Introduction

The process of bonding glass to metal is prevalent in various industries, from electronics to automotive manufacturing. Ensuring a durable bond between these two dissimilar materials is crucial for the integrity and longevity of the final product. This article examines the materials, types of adhesives, the bonding process, and solutions offered by Dely Company.

Materials Consideration

Glass and metal have different thermal expansion coefficients and surface properties. Glass, typically an amorphous solid, does not expand as much as metals under heat. Metal surfaces may require additional treatment to improve adhesion.

Types of Adhesives

1. Epoxy Adhesives

Epoxy adhesives are known for their strong bonding and resistance to environmental factors. They can withstand temperatures ranging from -30°C to 150°C.

2. Silicone Adhesives

Silicone adhesives offer excellent flexibility and can accommodate the thermal expansion differences. They are suitable for temperatures up to 200°C.

3. Polyurethane Adhesives

Polyurethane adhesives provide a good balance of elasticity and strength, optimal for applications requiring impact resistance.

Process of Bonding Glass to Metal

The bonding process involves surface preparation, adhesive application, and curing. Proper cleaning and, in some cases, priming the surfaces are essential for optimal results. The curing time and temperature will depend on the adhesive type used.

Dely Company Solutions

Dely Company has developed specialized adhesives specifically for glass-to-metal bonding. Their product range includes:

• DelyGlasBond-100: An epoxy-based adhesive with a shear strength of 25 MPa.
• DelySil-200: A silicone-based solution for applications requiring flexibility, tested to withstand 10,000 thermal cycles from -40°C to 180°C.

Numerical Analysis of Adhesives

Performance metrics for adhesives include shear strength, tensile strength, and thermal resistance. DelyGlasBond-100 typically shows a tensile strength of 30 MPa, while DelySil-200 maintains structural integrity across temperature variations of -40°C to 180°C.

Applications and Limitations

Bonding glass to metal is widely used in automotive windshields, electronic displays, and architectural features. Limitations include potential stress concentration at the bond line and the need for precise application conditions.
