Three Bond 1375B - Anaerobe Klebedichtung - Hohe Festigkeit - 250 g Flasche

Three Bond 1375B Overview

The Three Bond 1375B is an anaerobic adhesive based on methacrylate, serving as a single-component sealant for high-strength fits. The green sealant provides reliable closure in pressure loops and vibration-resistant applications.

Thanks to its solvent-free formulation and its high strength, it replaces press-fit seals in many applications. The listed values for shear and peel strength demonstrate its reliability even under dynamic loading.

Suitable for high-strength fits

Advantages in industrial seals

The seal usually does not cure by contact with metal surfaces in the presence of air; instead curing occurs in the absence of air on the contact surface, thereby achieving up to 30–35 MPa shear strength. The 0.01 mm gap tolerance enables precise seating seals even on tightly toleranced surfaces.

Technical data of Three Bond 1375B

• Main component: Methacrylate

Structure and material choice

The adhesive is single-component and solvent-free. The base substance is a methacrylate that forms a robust bond in green sealing compound for fits.

Processing & Practice

• Surfaces thoroughly clean and degrease.
• Apply the seal evenly.
• Join components and fix until adhesion begins.
• After about 2 h, functional strength is reached; if necessary, observe additional curing.

Core advantages in practice

With high shear and peel strength, the 1375B provides a reliable alternative to press fits, especially in dynamically loaded applications. The solvent-free formulation facilitates handling, reduces health and environmental burdens, and supports easy processing.
