Description
Lord® 7412 is a 100% solids, single-component,
moisture-cure
adhesive, used for various thermoplastic
substrates and fabrics.
Features and Benefits
Non-flammable -
contains no solvents and does not require explosion proof equipment.
Single Pack - requires no mixing and produces less waste.
Moisture Cure - requires no heat or ovens for curing.
Environmental and Chemical Resistance - resists sunlight, weathering, humidity and salt spray. Once cured, it is solvent resistant. Painting and most cleaning processes do not effect bond strength.
Surface Preparation
Remove contamination from surfaces to be bonded.
Use
solvent wiping, scuffing or sanding for optimum
adhesion.
Mixing
Lord 7412 adhesive does not require mixing.
Application
Lord 7412 adhesive at 100% solids or diluted with
solvent to
60% TSC is an excellent adhesive for bonding
polyester reinforcement to an extruded Hytrel®
core. At
100% solids, Lord 7412 adhesive offers excellent adhesion between Hytrel
or TPU (thermoplastic
urethane) and
polyester or Kevlar®
reinforcement. For
adhesion between polyester or Kevlar and a nylon 11
core, a solution of Lord 7412 adhesive works best
