Description

Product Overview

F-61 combines a proprietary blend of polyol with Iso to create an intermediate speed, clear polyaspartic. F-61 is an 83% solids, low viscosity polyaspartic that provides easy application with a moderately fast dry time. It will not yellow or chalk over time and provides a great, high gloss finish with as little as 6 mils WFT.

Uses – F-61 is primarily used as a clear topcoat due to its unsurpassed UV and abrasion resistance. It can be applied to floors and walls and adheres well to many substrates including concrete, gypsum, cement board, metals and fiberglass.

Preparation

The coating installer should fully read and understand ICRI310.2R-2013 and OSHA 29 CFR 1926.1153 before starting preparatory work. The aim, of preparing a substrate for coating applications, is to roughen the surface, remove weak layers, contaminants, dirt, debris and present a solid, clean, dry substrate for the primer.

Benefits of Polymer Nation F‑61 Polyaspartic

F‑61 is a high‑performance, clear polyaspartic topcoat known for its durability, ease of application, and excellent gloss finish.

Key Performance Benefits

• High Gloss Finish: Achieves a 90+ gloss at 60° angle with as little as 6 mils wet film thickness (WFT).
• UV & Abrasion Resistance: Unsurpassed resistance to ultraviolet degradation and abrasion, making it ideal for long‑term protection.
• No Yellowing or Chalking: Maintains clarity and color integrity over time.
• Low Viscosity: Easy to apply with standard tools, even on complex surfaces.
• 83% Solids Content: Reduces VOC emissions and improves coverage efficiency.
• Versatile Substrate Adhesion: Bonds well to concrete, gypsum, cement board, metals, and fiberglass.
• Fast to Moderate Dry Time: Dry to touch in 4–5 hours; through dry in 10–14 hours; full cure in 7 days.
• High Hardness: Pendulum hardness reaches 50 at 7 days, with 18 at 24 hours.

Application Advantages

• Clear Topcoat Use: Primarily used as a clear protective topcoat over primers or other coatings.
• Flexible Thickness: Apply 5–15 mils on floors and 5–6 mils on walls.
• Ideal Temperature Range: Best applied between 70–90°F for optimal working and cure times.
• Low Odor: Especially in the LV variant, making it suitable for indoor or sensitive environments.

Practical Benefits for Installers

• Longer Working Time (LV variant): 20–25 minutes working time vs. 15–20 minutes for standard F‑61, allowing more flexibility on complex jobs.
• Easy Mixing: 1:1 liquid ratio by volume; mixing the entire kit avoids off‑ratio issues.
• Recoat Friendly: Can be recoated within 24 hours if needed.
• Clean Tooling: Tools can be cleaned with solvents like xylene or acetone.
