Description

Lord 3135 A/B & 3135/7111 is an epoxy-based, roomtemperature-curing structural adhesive. Most metals, wood, glass, concrete and masonry, and various synthetic materials can be bonded with this adhesive. It provides high strength bonds, with a degree of flexibility in the bondline.

This polymer adhesive comprises two parts: the 3135 A Resin, and the curing agent, 3135 B (7111). These components should be thoroughly mixed in the recommended proportion just prior to use.

In general, this adhesive is characterized by

  • Long pot life
  • Low rate of shrinkage
  • Excellent resistance to mechanical impact, and shock
  • Good electrical resistance 
  • Excellent adhesion to a multitude of substrates 
  • Good machinability. 

Lord 3135 A/B & 3135/7111 is an excellent adhesive for bonding “skins” to plastic or metal honey-comb cores, polyurethane foams, and phenolic and epoxy laminates.

This curing agent, 3135 B (7111), has a very low level of toxicity. It is possible to reduce the viscosity of the curing agent by heating to 65°C. However, warming the material will shorten the pot life of the mixed compound. The curing reaction commences as soon as the parts are mixed together.
