• Low Viscosity and Easy Application
• UV-Resistant and Non-Yellowing
• Compatible with Urethane-Grade Solvents

Performance You Can Count On

Cure Speed

• Tack-free in under 2.5 hours
• Through-dry in under 12 hours (at 50% RH, 23°C)
• Recoat window typically under 3 hours

Film Properties

• Achieves a high gloss finish
• Can be applied at 3 mils wet / 1 mil dry
• Excellent chemical and moisture resistance

Application Versatility

• Compatible with PCBTF, t-Butyl Acetate, PM Acetate, and TERAFLEX^® DME-200
• Can be applied via pump sprayer or ¼-inch nap roller
• Suitable for indoor and outdoor use across metal, wood, concrete, plastics, glass, polycarbonate, and polyester gel coats

Ideal for a Wide Range of Applications

TERASIL^® is engineered for demanding use cases, including:

• 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

Introducing TERASIL® 1 and TERASIL® 1NS

Pflaumer’s initial launch includes two high-performance variants:

TERASIL^® 1: A ready-to-use, moisture-cure hydrogel silane featuring a clear, non-yellowing high gloss finish. 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.
