LOCTITE 4013

Main features

  • Medium-Viscosity Cyanoacrylate Adhesive
  • ISO 10993 Biocompatibility
  • Disposable Medical-Device Assembly

Product Description

LOCTITE® 4013™ is a one-part, medium-viscosity ethyl cyanoacrylate adhesive formulated for rapid bonding of plastics and metals. Designed specifically for the assembly of disposable medical devices, the adhesive cures quickly at room temperature through exposure to ambient humidity and provides fast fixture times on a wide variety of substrates. LOCTITE 4013 has been evaluated using Henkel test protocols based on ISO 10993 biocompatibility standards, making it suitable for medical device manufacturing applications where dependable performance and rapid production throughput are required. The transparent adhesive delivers strong bonds, excellent handling characteristics and reliable mechanical performance after cure.

Key Features & Benefits

  • One-component cyanoacrylate adhesive requiring no mixing.
  • Fast room-temperature curing through ambient humidity.
  • Designed for plastics and metal bonding applications.
  • Medium viscosity supports controlled dispensing and gap filling.
  • Suitable for disposable medical device assembly.
  • Evaluated using ISO 10993 biocompatibility test protocols.
  • Excellent fixture speed and handling strength development.

Recommended Applications

  • Disposable medical device assembly.
  • Plastic-to-plastic bonding.
  • Plastic-to-metal 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.

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
400 - 800 mPa.s
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.
