Main features

  • Rubber-to-Wood Epoxy Bonding
  • 2-Hour Working Window
  • 30.4 MPa Aluminum Lap Shear

Product Description

ARALDITE® 2011-A/B is a two-component, multi-purpose epoxy adhesive for bonding metals, ceramics, wood, vulcanized rubber, foams and plastics. The viscous system mixes at 100:80 by weight or 1:1 by volume and provides a typical 2-hour pot life at 25°C for a 4 fl oz mass. It can be applied manually or with meter/mix equipment and cures from 20°C to 180°C without releasing volatile constituents. The cured adhesive is electrically insulating and combines shear and peel performance with resistance to static and dynamic loading. Recommended bondline thickness is 0.05 to 0.10 mm, with handling strength achievable from 12 hours at 20°C to 4 minutes at 150°C under the stated cure schedules.

Key features

  • Broad substrate range: Listed for bonding metals, ceramics, wood, vulcanized rubber, foams and plastics.
  • Extended working time and flexible cure: Typical pot life is 2 hours at 25°C for a 4 fl oz mass, with room-temperature and accelerated heat-cure schedules.
  • Documented bonded-joint performance: Typical aluminum lap shear reaches 30.4 MPa after a 150°C cure for 10-20 minutes, with roller peel of 4.9 N/mm under the stated test conditions.

Applications / Suitable for

  • Metal bonding
  • Ceramic bonding

Technical Specifications

General Properties
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.

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.

Thermal Properties
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding. The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
