  • 475% Elongation with 100 Pli Peel

Product Description

ARALDITE® AY 8683 Resin / Hardener HY 8683 is a two-component polyurea elastomeric adhesive formulated for filter-bonding applications. The fast-setting system cures at room temperature and can be mixed by hand or processed through meter-mix equipment. A 100:60 resin-to-hardener ratio by weight or volume, 15-minute pot life at 77°F (25°C) for a 90 g mass, and typical mixed viscosity of 2,500–3,000 cP support dispensing and assembly. After a seven-day room-temperature cure, typical properties include Shore A 95 ± 5 hardness, 475% ultimate elongation, and 100 pli floating roller peel. The cured adhesive is tough and resilient.

Key features

  • Filter-bonding formulation: Two-component polyurea elastomeric adhesive developed for filter assembly applications.
  • Controlled two-component processing: Uses a 100:60 resin-to-hardener ratio by weight or volume with a typical 15-minute pot life at 77°F (25°C).
  • Resilient cured performance: Typical cured properties include 475% elongation and 100 pli floating roller peel under the stated test conditions.

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
