Neoflex PU 25LM | Polyurethane Sealant

One-Component Polyurethane Sealant

NEOFLEX PU 25 LM polyurethane sealant is a one-component polyurethane sealant that cures when exposed to atmospheric humidity. It forms a highly flexible, durable, and weather-resistant joint with excellent adhesion to a wide range of substrates. Ideally suited for dynamic joints, it ensures long-lasting performance in both indoor & outdoor applications. It complies with ISO 11600 F 25 LM,
ASTM C920, ASTM C719 (Type S, Grade NS, Class 25, Use NT, M, A, O), and BS 6920.

Key Benefits:

  • Permanent elasticity with ±25% movement capability.
  • Non-sag & thixotropic properties for vertical & overhead applications.
  • No shrinkage after curing.
  • Can be painted with compatible elastomeric paints.
  • High mechanical performance with excellent adhesion.
  • Good resistance to weathering, aging, and chemicals.
  • Suitable for potable water applications under special conditions.

Neoflex PU 25 LM polyurethane sealant is suitable for a wide range of sealing and bonding applications, including:

  • Expansion joints between various construction materials.
