Description: Ready-to-use aluminium filled repair and patching compound. Single component dent and body filler.
Colour: Metal gray. Aluminium when buffed or sanded.
Adhesion: Excellent adhesion to clean, dry surfaces of metal (aluminium, steel, stainless, brass, bronze, cast iron, copper, lead...), wood, hard plastic, and glass. No heat needed; hardens upon exposure to air. Please note: Lab-metal will not bond two parts together; Lab-metal requires air in order to dry.
Hardness: 81 on Shore D scale
Coefficient of Linear Expansion: 27 x 10-6 mm/mm per °C
Strength: Tensile: 4.48 mPa
Compressive: 138 mPa
Water pressure: 344 kPa
Specific gravity: 1.95 at 24°C
Weight: One cubic inch: 1.9 gm/cc
Heat resistance: When dry and hard, withstands temperatures to 176ºC and is not affected by cold to -40ºC. Withstands higher temperatures (up to 218ºC) if heat exposure is less than 20 minutes. (For prolonged higher temperatures, Hi-Temp Lab-metal is available.)
Chemical Resistance: Not affected by mild acids, gasoline, petroleum, petroleum solvents, oil or L.P. gas. Alkalis will attack Lab-metal slowly, but only after extensive immersion.
Combustibility: Dry and hard material will not support combustion.
Conductivity: A non-conductor at normal voltage. Not considered an insulator. Accepts ground for powder coating.
Thermal Conductivity: Estimated 25-50 BTUs per sq. m, per hour, per ºC.
Mechanical Properties: Strong and durable. Can be milled, sawed, drilled, tapped, sanded, ground, filed. Does not shrink, chip, crack or peel, and is easily feather edged. Can be painted without lifting paint.
Drying time: Dependent upon thickness of application. Under normal conditions, a 1.5mm application hardens in 1-2 hours. A 3mm application hardens in 3-4 hours at ambient temperatures. Brush or spray applications (Lab-metal thinned with Lab-solvent) dry very quickly.
Shelf life: Two years in factory-sealed can. For extended storage, add Lab-solvent as instructed. Store in a cool place.
