The Science Behind GoNano
The Ultimate Roof Upgrade.
GoNano is the first and only company in North America to introduce a next-generation sealant that eliminates the need for traditional alternatives. Backed by decades of scientific research and rigorous peer review, our nanosilica technology offers unmatched durability and long-term cost savings—making it the smarter, stronger choice over conventional asphalt shingle solutions.
GoNano vs Traditional Sealants
Traditional Sealant
- Acts as an isolated, protective layer
- Typical repair on microscale, adds layer of oil
- Less durable, flexible and resilient to aging due to environmental conditions
GoNano Sealant
- Modifies the mechanical properties of asphalt
- Nanoscale (1000X smaller than a micro meter) forms precise shapes into asphalt pores
- Bonds to each asphalt shingle, and each shingle to the other
Protection with GoNano's Roof Sealer
Shingle Classes
Class 1
Least resistant, can withstand at most a 1.25-inch steel ball test.
Class 2
Can withstand at most a 1.5-inch steel ball test
Class 3
Can withstand at most a 1.75-inch steel ball test
Class 4
Highest resistance, can withstand up to a 2-inch steel ball test.
For GoNano to earn a Class 4 certification, a 50.88mm(2-in) diameter steel ball was dropped from 20 feet above a vulnerable section of a shingled roof. Following these tests, roofs treated with GoNano showed no signs of damage and/or cracking. One treatment from GoNano’s sealant transforms Class 1 shingles into Class 3, and two treatments into Class 4.
The Nano Application
The evolution of GoNano technology created a shift in how sealants are approached. A regular shingle is sealed with oil, filling up the space in between shingles. GoNano modifies the molecular structure of asphalt shingles permanently. After application, a reaction occurs within each shingle. This reaction fuses both organic and inorganic material, creating new chemical links, called S1 particles. These S1 particles link shingle granules together, working from the inside out, creating a unified barrier against environmental strains and saves you money by extending the lifespan of your roof.
The outcome is a strong, continuous layer that resists environmental strain.
Nanosilica is an inorganic nanomaterial closely related to silica, but distinguished by its exceptionally high silica content—up to 99% density. It must be synthetically produced using one of three methods
- The precipitation method, where silica reacts within a solvent and is purified and dispersed;
- The hydrothermal or solvothermal method, which involves precipitation under high-pressure and high-temperature conditions;
- Thermal reduction, where silica is exposed to extreme heat, ranging from 1700°C to 2300°C.
Once formed, nanosilica owes its enhanced performance to its pozzolanic reactivity—a chemical process that enables it to fill pores and improve material strength.
GoNano Advantages
Improved flexibility
Resilient to stretching, built to handle pressure, and engineered to avoid fractures.
Water Proof
Hydrophobic surface, deep moisture protection, and sealing power against water and ice.
Adaptive endurance
Survives the test of time through constant strain and climate related shifts.
Environmental Impacts
GoNano’s technology has been categorizedin accordance with the Occupational Safety and HealthAdministration standards (OHSA) as being:
- “Quickly biodegradable”
- “No bioaccumulation potential”
- “No harm to aquatic organisms”
In the coming years, the effects of climate change will mean an increase in severity of hail storms. Impact-resistant shingles will be a necessity for protection against increased frequency and strength of future storms.
GoNano is therefore safe for the environment and on human health.
