Best Applications for Semi-Self-Leveling Sealants | Seal Bond® 190

In industrial environments, the right sealant can make or break a job. Whether you’re sealing equipment bases, trailer floors, or warehouse thresholds, a poor-performing sealant can lead to premature failure, water intrusion, and costly downtime.

For applications at or near floor level, semi-self-leveling sealants have become the go-to choice for professionals who need long-lasting, high-performance results. Their balance of flowability and control makes them ideal for creating uniform, durable seals that stand up to vibration, movement, and environmental stress.

What Is a Semi-Self-Leveling Sealant?

Unlike fully self-leveling sealants—which spread freely and are limited to flat, horizontal surfaces—a semi-self-leveling sealant offers controlled flow. 

• Semi-self-leveling sealants move just enough to fill joints and imperfections without running or dripping, even on slightly sloped or vertical surfaces.
• Once cured, semi-self-leveling sealants form an elastic, watertight bond that withstands expansion, contraction, and impact over time.

This balance makes it ideal for various industrial sealing tasks where precision and consistency matter. For professionals, that means faster application, fewer touch-ups, and a cleaner finish.

Top Industrial Applications Benefitting From Semi-Self-Leveling Sealants

1. General Sealing Applications

Semi-self-leveling sealants are ideal for horizontal and near floor joints where precision and protection are key. Common uses include:

• Sealing floor joints, thresholds, and equipment bases
• Preventing water intrusion, dust, and debris from entering sensitive areas
• Reducing contamination and corrosion in demanding industrial environments

Because these sealants maintain elasticity under temperature fluctuations, they help prevent cracking, adhesion loss, and premature seal failure—keeping operations running smoothly.

2. Overlap Seam Sealing

Consistency is everything when sealing overlapping metal seams, panels, or fabrication joints. Semi-self-leveling sealants deliver:

• A uniform, watertight barrier that resists cracking and shrinking
• Excellent adhesion under mechanical stress and vibration
• A clean, professional finish with minimal tooling or mess

Best for: Metal fabrication, panel assembly, HVAC housings, and industrial enclosures.

3. Transportation Sealant

In transportation and fleet applications, exposure to vibration, flexing, and extreme weather demands reliable flexibility and strength. Semi-self-leveling sealants are used for:

• Truck and trailer assembly
• Container and chassis sealing
• Fleet repair and maintenance

They bond securely to metals, composites, and coated surfaces, helping prevent leaks, corrosion, and premature wear. The result: fewer maintenance cycles and longer vehicle service life.

Performance advantage: These sealants are flexible enough to absorb movement, yet durable enough to withstand years of road vibration.

4. Commercial & Recreational Vehicle Repair

Speed and reliability matter when repairing RVs and trailers. Semi-self-leveling sealants make the job easier by offering:

• Smooth, uniform finishes with minimal tooling
• Weather- and UV-resistant performance for interior and exterior joints
• Strong adhesion to a variety of substrates used in RV manufacturing and repair

Typical applications:

• Floor and seam sealing
• Window, vent, and trim repairs
• Roof and body panel maintenance

Pro Tip: Every application is unique. Contact your Seal Bond Representative for help evaluating substrate compatibility, environmental factors, and automation setup recommendations.

Why Seal Bond® 190 Stands Out

When it comes to semi-self-leveling performance, Seal Bond® 190 is engineered to simplify application and improve long-term results. Built on advanced hybrid polymer technology, SB 190 delivers a combination of strength, flexibility, and environmental safety unmatched in its class:

• Engineered for efficiency: Easy to dispense, spread, and tool for faster production and cleaner results.
• Uniform finish: Semi-self-leveling formulation eliminates uneven seams and minimizes rework.
• Lasting durability: Reduces maintenance, labor costs, and downtime by maintaining integrity over time.
• Trusted reliability: Backed by Seal Bond’s commitment to responsive support, custom solutions, and decades of proven performance across industrial markets.

Key Features of SB 190:

• One-component, moisture-cure hybrid polymer technology — applies easily and cures quickly with ambient moisture.
• Unprimed adhesion to a wide range of substrates, including aluminum, steel, wood, PVC, fiberglass, coated
  metal, and more.
• Solvent- and isocyanate-free with ultra-low VOCs for safer application and compliance with strict environmental standards.
• Water-resistant and UV-stable, maintaining performance in both indoor and outdoor conditions.
• Permanent elastomeric bond that absorbs movement and vibration without cracking or shrinking.

SB 190 is available in black, gray, and white and can be supplied in cartridges or pouches for convenient use with manual or automated dispensing systems.
