Aliphatic Urethane 510-CA™
Built for long-term durability and performance, Aliphatic Urethane 510-CA is a technologically advanced, high-solids, single-component, moisture-cure aliphatic polyurethane coating. Once cured, it forms a seamless, flexible, and waterproof membrane that resists lateral movement, shear stress, and normal expansion and contraction. Its low moisture vapor permeability helps increase resistance to moisture penetration, while the moisture-cure formulation allows for extended application windows during installation.

- Surface Preparation
Pressure wash the roof (2,500–3,500 psi) to remove dirt, debris, grease, mildew, and loose material. Ensure the surface is completely dry for proper adhesion.
Inspect and repair damaged areas. A primer may be required based on substrate age and condition.
- Mixing/Thinning
Mix thoroughly with a drill mixer for ~3 minutes for uniform consistency. If needed, thin up to 10% (1:10 ratio). Consult Technical Services for specific guidance.
- Application Methods
Apply using an airless hydraulic sprayer or a medium nap roller.
- Coverage Rates
Dries to the touch in 2–4 hours under normal conditions. Apply additional coats within 24–48 hours. Full cure occurs in 7–10 days, depending on temperature and humidity.
- Limitations/Precautions
Do not apply if surface temperature is below 40°F, as it may hinder curing. In cold weather, store indoors until use.
High humidity speeds curing; low humidity slows it. Avoid application if rain is imminent to prevent adhesion issues.
- Storage/Handling
Store in a cool, dry place, away from sunlight and heat. Keep containers sealed to prevent moisture exposure and premature curing.
While freezing rarely causes damage, extreme temperature fluctuations can affect consistency. Store in controlled conditions to prevent freezing.
- Cleanup/Disposal
Clean tools and equipment immediately after use with an appropriate solvent. Dried material may require mechanical removal.
Do not dispose of liquid material in drains or waterways. Follow local, state, and federal regulations for proper disposal of unused product and empty containers.
