Increasing interest in surface mount technology has led to a growth in the use of adhesives for attachment of SMDs. This paper reviews the properties of an adhesive which make it suitable for use in attachment of SMDs. Visibility, rheology and cure speed are of primary importance but the need for one‐part stable materials is stressed. The existing adhesives offered are generally based on epoxy or acrylic technology. Though these products are effective in attachment they have many features which make them less than ideal, e.g., mixing of multi‐component systems, high cure temperature, etc. One‐part acrylic anaerobic adhesives offer the benefit of low cure temperatures with good strength and product stability. Curing data, adhesive properties and cured polymer properties are reported for a new acrylic anaerobic adhesive which has been specifically designed for attachment of SMDs to substrates.

A Review of the Properties and Applications of High‐Strength Metal‐to‐Metal Joints and Sandwich Constructions Bonded with High‐Strength Adhesives. TODAY'S adhesives are the complex products of continually expanding technologies. Their applications appear to be limited only by the skill and ingenuity of the designer and his fabricators. Even in a single area such as metal‐to‐metal bonds in aerospace and electronic uses, evaluation and selection of an adhesive requires familiarity with a large number of adhesive systems.

As an important part of steel bridge deck pavement, if waterproof adhesive layer performance does not meet requirements, numerous kinds of bridge deck pavement distress may be encountered. To study the adhesive behavior of rubber asphalt waterproof adhesive layers in steel bridge gussasphalt pavement, the pull-off and direct-shear tests have been used in the study to mechanically simulate steel bridge deck pavement under vehicles loading.

Several potentially influential factors associated with the adhesive strength of rubber asphalt are investigated including temperature, spraying quantity and environmental conditions.

Results indicate that rubber asphalt was associated with good performance with respect to its use as a waterproof adhesive layer; simulated performance was negatively correlated with increasing temperatures. A necessary spraying quantity of 0.4 Lm^-2 is required for appropriate adhesive strength of the composite structure, with a decrease in adhesive strength noted when spraying quantity is significantly greater or less than this.

The current paper presents an examination of the adhesive performance of a rubber asphalt adhesive layer on steel bridge deck pouring construction, while additionally examining potentially influential factors and conditions via use of both pull-off and shear tests.

Looks at the increasing pressure from both environmental and health and safety aspects to overcome the problems associated with solvent‐based adhesives and comply with current and proposed legislation. Discusses the four basic solutions of using solvent containment, safe and environmentally‐friendly solvents, high solids systems and solvent‐free adhesives. Concludes that the long‐term option is solvent‐free systems such as water based, hot‐melt and liquid reactive adhesives, but substantial advances in technology are required if they are to make major inroads in the solvent‐based adhesive market.

Discusses the use of piperylene‐styrene copolymer (PSC) for polychloroprene adhesive modification. States that PSC significantly improves modified adhesive properties ‐ bond strength, viscosity, high heat resistance, good adhesion to a variety of substrates, compatibility with other adhesive additives. Looks at the advantage of using more environmentally friendly technology for thermoplastic rubber bonding with PSC modified polychloroprene adhesives. Concludes that the new adhesive product can be used for specific combinations of materials and application methods, making it possible to produce cheaper and better products.

The purpose of this paper is to study the bonding properties of Larch with water‐based polymer isocynate (WPI) adhesive to provide theoretical instruction for practical production of Larch glued laminated timber with WPI adhesive.

This study adopted Japanese JIS K6806 standard to test bonding properties of Larch with WPI adhesive. Scanning electron microscope was used to observe morphography of Larch surface. Micro photos were adopted to show the penetration of WPI adhesive on the radial and tangential surfaces of Larch.

There was significant difference in bonding strength between Larch radial and tangential glue‐blocks glued with WPI adhesive. Dry compressing shear strength of Larch radial glue‐block bonded with WPI adhesive was 1.41 times that of Larch tangential glue‐block bonded with WPI adhesive in normal conditions. Wood failure showed that the difference between Larch radial and tangential glue‐block was caused by wood structure of Larch itself.

The research conclusion that the dry compressing shear strength of Larch radial glue‐block bonded with WPI adhesive was bigger than that of Larch tangential glue‐block bonded in normal conditions. These would be changed if other adhesives were adopted to glue Larch wood.

The conclusion developed in this study provided a practical production instruction for Larch glued laminated timber with WPI adhesive. In order to obtain better bonding properties during the production of Larch glued laminated wood, Larch wood should be sawn into radial boards rather than tangential boards in order to obtain maximum bonding strength of Larch wood.

The paper shows that there was significant difference in bonding strength between Larch radial and tangential glue‐bonded blocks with WPI adhesive. Dry compressing shear strength of Larch radial glue‐block bonded with WPI adhesive was 1.41 times that of Larch tangential glue‐block bonded with WPI adhesive in normal conditions.

Where does the coatings industry look for technology which borders on its own and from which it might derive useful leads and ideas? The coatings industry basically depends on the formation of films. Basic to the idea of coatings is the concept that there must be a film and that this film must derive from the vehicle in the coating. To be sure, the film does not represent the entire coating, but it is the sine qua non; and without a film the coating will neither decorate nor protect. There are a host of other technologies that depend on film formation. When the word ‘film’ is mentioned, adhesives and printing inks come to mind, for these technologies also could not exist without the all‐important phenomenon of film formation.

The purpose of this paper is to research the durability of the adhesive‐poly(ethylene terephthalate) film joints.

The adhesive‐poly(ethylene terephthalate) joints are prepared with poly ethylene terephthalate film synthesised from thioglycolic acid, terpene hydrocarbon resin and acetone resolution at room temperature. These joints are characterised by methods of peel strength tests, energy dispersive X‐ray spectroscopy (EDX) and analysis of glass transition temperature (T_g) to examine their durability.

Peel strength tests and EDX analyses prove that water diffusion in different humidity aging conditions causes similar changes, namely having the time‐temperature equivalence at 45°C for 200, 300, 500 and 600 h, respectively, almost corresponding with those at 55°C for 100, 200, 300 and 400 h, respectively, and at 65°C for 50, 100, 150 and 200 h, respectively. The changes in EDX spectra of adhesive‐poly(ethylene terephthalate) film joints indicate that the rate of water penetration in the adhesive is faster than that in the poly(ethylene terephthalate) film. In humidity aging process, the decline ratio of peel strength of adhesive‐poly(ethylene terephthalate) film joints treated with Co⁶⁰ irradiation is lower than that treated with acetone washing or chemical treatment.

The paper shows that using EDX for analysis of durability of adhesive film joints is of significance to industrial process.

The purpose of this paper is to study interactions between water‐based polymer isocyanate (WPI) adhesive and bamboo by means of differential scanning calorimetry (DSC).

The method of adapting new reference substance replacing aluminium was used due to the special characteristic of WPI adhesive when studying reactions between WPI adhesive and bamboo.

The methods of changing reference substance could counteract effect of water in the sample on DSC measurement. The results of DSC analysis showed that hardener of WPI adhesive can react with water and also with ‐OH in bamboo and matrix of WPI adhesives. That is to say that a competition exists between urethane formation (covalent bonding of isocyanate with hydroxyl groups in bamboo and matrix in WPI adhesive) and urea formation (isocyanate consumption due to the reaction with water) during the operation of glued bamboo products.

The method of changing reference substance can be used for other DSC samples in which water cannot be conveniently removed, but this method requires that weight of reference substance to be exactly the same as the sample used in DSC measurement. So accuracy of weighing was very important in this DSC measurement.

The method developed in this paper provides a simple and practical solution to studying interactions between WPI adhesive and bamboo by means of DSC.

Changing reference substance was brought forward as a new method of counteracting effect of water in the sample on DSC measurement. The understanding gained through this study could help improve bonding properties of glued bamboo products.
