Features and
Benefits
Nonflammable - safer for
workers. Does not require
expensive explosion-proof equipment.
Will not deplete the ozone.
Environmentally and Chemically Resistant - resists sunlight, weathering, humidity, and salt spray. This adhesive is solvent resistant once it has cured. Painting and most cleaning processes do not affect bond strength.
Surface Preparation
Prior to mixing and applying this adhesive, the bond
surface
should be free of dirt, oil contamination and loose
particles. For most plastics, cleaning the surface with a
clean, dry cloth or a cloth dampened with isopropyl
alcohol will
suffice. Metal surfaces should be primed or
grit
blasted and solvent washed, followed by priming for
optimum bond performance.
Mixing
This adhesive is designed for use with Lord-PakTM
hand
held cartridges. The minimum recommended static mixer contains 24
elements. Open time is one to two minutes at 24°C (75°F).
