  • Heat-Resistant Bonding Service
  • 1:1 Controlled Mixing

Product Description

ARALDITE® AV 8503 Resin / Hardener HV 8503 is a two-component epoxy adhesive paste developed for bonding sheet molding compound, plastics, and metals. The blue resin and beige hardener mix at a convenient 1:1 ratio by volume and form a non-sag paste with approximately 100 minutes of pot life at 25°C. The adhesive combines good flexibility with heat resistance and can achieve rapid handling strength using a heated fixture. Its surface-preparation requirements are limited to a dry wipe before bonding, supporting straightforward assembly processes where controlled paste application and accelerated heat cure are required.

Key features

  • Rapid heat fixture: Reaches fixture strength in approximately one minute on a fixture heated to 116°C.
  • Flexible cured epoxy: Provides 15% elongation with a Shore D hardness of 78.
  • Convenient paste mixing: Uses a 1:1 mix ratio by volume with good weldability and non-sag application behavior.

Applications / Suitable for

  • Sheet molding compound bonding
  • Plastic assembly
  • Metal bonding

Pot Life
Pot life is the amount of time it takes for the viscosity of a material to double (or quadruple for lower viscosity materials) in room temperature after a material is mixed. It is closely related to work life but it is not application dependent, less precise and more of a general indication of how fast a system is going to cure.

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.

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.

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.
