Increasing alternatives to mechanical fastening are available.
September 1, 2004
With ongoing advances in structural adhesive formulation, designers in every industry have increasing alternatives to mechanical fasteners for assembly of metal, composites, plastics, rubber, glass and more.
Every single design consideration—including the adhesives selected—is important in the costly endeavor to send an object into space.

The harsh conditions of space place a set of constraints on the technologies that take us there. Of primary concern when it comes to space system design is the adhesive chosen to hold everything together. What does it take to perform in the vacuum of space, and why do silicone adhesives continue to be the adhesive of choice in many aerospace applications?
Water-based adhesive systems make inroads into traditional solventborne technology.

Contact adhesives based on polychloroprene exhibit performance advantages over alternative adhesive systems in a variety of related applications where quick, high-strength, permanent bonds are needed.
Analytical tools are now available to engineers and product designers challenged with the task of reducing the radiated noise and vibration levels of structures.
The radiated noise and vibration characteristics of manufactured goods are a common concern for most product designers as they strive to provide products that are "whisper quiet."
Standards are an important aspect of your business. If you manufacture, purchase, or use sealants or if you supply raw materials for sealants, your company relies on standards every day. R&D uses test methods and specifications to characterize, compare and develop products. Marketing and Sales use these same standards to advertise and promote products. When materials or sealants are purchased, they must comply with specifications.
To answer our questions on the outlook for the industry, we leaned on members of our editorial advisory board and others representing raw material and equipment suppliers, adhesives manufacturing, product development, technical service, business management and consulting.
Tap into the expertise of an impressive group of professionals specializing in adhesives and sealants, ask them to predict the future for the industry, spice it up with their opinions on some hot topics, and you come up with a good read.
Poly bd resins are used in adhesives, sealants, castable elastomers, caulks, membranes, foams, coatings, propellant binders, potting and encapsulating compounds, as well as other rubber-fabricated materials.

Poly bd resins, from Elf Atochem North America Inc., Philadelphia, are liquid, hydroxyl-terminated homopolymers of butadiene. The facile reaction of Poly bd resins with curing agents such as conventional di- and polyisocyanates provides an economical route to the preparation of general-purpose elastomers. The unique structure of these resins provides properties that surpass conventional polyether and polyester urethane systems, as well as conventional, general-purpose rubbers.
ISO 9000 has been revised—but the new standard, called ISO 9000:2000, is a radical revision and the industry has questions.
April 17, 2000
In view of the impact of this revision and the costs it will entail, organizations understandably have many questions and concerns. Do we have to register to the new standard? How long is our current certification good for? Why the change? What’s the difference between the old ISO and the new ISO? How will it change the way we run our business? Who will benefit from the new standard? Who will be hurt? Will it be more difficult to implement the new ISO than the old ISO?
