Harmonization Code : 3919.10.80 | Other self-adhesive plastic rolls not exceeding 20 cm wide.

LORD 7100B

Main features

  • High-Strength Urethane Bonding
  • Primerless Bonding to Many Plastics
  • VOC-Free Weathering/Aging-Resistant Urethane

Product Description

LORD® 7100-A/B Urethane Adhesive is a two-part, high-strength urethane adhesive formulated for bonding cloth, paper, plastics, foams, rubber, painted metals and powder-coated metals. The system combines an isocyanate-based 7100-A resin with a polyol-based 7100-B curative and can be cured at room temperature or with elevated heat for faster processing. Once cured, it forms a glossy black bond with resistance to solvents, weathering and aging.

Key Features

  • Broad substrate capability for cloth, paper, plastics, foams, rubber, painted metals and powder-coated metals.
  • High-strength plastic bonding without crazing, attacking or reducing the strength of the plastic substrate.
  • Primer reduction on many plastics to help lower material and labor requirements.
  • Solvent-, weathering- and aging-resistant performance after cure, with no VOC content or ozone-depleting chemicals.

Applications / Suitable for

  • Plastic and foam assemblies
  • Rubber bonding
  • Cloth and paper laminations
  • Painted-metal and powder-coated-metal assemblies

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
A (Resin): 3000 -16,000 | B (Curative): 45,000 - 72,000 mPa.s
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.
A (Resin)/ B(Curative): >93 °C
