Epoxy Systems and Versatic™ Monomers for Construction Adhesives

For adhesives serving the Construction and Infrastructure market, Hexion offers a wide range of epoxy systems that bond metal, concrete, plastics and glass. Our waterborne, solvent-free, high solids and solvent borne systems featuring EPIKOTE™ epoxy resins and EPIKURE™ curing agents combined with HELOXY™ modifiers help produce adhesives with:

• Good adhesion on various substrates
• Fast cure, even at low temperatures
• Solvent resistance
• Enhanced mechanical properties
• Good flexibility and impact resistance
• Low viscosity
• Electrical resistance
• Excellent water resistance
• High Tg
• Range of pot life
• Low yellowing

These adhesives are useful in a wide variety of applications, even where a high degree of thermal and chemical resistance and water impermeability are required in addition to good mechanical properties. Examples include:

• Bonding prefabricated concrete roadways
• Concrete pile splicing
• Bonding cable trays to concrete
• Traffic marking
• Tile adhesives
• Steel/concrete connections (metal fixtures to concrete structures such as rail-to-ground)

Emulsions containing VeoVa™ monomers exhibit enhanced alkali resistance and are useful for the formulation of adhesives for cementitious substrates. These emulsions may also be dried into redispersible powders for use as additives in various types of mortars.
