Product Description

3M™ Scotch-Weld™ 7260 B/A FC-NS is a thixotropic, two-part structural epoxy adhesive developed for high-strength, toughened bonding of metals and composite materials. It is well suited for demanding industrial environments where resistance to elevated temperatures and dynamic stresses is required.

Product Key Features

  • Toughened formulation with high peel and shear strength
  • Excellent resistance to oils, water, cleaners, diesel, and similar substances
  • 90-minute working time
  • Service temperature: -55 °C to 120 °C (tested up to 200 °C)
  • Thixotropic consistency enables accurate application on vertical surfaces without sagging
  • Cures at ambient temperature or can be accelerated at temperatures up to 65 °C

Applications

  • Structural bonding of steel, aluminium, and composite materials
  • Suitable for applications exposed to thermal cycling, vibration, or impact

Specific Gravity
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.

Work life @25°C
Work life @25°C
Work life is the amount of time we have to work with a material until it is no longer able to be easily worked and applied on a substrate.

It is based on the change in viscosity and it can rely on the application requirements.

Viscosity
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
