Acrylic Membrane Curing Compound
CAS Number: 9003-01-4
Acrylic-based membrane curing compound is applied to freshly placed concrete surfaces to form a continuous, water-impermeable film that retains moisture for adequate hydration. It provides a reliable, cost-effective alternative to wet curing methods such as burlap or ponding, especially for large horizontal surfaces like slabs, pavements, and bridge decks. Available in clear and white-pigmented formulas; white-pigmented types also reduce surface temperature in hot weather.
Technical Specifications
| pH | 7.5-9.5 |
| appearance | Clear or white liquid |
| solid content (%) | 25±3 |
| coverage rate (m²/L) | 4–6 |
| water retention efficiency (%) | ≥90 |
Applications
- Concrete floor slabs and pavements immediately after finishing
- Bridge decks and horizontal infrastructure surfaces
- Precast concrete elements after demolding
- Shotcrete surfaces in tunnels and slopes
- Hot-weather concreting where evaporation control is critical
Key Features
- Forms a continuous moisture-retaining film in a single spray application
- White-pigmented type reduces solar heat absorption in hot weather
- Compliant with ASTM C309 Type 1 and Type 2 curing compound standards
- Easy spray application with standard garden or airless sprayers
