cure silicone sealant is required for sealing or bonding. The black or white viscous liquid has a typical density of 1.30 g/cm^3 and viscosity of 28,000 mPa s, allowing flow into gaps and airless-spray application. At 23 deg C and 50% relative humidity, it skins in about 25 minutes, becomes tack-free in about 50 minutes and cures inward from the exposed surface. After seven days under those conditions, the sealant has Shore A 19 hardness, 400% elongation and 1.2 MPa tensile strength.

Key features

  • Flowable self-leveling rheology: Typical viscosity is 28,000 mPa s for gap filling and spray application.
  • 25-minute skin-over time: Supports tooling and assembly before surface cure.
  • Flexible cured seal: Typical elongation is 400% with Shore A 19 hardness.

Applications

Sealing and bonding applications requiring a low-viscosity, self-leveling silicone sealant.

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.
