DESCRIPTION
EF-301 is a low-sheen, slip-resistant urethane topcoat that stands up to chemicals and traffic.
Evershield-301 (EF-301) is a 3-component, high-solids, aliphatic moisture-cure polyurethane coating designed as a UV-stable, chemical-resistant topcoat. Instead of a mirror gloss, it cures to a refined satin finish that hides scuffs and foot-traffic marks, and because it is aliphatic, it will not yellow under sunlight. It is the finishing layer that protects and beautifies a cured epoxy or urethane floor.
EF-301 is built to take abuse. It posts best-in-line abrasion resistance at just 0.02 g of Taber loss, plus excellent chemical resistance to guard the system beneath. Formulated with aluminum oxide, it delivers roughly 0.80 DCOF wet traction for genuine slip resistance underfoot, which suits ramps, entries, kitchens, and wet-prone areas.
It is also one of the cleanest coatings you can specify, at under 10 g/L VOC, LEED v4 low-emitting, and it meets CFIA and USDA requirements for indirect food contact. A 1-gallon kit covers about 500 sq ft at 3.2 mils, going down thin and even. EF-301 is a 3-part system (4 parts hardener A : 1 part resin B by volume, plus the part C powder). Roll it with a urethane-grade roller in V-shaped cross passes, then re-roll in straight passes to avoid marks. It is a finish coat for use over a cured epoxy or urethane base, not bare concrete.
Key Features & Benefits
- UV-Stable Satin Finish: Aliphatic polyurethane gives a refined, low-sheen satin look that will not yellow, ideal where high gloss shows every scuff.
- Slip-Resistant: Formulated with aluminum oxide for ~0.80 DCOF wet traction and added safety underfoot.
- Best-in-Line Abrasion & Chemical Resistance: Just 0.02 g Taber abrasion loss with excellent chemical resistance to protect the floor below.
- Ultra-Low VOC (<10 g/L): One of the lowest-VOC topcoats available; LEED v4 low-emitting; meets CFIA and USDA requirements for indirect food contact.
- High Coverage: A 1-gallon kit covers ~500 sq ft at 3.2 mils DFT.
- Goes Over Epoxy or Urethane: Apply as the finishing coat over a cured epoxy or urethane base.
- 3-Component Moisture-Cure: Chemistry tuned for a hard, durable, weather-resistant film.
