Spray Adhesives – Use & Application

http://www.ok2spray.com/wt-hs13.php

Demands of packaged spray adhesives have been growing in the market considerably owing to the growing industrial development in the manufacturing sector. These are user friendly products that are convenient to use whenever the applications of adhesives are required. These adhesives are easier to apply without dirtying or messing up the surface of application and obtaining a clean and finished surface serving the purpose for which this product is intended for. Effective Use

Spray adhesives are effective glues as they properly wet the base of the joining surfaces and transmit the load between the merged surfaces uniformly to get better and stronger bonding. Because of advances made in branches of chemical technology like polymers, the quality and usability of the adhesives have enhanced considerably creating more and more demand and boost to the adhesive

industry.

There are a range of surfaces where these adhesives can be effectively used like paper, wood, fabrics, glass, films, leather, foil, plastics, cardboard, canvas and many other planes where its application is required. Its quick drying quality and ease for repositioning, if required, during the process of application makes it an easy-to-use item. Preparation for Application

The application of spray adhesives need to be proper for a better bonding and to have a clean and superior finish of the surface. An open and well ventilated work area is required for applying the adhesives so that fumes from the spray are properly circulated and not constrained in an area which can cause harm and be unhealthy. Persons who are involved in applying the adhesives must use facial or nose masks to prevent inhaling of the fumes and gloves, preferably latex as they are non-sticky types for protection at the time of application.

Precaution must be taken to prepare a protective surface by using cardboard, cloth or newspaper to cover and protect the base surface. Safety instructions and method of use of these adhesives given on the product or the pamphlet of the manufacturer should be followed for safety and better results. Application of Adhesives

The surface of the items that are required to be bonded should be cleaned of any dirt, oil, moisture for a good fusion. While spraying the adhesive over the surface of the item, it should be sprayed uniformly so that the surfaces are stuck in an even and smooth manner. If at all a second round of spraying is required for attaining uniformity in application, it should be done faster as lapse of more time will dry the adhesive leading to its ineffectiveness. Too much spraying or too less spraying of the adhesives will produce an uneven joint and an inferior bonding of the surfaces.

Steps After Application

Observe that enough time is lapsed after spraying the adhesive as mentioned in the manual / pamphlet of the product before the surfaces are secured and pressed in a uniform manner. Ensure that the pieces are aligned properly and care should be taken not to move the pieces disjointedly to restrain the pieces from getting glued wrongly. Bubbles, if any, between the surfaces should be

removed by applying pressure to obtain an even surface finish. Proper cleaning of the surfaces of any overspray should be done immediately to prevent the glue from getting dried on the open surfaces. There are adhesive removers available for any hard to remove stains.

Conclusion

The degree of adhesiveness of different materials depends upon the chemical composition of the

adhesives and spray adhesives are made taking this factor into consideration. Spray adhesive are specifically designed to provide permanent bonding of materials for a variety of applications. Bonds (HPL) plastic laminates to wood or particleboard, Radius edgebanding, Upholstery to metal and

Automotive headliners are some of its use in the industry. For More Information : http://www.ok2spray.com/wt-hs13.php
