LOCTITE SI 5056

Main features

  • 1,400 to 3,000 mPa s Viscosity
  • At Least 4 mm Depth in 60 Seconds
  • 22.8 kV/mm Dielectric Strength

Product Description

LOCTITE SI 5056 is a one-part, low-viscosity alkoxy silicone adhesive that cures with UV or visible light for bonding, potting, coating, and sealing. As supplied, viscosity is 1,400 to 3,000 mPa s at 25 deg C by Brookfield RVT. At 70 mW/cm^2 and 365 nm, tack-free time is up to 30 seconds with the Zeta 7215 light source, while depth of cure reaches at least 4 mm after 60 seconds with the Zeta 7200 light source. Full performance properties develop over 72 hours, and cured dielectric breakdown strength is 22.8 kV/mm by IEC 60243-1.

Key features

  • 1,400 to 3,000 mPa s Viscosity: Brookfield RVT at 25 deg C, spindle 3, 20 rpm.
  • At Least 4 mm Depth in 60 Seconds: Measured at 70 mW/cm^2 and 365 nm using a Zeta 7200 light source.
  • 22.8 kV/mm Dielectric Strength: Measured by IEC 60243-1 after 60 seconds per side at 70 mW/cm^2 and 365 nm, followed by 24 hours at 22 deg C and 50 +/- 5% relative humidity.

Applications

Bonding, potting, coating, and sealing.

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.
