SOME CONSIDERATIONS REGARDING TRENDS IN AUTOMOTIVE ADHESIVE BONDING

For the future the evolution of adhesive bonding as a joining technique in automobile production points in two directions. On the one hand, well-known applications have to be optimized and improved to make them cost-effective but nevertheless reliable and trustful processes enjoying increasing acceptance for adhesive bonding. On the other hand, there will be new […]

Adhesive Applications in Component Manufacturing

The use of adhesives in component manufacturing ranges from automotive headlamps to plastic body components (e. g., hoods, tailgates) to interior fittings to cabriolet soft tops, including a wide range of adhesives employed. Table 3 lists applications without any claim to being complete. Looking at the plastic components it is obvious that there are many […]

Adhesive and Sealant Applications in the Assembly Shop

There are lots of adhesive applications in the assembly shop and in the manufacture of components. A complete list is not given, but adhesive use is illustrated by examples. The larger quantities of adhesives used on the assembly line are for bonding of insulation pads, interior fittings, instrument panels, and roof modules, and for direct […]

Adhesives and Sealants in the Paint Shop

Apart from underbody coating (usually PVC based), which is not explained further, the majority of bonding and sealing products in the paint shop are also PVC compounds. Acrylate plastisols are not often used and polyurethane-based sealants are rarely found. The main applications are in seam sealing and antiflutter bonding. On a small scale there are […]

Adhesive Applications in the Body Shop

There are adhesives and sealants in the body shop with basically four different functions (Table 2): 1. Sealants for body joints 2. Spot-welding sealants and tapes Figure 3 Application of a sealant automatically extruded onto an oil pan flange. Table 2 Main Adhesive Bonding and Sealing Applications in the Body Shop Application Shear strength range […]

Adhesives for Mechanical Applications

In this range of applications, adhesives are used for fastener locking, formed-in-place gaskets, and bonding of mechanical parts. Mainly cyanoacrylates, anaerobic and encap­sulated adhesives, modified acrylates, and elastomer or resin-based compounds are applied. Examples of applications are listed in Table 1. To choose a suitable adhesive, the required strength and mechanical properties as well as […]

II. ADHESIVE APPLICATIONS IN THE AUTOMOTIVE INDUSTRY

In this chapter, adhesive bonding and sealing in automobile production are subdivided schematically into five ranges of application: (1) mechanical parts production, (2) the body shop, (3) the paint shop, (4) the assembly shop, and (5) the manufacturing of components. Depending on the variety of applications, adhesives must satisfy a wide range of require­ments. On […]

Adhesives in the Automotive Industry

Eckhard H. Cordes Mercedes-Benz AG, Bremen, Germany I. INTRODUCTION Adhesive bonding and sealing are used for various applications in the modern automotive industry, ranging from flexible car body sealings to high-performance structural adhesives (Fig. 1). Adhesive types with specific properties are available for miscellaneous processing. The requirements for adhesive bonds have increased due to the […]

CONCLUSIONS

The foremost objective of operative dentistry is the durable placement of restoratives and the seating of restorations and prosthetic appliances with minimal loss of healthy tooth Abbreviation Bis-GMA Bis-MA Bis-PMA PMDM BPDM substance. With the realization that adhesion technology can be a powerful ally in this endeavor, advanced bonding techniques have in recent years been […]

Bonding Agents

One of the most intensely pursued objectives in dental materials research over the past three decades is the achievement of clinically acceptable retention, by micromechanical and/or chemical bonding mechanisms, of the restorative to the prepared enamel and dentinal tooth structure. Perfect retention, in addition to providing a major contribution to the longevity of the restoration, […]
