The Science of Asphalt Sealcoating: What’s in the Sealer & Why It Matters
Asphalt sealcoating is an engineered mix of binders, emulsifiers, aggregates, polymers, and targeted additives. Binders form a protective film; emulsifiers keep it sprayable. Aggregates add skid resistance and wear. Polymers boost toughness and flexibility, while additives fight UV, oxidation, and oil. Coal tar offers fuel resistance but higher PAHs; asphalt emulsion trades fuel resistance for […]
