HUMISEAL 2A13

Main features

  • 1:1 Part A-to-Part B Mixing
  • 60-Minute Pot Life
  • Thermal Shock and Vibration Protection

Product Description

HumiSeal 2A13 is a two-component, low-stress polyurethane encapsulant for electronic sealing and encapsulation. It mixes at 1:1 and cures to a clear, elastic material used for electronic packages exposed to repeated thermal shock and high vibration. Typical component viscosities are 2,700 cP for Part A and 7,500 cP for Part B. Typical processing times are a 60-minute pot life, 120-minute handling time, and full cure after 24 hours at room temperature or one hour at 65 deg C. Substrates include metals, glass, ceramics, and plastics.

Key features

  • 1:1 Part A-to-Part B Mixing: Typical component viscosities are 2,700 cP for Part A and 7,500 cP for Part B.
  • 60-Minute Pot Life: Typical handling time is 120 minutes under the stated conditions.
  • Thermal Shock and Vibration Protection: The cured encapsulant is used for electronics exposed to repeated thermal shock and high vibration.

Applications

Electronic sealing and encapsulation on metals, glass, ceramics, and plastics.

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.
