IC-859

Solventborne Aliphatic Polyaspartic Coating

IC-859 is a two-component solventborne aliphatic polyaspartic topcoat system designed to maintain the integrity of coating surfaces while providing excellent appearance. It offers superior mechanical properties along with UV stability, chemical resistance, and solvent resistance. This system complies with CFIA standards.

Advantages

Superior mechanical resistance
Good chemical and physical resistance
Easy-to-clean, bacteria- and moisture-resistant surface

Primary Applications

Industrial flooring
Bridges
Maintenance facilities
Aircraft hangar flooring
Car washes
Areas requiring a durable topcoat

Surface Preparation
Surface must first be coated and sealed with SCI-100 or SCI-300-8084 prior to applying SCI-300-8050.
Mixing

Step	Instruction
1	Pour all of Part B into Part A
2	Mix 2–3 minutes at 300–450 RPM
3	Gradually add Part C (aluminum oxide)
4	Mix until aggregate is evenly dispersed

Important:
Scrape container sides and bottom at least once during mixing. Ensure all Part B is fully added to avoid incomplete curing.
Application
Apply using a dip-and-roll method with roller and pan:

18" roller
10 mm lint-free nap
Load roller from pan
Redistribute aggregate before application
Apply at 4–6 mils
Maintain wet edge
Avoid overworking material

Cleaning
Clean tools with Xylene. Once cured, material must be removed mechanically.
Restrictions

Substrate moisture ≤4%
Substrate must be ≥3°C above dew point
Avoid condensation
Do not add solvent or water
Apply in ventilated area
Protect from moisture during first 24 hours

Health & Safety
Use PPE (gloves, goggles, respirator). Avoid skin/eye contact and vapor inhalation. Work in a well-ventilated area. Refer to SDS.
