Frequently Asked Questions
Q: What makes graphene-modified polyurethane different?
A: Graphene nanoplatelets create a physical barrier that dramatically reduces permeability while reinforcing the polymer matrix. The result is a coating with superior mechanical properties, chemical resistance, and longevity compared to conventional polyurethanes.
Q: Is ProFlex 9000G suitable for potable water contact?
A: A special NSF/ANSI 61 certified formulation is available for potable water applications. Specify ProFlex 9000G-PW when ordering.
Q: What is the expected service life?
A: 25+ years in properly specified and applied systems. Actual longevity depends on service conditions and film thickness.
Q: Can it be applied in cold weather?
A: Minimum application temperature is 40°F (4°C). For cold weather applications, consult technical support for special procedures.
Q: How does it compare to polyurea?
A: ProFlex 9000G offers similar rapid cure but with significantly better adhesion, chemical resistance, and ease of application. It requires less specialized equipment than pure polyurea systems.
Q: Is it UV stable for exposed applications?
A: The standard formulation is suitable for exposed applications with minimal color change. For long-term architectural exposure with critical color retention, consider ProFlex 9000G-UV (aliphatic version).
Q: How do I handle the two-component mixing?
A: Use the entire unit (4:1 ratio). Mix thoroughly with mechanical mixer. For large projects, plural-component spray equipment eliminates manual mixing.
Q: What reinforcement options are available?
A: ProFlex 9000G Reinforcement Fabric (polyester, 4 oz/yd²) for joints and cracks. ProFlex 9000G Heavy Fabric (10 oz/yd²) for full reinforcement in extreme service.
Q: Can I apply over existing coatings?
A: Only if the existing coating is sound, clean, and compatible. Always perform adhesion testing. For critical applications, complete removal is recommended.
