Description
Key Bond™ is an organic polymer supplied as a one-component white liquid at a consistency slightly thicker than water. It is a
high solids (49%) acrylic emulsion designed to be used as an admixture to sand and cement mixes or straight as a "paint on" type concrete
bonding agent.
When used as an admixture, Key Bond™ will increase the adhesion, cohesion, and chemical bonds of cement mixes. It improves
water and weather resistance qualities, concrete curing, and reduces shrinkage cracking. It also aids in creating hard, durable, and chemical resistant
concrete surfaces.
Cement mixes prepared with the addition of Key Bond™are suitable for both exterior and interior applications and can be
installed in thicknesses ranging from a fine skim coat to whatever depth is necessary. Key Bond™ is also the product used as the latex resin
additive or activator in many of the spray deck products on the market today.
When used as a "paint on" bonding agent Key Bond™ will create better bonding between a compatible concrete
substrate and a suitable cementitious top layer.
Uses
The many performance feature of Key Bond™ provides a product of exceptional versatility. It improves the adhesion, flexural
and shear bond strength of cement mixes. May be used in areas subject to high humidity or immersion in water.
When used as an admixture in replacement of part of the mixing water, Key Bond™ reinforced cement and sand mixes are highly
hydrophobic, have greater adhesion, and are more resistant to attacks of acids, alkalis or chemicals.
Cement based mixes prepared with Key Bond™ as an admixture result in a hard, tough surface with improved scrub resistance and
water repellent qualities. Important application areas include patching and resurfacing, spray and fill coats, stucco, spraydeck cementitious coatings,
industrial concrete floors, and thin topping systems.
When used as a bonding agent adhesive, the Key Bond™ glue line becomes an integral part of the interface between the
cementicious material and the surface to be bonded. It creates a multiple bond (chemical and mechanical) between materials assuring top-level adhesive
performance.
