LOTECH 7655-1 Structural Adhesive is a low-viscosity two-component adhesive designed for precision bonding, small-component potting, riveting and lamination applications. After the two components are mixed, the material cures at room temperature to form a red adhesive layer with low shrinkage, excellent impact resistance and good dimensional stability.

Product Overview

LOTECH 7655-1 is designed for applications that require a combination of structural strength, mechanical performance, electrical insulation and controlled appearance.

The adhesive has a relatively low-viscosity uncured consistency, helping it flow into narrow bonding areas and around small components.

After mixing the two components, the material cures at room temperature and develops a red cured bond line.

One of the important characteristics of LOTECH 7655-1 Structural Adhesive is its low curing shrinkage. Reduced shrinkage can help minimize stress on precision parts and bonded assemblies during the curing process.

The cured adhesive also provides excellent resistance to impact and maintains good dimensional stability over a relatively wide temperature range.

Key Features and Advantages

Low Shrinkage

LOTECH 7655-1 is designed to produce a low-shrinkage cured adhesive layer.

This characteristic is especially useful in precision assemblies where excessive curing shrinkage could introduce stress, alignment changes or dimensional movement.

Excellent Impact Resistance

The cured red adhesive provides strong resistance to impact and mechanical shock.

This makes the material useful for components exposed to vibration, handling loads or intermittent mechanical stress.

Low-Viscosity Application

The relatively low viscosity allows the adhesive to wet bonding surfaces and flow into small gaps.

This characteristic can be useful for precision components, optical assemblies and small potting applications.

Room-Temperature Cure

LOTECH 7655-1 Structural Adhesive cures after the two components are combined and does not require a high-temperature oven as part of the basic curing process.

Actual cure time and final cure conditions should follow the latest product TDS.

Chemical and Solvent Resistance

After full curing, the adhesive provides resistance to many commonly encountered chemicals and solvents.

This helps improve durability in industrial environments where the bonded assembly may be exposed to cleaning agents or chemical contact.

Dimensional Stability

The cured adhesive maintains good dimensional stability across a comparatively wide temperature range.

This characteristic is valuable for precision mechanical, optical and electronic assemblies.

Electrical Insulation

LOTECH 7655-1 can be used in applications that require electrical insulating performance in addition to structural and mechanical bonding.

Applications of LOTECH 7655-1 Structural Adhesive

Fiber Optic Bonding

LOTECH 7655-1 is suitable for selected optical-fiber bonding applications where low shrinkage and dimensional stability are important.

Glass Bonding

The adhesive can bond glass and is useful for selected optical, instrument and precision assembly applications.

Ceramic Bonding

LOTECH 7655-1 Structural Adhesive can be used for bonding ceramic components requiring a strong and impact-resistant adhesive layer.

Metal Bonding

The material is suitable for many metal bonding applications in industrial, electrical and mechanical assemblies.

Rigid Plastic Bonding

Many rigid plastics can be bonded with 7655-1. Compatibility testing should be carried out on the actual production substrate before mass use.

Small Component Potting

The low-viscosity system can be used for small-scale encapsulation and potting where controlled flow and low shrinkage are required.

Riveting and Reinforcement

LOTECH 7655-1 can also be used to reinforce riveted assemblies and improve load distribution around mechanically joined components.

Lamination

The adhesive is suitable for selected lamination applications involving compatible rigid materials.

Suitable Materials

Typical compatible materials include:

Glass
Fiber Optics
Ceramic
Metal
Selected Rigid Plastics
Precision Mechanical Components
Electrical Components
Optical Components

Actual compatibility should always be verified with the final production materials.
