Lord 304
General-Purpose, High-Viscosity, Two-Part, Epoxy Adhesive
Description:
Lord® 304 adhesive is a general purpose, high viscosity,
two-part epoxy used for applications that
require gap filling or non-slumping
characteristics on a vertical surface. The cured adhesive offers
strong, durable, chemically and environmentally resistant bonds. Lord
304 adhesive has demonstrated excel-lent adhesion to prepared metals,
FRP, phenolic, wood, prepared rubber, and other materials.
Features and Benefits:
Contains No Solvent -
100% Solids,
nonflammable and virtually
odorless.
Excellent Stability - provides a two-year shelf life.
Proven Environmental Resistance - resists dilute acids, alkalis, solvents, greases, oils, moisture, sunlight, and weathering. Temperature resistant from -34°C to 121°C(-30° F to 250° F).
High Strength - provides
load-bearing properties equal to or greater than the products being bonded in many cases.
Variable Cure - cures completely at room temperature or much more quickly at elevated temperatures.
Excellent Engineering Properties - provides low shrinkage, good creep properties, and low water absorption.
Flexible Mix Ratio - accommodates a range of service temperatures and stress loads through modification of the resin-to-hardener mix ratio.
