Polyurea is more flexible than epoxy. What does this mean to you? Increased durability.
Polyurea's flexibility allows the coating to remain intact when concrete expands or contracts as a result of changes in temperature, while epoxy is very rigid and can crack.
Epoxy has an estimated 60 lb to 80 lb pull test whereas the Penntek poly system has a 650 lb pull test. This major difference is critical as it relates to durability under extreme conditions.
UV stability is 100% warranted by Penntek. It will not fade or yellow, like epoxy floor coatings will.
Epoxy product floors never stop curing over time, become more brittle and increase the potential of failure.
Polyurea seeks out any moisture within the concrete. As a result, it penetrates the concrete and mechanically locks in to produce a superior bond.
Polyurea coatings will not chip or peel under commercial applications and are resistant to salt, oil, gas, and many common chemicals used in working or home environments.
Epoxy floor products are typically applied with a "Thicker is better philosophy." A polyurea floor is applied and is stronger with a thin coat. Thicker is not better with polyurea. The actual thickness of our completed Evolution Chip system ranges from 22 to 26 mils.
The Penntek polyurea system has been designed by contractors to be unique in that it has a long pot life (working time) when being applied. This allows for less labor and faster installation. It employs a short cure life (time it takes to fully cure) so the surface can be used sooner (24 hours later) without concern for an uncured surface. This means in a commercial application you would not have to be without your facility for 2-3 days like you would with a full epoxy system.
The Polyaspartic topcoat made by Penntek is 100% antibacterial, antimicrobial and is warranted to not fade or discolor for the life of the product. It is also non-porous and nothing such as mold or mildew can grow on the surface. Commercial applications where health codes or cleanliness is essential, the Penntek product is optimal. These include, but are not limited to, restaurants, hospitals, laboratories, etc. The system meets USDA requirements.
Polyurea flooring systems have very low or no VOC's, meet the rigorous standards for California and are offered with "100% solids." Other less expensive epoxy products may be as little as 70% solids, meaning 30% of the product includes solvents or water that evaporates leaving less of the coating to protect the surface.
