Heng's 95502C NuFlex 311 Self-Leveling RV Silicone Sealant

Heng's NuFlex 311 RV Self-Leveling Silicone Sealant is a professional-grade, flowable sealant designed specifically for RV roof and exterior applications. This one-part, neutral-cure elastomeric silicone formula cures to form a durable, flexible, low-modulus seal that withstands the constant movement and temperature extremes RVs experience.

Key Features:

• Self-leveling formula flows smoothly into cracks and seams without tooling or spreading required
• Neutral-cure silicone won't corrode metal surfaces or damage sensitive substrates
• Low modulus design maintains flexibility through extreme temperature fluctuations
• Excellent adhesion to common RV materials including aluminum, fiberglass, vinyl, and EPDM rubber
• UV resistant formula prevents cracking and degradation from sun exposure
• Reduced labor costs due to no-tooling application method

Ideal for sealing roof vents, skylights, air conditioner bases, and other horizontal RV surfaces where a smooth, self-leveling finish is required. The elastomeric properties ensure the seal remains intact even as materials expand and contract with temperature changes.
