If your one-component coating system struggles with poor adhesion, slow cure, or yellowing under UV, you’re not alone.
Formulators, chemists, technical directors, and contractors alike face the same balancing act… simplifying application without sacrificing performance. Traditionally, that meant compromising on cure rate, chemical resistance, or substrate flexibility. But new modified hydrogel silane technology is rewriting the rules of what a single-component coating can do.
One of the most exciting developments in the protective and decorative coatings space is the advancement of single-component moisture-cure modified hydrogel silane technology. These systems are redefining what is possible in terms of versatility, ease of application, and film performance, and they are now accessible to formulators of all levels.
The Challenge with Traditional 1K Systems
One-component coatings have always promised convenience:
- No mixing
- No pot life
- Easy application in the field
But those benefits often come at a cost:
- Weak adhesion to glass, polycarbonate, or aged concrete
- Inconsistent UV resistance and yellowing
- Low chemical or water resistance
- Limited substrate range
The need for a 1K system that performs like a 2K has never been more urgent — especially in high-labor, VOC-restricted, or multi-surface environments.
What Are Modified Hydrogel Silanes?
Modified hydrogel silanes are reactive silane-based molecules engineered to cure upon exposure to atmospheric moisture. Once exposed to humidity, the silane groups crosslink and form a durable, highly resistant film.
But what makes modified hydrogel silanes different from traditional silane or urethane systems is their unique balance of elasticity, adhesion, and environmental durability. They combine the crosslinking power of silane chemistry with a more flexible, hydrogel-like backbone that improves compatibility and performance on both porous and non-porous substrates.
What sets them apart
Moisture-cure systems have several major advantages for formulators, contractors, and applicators alike:
- Single-component simplicity with no pot life restrictions
- Ambient cure without the need for added hardeners or heat
- Strong adhesion to a wide range of surfaces (even glass, concrete, and plastics)
- Excellent chemical and UV resistance
- Low VOC options when formulated with the right solvent package
- Excellent elasticity
These are true one-component systems that don’t act like watered-down versions of 2K urethanes… they compete head-on with them. This makes them ideal for coatings used in environments where application speed, substrate variability, and performance expectations are all high.
Introducing TERASIL®: Next-Generation Hydrogel Silane Technology
Advanced Performance. Simplified Application.
Pflaumer’s TERASIL® platform delivers advanced single-component, moisture-cure hydrogel silane technology that offers excellent adhesion, flexibility, environmental durability, and non-yellowing clarity on a wide range of substrates.
TERASIL® 1: A ready-to-use, moisture-cure hydrogel silane featuring a clear, non-yellowing finish available in satin or gloss. Designed for universal sealing and adhesion across a wide range of substrates.
TERASIL® 1NS: Formulated with higher solids, TERASIL® 1NS offers the same performance benefits as TERASIL® 1, but gives formulators the flexibility to select their preferred solvent or diluent for custom application needs.
Both products offer rapid cure, strong chemical resistance, and superior surface penetration. They can be used standalone or as part of multi-coat systems depending on your application requirements.
Real-World Applications
Pflaumer’s hydrogel silane technology is ideal for:
- Concrete sealers and grind-and-seal systems
- Wood finishes for furniture, cabinetry, or architectural surfaces
- Primers and topcoats for metal, steel, and composite substrates
- Clear or pigmented coatings for plastics, glass, and polycarbonate
- Flexible substrate applications (with appropriate testing)
- Sealers under polyaspartic, epoxy, urethane, and MMA topcoats
Compatible with common urethane-grade solvents:
- PCBTF
- t-Butyl Acetate
- PM Acetate
- TERAFLEX® DME-200
Formulators can create topcoats, primers, and specialty finishes without needing isocyanates or hardeners.
