LRB
(Liquid Rubber Base)

PRODUCT INFORMATION DATA SHEET

Single Component Polyurethane Elastomeric Coating

PRODUCT DESCRIPTION:

LRB  is a single component, high solids, water inducted, low V.O.C. environmentally safe, liquid applied, hybrid polyurethane protective membrane.

LRB  is a low odor & solvent free  waterproofing membrane that can be used either indoors or outdoors.  LRB will bond permanently to properly prepare concrete, wood, aluminum, steel, and some plastics, as well as most all other standard building materials. 

LRB will not blister, crack, peel, or delaminate from exposure to extremes of ambient heat or cold as low as -45°F. It will withstand extreme Hydrostatic Pressure.

RECOMMENDED USES:

• Crack repair and filling
• Lifetime Roof Membrane

• Expansion joints
• Tank coating & Repair
• Floors
• Parking Decks
• Adhering Tile
• Waterproofing
• Protective Coating
• Secondary Containment
• Radon Mitigation
• Swimming Pools
• Boats and Marine Applications
• Sea Walls

PACKAGING:

• Quarts
• Gallons Pails
• 5 Gallon Pails
• 53 Gallon Drums
• 250 Gallon Totes

TECHNICAL DATA:

• 3200 psi tensile strength
• 600% elongation
• Volume solids-91%
• Will Cure At Any Thickness – In 1 Application
• Coverage varies upon thickness
• Non-flammable, non-combustible / solvent free
• Viscosity ± 600 cpois
• Package Life – 2 Years
• Temperature Range -60°to 250°F
• Cure Time (77°F @ 50% RH)
• Pot life 4-30 min.

*depending on activation*

• Cure Solid – 4 Hours
• Colder Temperatures will slow curing

THICKENING ADDITIVE:

T.A.V. (Thickening Activator) Is mixed with LRB to adjust its viscosity from a thin liquid to a caulk grade consistency or any consistency in between.  For patching joints, cracks, seams, holes, profiling, etc…

ADVANTAGES:

• Will cure at any thickness in 1 application
• Will force cure tack free 4 min. (in a form)
• Will cure overnight at 15°F
• Highly abrasive resistant
• Resistant to most oils, solvents, caustics & acids
• Can be brushed, rolled, squeegee, or sprayed
• High solids, high spread rate
• May be subjected to rain, snow, or extreme cold without affecting it’s curing
• LRB may be subjected to extreme cold during shipping, handling & storage without ill effects
• Bonds to itself, new-to-old, with proper surface preparation
• Completely Water-Proof not “Water Resistant”
• Not water based or water soluble
