DESCRIPTION
The same UV-stable, crystal-clear polyaspartic finish — in a 3-gallon kit that covers more floor with a thin-to-medium build.
Polyflow-280 (EF-280) is a solvent-based, two-component, VOC-compliant, aliphatic polyaspartic polyurea coating developed as a UV-stable topcoat for jobs where installation downtime is limited. It's designed for a thin-to-medium build clear coat over solid-color coatings and vinyl flake broadcast (chip) systems, sealing in the finish and protecting everything underneath — and its larger 3-gallon kit covers up to 600 sq ft.
As a true aliphatic polyaspartic, EF-280 won't yellow or chalk, holding a brilliant, glass-clear high-gloss finish indoors and out. It provides superior abrasion, chemical, and UV resistance — just 0.03 g of Taber abrasion loss to protect the color and flake beneath from heavy foot and cart traffic. It cures fast, too: recoat in 2–4 hours, return foot traffic in 4–8, and vehicle traffic the next day.
Flexible and tough, EF-280 stretches 40% at break to resist cracking, pulls 5,150 psi tensile, and gives ~0.75 DCOF wet traction. At under 50 g/L VOC it's LEED v4 low-emitting and CFIA/USDA recognized for food-plant use. It's a finish coat — apply over a prepared base system, not bare concrete — and it comes crystal clear (tinting available, though pigmenting can reduce chemical resistance). Because the cure is quick, mix only what you can spread in 20–25 minutes.
Key Features & Benefits
- UV-Stable Clear Finish: Aliphatic polyaspartic chemistry resists yellowing and chalking for a crystal-clear, high-gloss finish that lasts indoors and out.
- High Coverage, 3-Gallon Kit: Covers up to 600 sq ft over an existing coating or 400 sq ft over vinyl flake — more floor per kit.
- Thin-to-Medium Build: Lays down a richer film than a thin-build topcoat for extra protection and depth.
- Fast Return to Service: Recoat in 2–4 hours and walk on it in 4–8 — reopen the space the same day.
- Superior Abrasion & Chemical Resistance: Just 0.03 g Taber abrasion loss shields the color and flake beneath.
- Flexible & Tough: 40% elongation at break resists cracking; 5,150 psi tensile; ~0.75 DCOF wet traction.
- Low-VOC & Compliant: <50 g/L VOC; CFIA/USDA recognized; LEED v4 low-emitting.
