IC-985

Aliphatic Polyaspartic

IC-985 is a two-component, 100% solids, VOC-compliant, long working-time aliphatic polyaspartic coating designed for UV-stable floor topcoats. It provides outstanding appearance along with superior chemical, UV, and solvent resistance. The system offers excellent physical properties and complies with CFIA standards.

Surface Preparation
Old concrete must be mechanically prepared (shot blasting, grinding, or sand blasting). Remove all oils, sealers, curing agents, and contaminants. Do not apply on wet substrates. Check moisture, chloride, and pH levels before application.
New concrete must cure at least 30 days and meet minimum strength requirements. Mechanical preparation is required. Primer (SCI-100) is recommended to seal porous surfaces.
Mixing
Precondition materials to at least 15°C. Mix each component separately. Combine Part B into Part A (1:1 ratio) and mix for at least 3 minutes at low speed (300–450 RPM). Scrape sides and bottom to ensure uniform mix. Only mix quantities usable within pot life.
Application
Apply using a rubber squeegee or rake, followed by back-rolling to achieve a uniform coating. Avoid puddling.
Cleaning
Clean tools with appropriate solvent (Xylene). Once cured, material can only be removed mechanically.
Restrictions

Application temperature: 15°C–30°C (59°F–86°F)
Maximum relative humidity: 85%
Substrate moisture must be <4%
Do not apply on porous substrates prone to moisture transfer
Protect from moisture and condensation for 24 hours
