Computer programs adhesive selection

Lees, W. A. (1984) Adhesives in Engineering Design, Design Council, London. (A companion computer-aided adhesives selection program for an Apple, BBC and IBM microcomputer is also available.)... 

In most cases, the ability of the adhesive to support the design loads under service conditions for the planned life of the structure is considered first. Thus the mechanical properties, durability, and environmental resistance of the bonded structure are of obvious importance. But of equal concern are the nature of the adherends, the application technique, the cure conditions, the handling requirements, and, perhaps, the cost. A list of some of the factors considered in the selection process, together with the properties of the major generic classes of adhesives, are given in Table VI." It is important to remember that, even within a given class of adhesives, the performance may vary considerably, so that it is essential to consider the properties of each individual adhesive. It is apparent from this brief discussion that adhesive selection is far from simple. A computer-based selection program has become available recently." ... 

Computer-based Adhesive Selector Guides are now becoming available. Such programs aim to assist the adhesive selection process, taking into account the joint design and requirements. The programs often take the form of an on-screen questionnaire describing the application and any particular requirements. This information is then used to search a product database and list adhesives which meet the requirements. 

Jet dispensing, also known as jetting, is a direct-dispensing process whereby the adhesive paste is forced through a fine nozzle and programmed to flow onto selected areas controlled from a computer database. It is an automated method that differs from syringe/needle dispensing in that contact with the surface is not required to produce the dots, lines, or patterns.
