Product Description

3M Neoprene High Performance Contact Adhesive 1357L is a low-viscosity, one-part solvent-based neoprene contact adhesive for large-area and composite lamination. The gray/green liquid contains 17 to 19 wt% solids and has typical viscosity of 35 to 65 cP at 27 deg C, supporting spray, brush, or roller application. Applied to both prepared surfaces, it dries in about 10 minutes and provides an approximately 30-minute bonding range at 21 deg C and 35% RH. Uniform pressure develops immediate handling strength for machining or trimming after assembly. The adhesive bonds rubber, cloth, metal, wood, foamed glass, paper honeycomb, and decorative plastic laminates in supported industrial laminating and panel-construction work.

Key features

  • Low-viscosity application: Typical 35 to 65 cP viscosity at 27 deg C supports spray, brush, and roller coating.
  • Controlled bonding window: The adhesive dries in about 10 minutes and provides an approximately 30-minute bonding range at 21 deg C and 35% RH.
  • Immediate handling strength: Uniform assembly pressure supports machining or trimming directly after the bond is formed.

Applications

Applications include large-panel and composite lamination and bonding rubber, cloth, metal, wood, foamed glass, paper honeycomb, and decorative plastic laminates.

Thermal Properties
Flash Point
The flashpoint of a solvent is the lowest possible temperature at which it can vaporize to form an ignitable vapor. Flashpoint is often confused with “autoignition temperature”, which is the temperature at which a solvent ignites without an ignition source.

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
