LAS-320 is a specialized asphalt sealcoat developed with technology used for military runway construction. It offers a high-performance alternative to traditional sealcoats for long-lasting protection to asphalt surfaces. Unlike other sealcoat products, LAS-320 is a polymeric emulsion that penetrates and integrates into the asphalt surface to provide superior protection against environmental damage. It makes a molecular bond that penetrates and seals cracks making the surface impervious to water, fuels, oils, chemicals, Ultra Violet damage, and also helps prevent freeze-thaw issues.

Asphalt pavements do not last forever because these external factors destroy the oils that bind it all together. Heat & Sunlight accelerates the deterioration process; salt and other chemicals will also act as a catalyst. When oxygen and water contact this binder, a chemical change takes place. At first, this process is necessary for the pavement to become hard and firm. After time if this process is not stopped, complete deterioration will take place making the asphalt brittle and eventually reduce the pavement to a layer of loose stone.

Sealing your asphalt with LAS-320 is a great way to protect it from the elements that over time destroys it. Your asphalt is an asset that’s worth protecting and a little investment into sealing it can extend the life for many years, improve the curb appeal, and increase the value of your property. Using LAS-320 will help prevent water intrusion which leads to base failure, cracking, and potholes. As the climate changes, LAS-320 expands and contracts with changing temperatures unlike conventional sealcoating products, LAS-320 will not crack or fade, just one application can remain effective for ten years or more.

The easiest way to apply LAS-320 is by simply pouring it directly on the surface and spreading it with a broom. LAS-320 can also sprayed with an airless paint sprayer or with conventional asphalt spraying equipment. Typical application rates average 100 square feet per gallon depending on the surface texture, porosity, application method, and other factors.

Some benefits of LAS-320 include:

• No odor and No tracking
• Environmentally safe – No PAH
• Repels most liquids and chemicals
• Low VOC with only 94 Grams per Liter
• Dries quickly- usually less about 15 minutes
• Non-toxic – Non-hazardous – Non-flammable

LAS-320 VS Coal Tar Asphalt Sealers

Coal tar sealant is a thick, black goop applied to driveways, asphalt parking lots, playgrounds, and other asphalt surfaces. This type of sealcoat has high levels of toxic chemicals that can cause cancer and environmental harm. Coal Tar sealers contain toxic compounds known as polycyclic aromatic hydrocarbons, or PAHs, which can seep into the environment. As a result, several cities have banned the sale and use of these types of products and some localities are suing coal tar sealant manufacturers to get them to pay for the costly environmental cleanups.

The toxic dust from coal tar-based sealcoat doesn’t stay put. It seeps into water, evaporates into air and gets tracked into people’s homes.
