Fleet Graphics

Although today, many companies have fleets of service vehicles (passenger cars, transporters, trucks) which offer a huge potential for brand promotion, this approach is rarely used. Yet, by using the advertising space provided by these vehicles, whether by using a simple logo or complex graphics, it is possible to create an excellent product image. In […]

Surface Design

8.13.1 Surface Design and Surface Protection Self-adhesive films for the design or protection of surfaces are specially conceived for use on flat or uneven substrates, with or without rivets and recesses, and adjust to any unevenness without too-high a restoring force. This is achieved by careful adjust­ment of the rheology of the system, which comprises […]

License Plates

License plates, which were conceived with the birth of the automobile, began as simple color-painted plates but have rapidly evolved into high-tech car identifi­cation labels. One landmark in this development was the replacement of color painting by self-adhesive reflective sheeting (binding since 1989). Later, in 1995, European vehicle registration plate graphics were introduced (binding in […]

Pavement Markings

In the dark, 40% of roadway markings are poorly visible, while in dark and rainy conditions even the majority of markings cannot be seen. As a consequence, they will no longer serve their purpose, which is to route traffic. Pavement markings with high night-time visibility in rainy conditions definitely enhance road safety and should be […]

Traffic Signs

Traffic signs and devices must be highly visible and legible to clearly alert and inform drivers in time. High-quality traffic signs can contribute to meeting the higher road safety needs arising from a traffic volume that has drastically increased in recent years. Especially in urban traffic conditions, traffic participants are blinded or distracted by extraneous […]

Road and Highway Engineering

Within the EU, more than 40 000 lives are lost in traffic accidents each year, and some 9000 people are injured each day. Traffic accidents are the most common cause of death for those aged below 45 years, and cause more casualties than either heart disease or cancer. The financial burden is estimated at D160 […]

Footwear Industry

From the early 19th century until the Second World War, footwear was exclusively bonded with nitrocellulose solutions. Polychloroprene rubber solutions were intro­duced in about 1949, and offered the possibility of bonding chemically dissimilar materials such as rubber and synthetics. Until then, only leather had been used in footwear production, and the introduction of a new […]

Aging of RFL-Dipped Textiles

Due to the reactivity of RFL systems, RFL-dipped textiles must be stored in a cool, dark and dry place (common storage conditions for such textiles) to preserve the adhesion-promoting effect until processing. Occasionally, correctly stored textiles preserve their properties for an extraordinarily long period of more than 24 months [60]. If, however, the textiles are […]

Adhesion Mechanisms

With regards to the adhesion mechanisms involved in textile reinforcement of rubbers, a distinction must be made between adhesion at the dip/rubber interface and adhesion at the dip/textile interface. Figure 8.67 Possible condensation or addition reaction resols with latex double bonds. Adhesion at the dip/rubber interface is obtained by the direct crosslinking of dip components […]

Direct Adhesion Through Addition of the Adhesion Promoter to the Rubber Mixture

The labor-intensive dip process can be avoided when the components of the adhesive system are added directly to the rubber mixture. Highly dispersed silica is used to activate the reaction, and hexamethylenetetramine or hydroxyl methyl derivatives are employed as formaldehyde donors. The reaction between fiber and matrix takes place according to the mechanism described above. […]
