DESCRIPTION
EF-290 is the high-build polyaspartic: the toughest, thickest clear finish in the Everflow line, laid down in fewer coats.
Polyflow-290 (EF-290) is a solvent-based, two-component, VOC-compliant, aliphatic polyaspartic polyurea coating developed as a UV-stable topcoat for jobs with limited downtime. It carries the highest solids content in the Everflow polyaspartic line at 90%, so it is engineered for a high-build clear coat over solid-color coatings and vinyl flake broadcast (chip) systems, laying down a thicker, more protective film in fewer passes.
As a true aliphatic polyaspartic, EF-290 will not yellow or chalk and keeps a brilliant, glass-clear high-gloss finish indoors and out. It delivers superior abrasion, chemical, and UV resistance, with just 0.03 g of Taber abrasion loss to protect the color and flake beneath from the heaviest traffic. And it cures fast: recoat in 2-4 hours, return foot traffic in 3-6, and vehicle traffic the next day.
EF-290 is flexible and durable. It stretches 40% at break to resist cracking, pulls 5,150 psi tensile, and offers ~0.75 DCOF wet traction. At under 50 g/L VOC it is LEED v4 low-emitting and meets CFIA and USDA requirements for indirect food contact. It is a finish coat, so apply it over a prepared base system, not bare concrete. It comes crystal clear (tinting available, though pigmenting can reduce chemical resistance). With a quick 15-20 minute working window, mix only what you can spread in time.
Key Features & Benefits
- Highest-Solids, High-Build: 90% solids lays down a thicker, more protective clear film in fewer coats than standard polyaspartics.
- UV-Stable Clear Finish: Aliphatic polyaspartic chemistry resists yellowing and chalking for a crystal-clear, high-gloss finish indoors and out.
- Maximum Abrasion & Chemical Resistance: Just 0.03 g Taber abrasion loss shields the color and flake beneath from the heaviest traffic.
- Fast Return to Service: Recoat in 2-4 hours and walk on it in 3-6, so you can reopen the space the same day.
- Built for Flake & Color Systems: The premium high-build clear topcoat over vinyl flake (chip) floors and solid-color coatings.
- Flexible & Tough: 40% elongation at break resists cracking; 5,150 psi tensile; ~0.75 DCOF wet traction.
- Low-VOC & Food-Plant Rated: <50 g/L VOC; meets CFIA and USDA requirements for indirect food contact; LEED v4 low-emitting.
