Weicon adhesive spray, strong

Applications: When gluing large areas it is often difficult to evenly distribute the adhesive everywhere before it has already begun to dry. This problem can be gotten around by using a spray glue. When evenly and thinly sprayed, it will form a coat of adhesive which will not bleed through or make paper wavy. Spray glue can be used on numerous materials: paper and cardboard, a wide variety of plastics and plastic foams (glued to themselves or on wood and metal). Typical areas of use for spray glue include mounting drawings, placards, photographs, maps and the like on solid backgrounds. Examples of substrates abound: KAPA boards, honeycomb board, thick cardboards, basic corrugated boards, Forex boards, etc.

Treatment: When mounting on smaller surfaces it is not the substrate that receives the even coat of glue but rather the object that is to be mounted. After the glue has been applied, mounting should begin on one of the short sides and the rest carefully stretched out and pressed into place. This pressing should always be done from the middle outwards as much as possible so as to avoid small bubbles forming. After that is completed, a PRESSURE ROLLER or a FELT SQUEEGEE-TYPE APPLICATOR should be employed for further flattening purposes. If, for example, you plan to glue-mount a large number of ink-jet prints on presentation boards, it is helpful to have many separate underlayers on hand because as you spray the backside of a print there will always be some overspray on the underlayer upon which you will then not be able to lay the next print.

This permanent adhesive spray is an economically priced, universal glue that is designed less for working with paper and photographs than for large area bonds on lighter weight materials usually found in workshops and handicrafts. The possible materials include cardboard, wood veneer, cork, leather, various textiles, soft foams, rubber and different types of plastic films. Our experience has shown that it can also be used to bond polystyrene rigid foam (styrofoam, styropor) – but preliminary tests should be made on the actual material you plan on using.

Please note when working with paper that the strong version of the Weicon spray adhesive will bleed through on paper that is less than 130 g/m².

The spray pattern from this version is somewhat unpredictable, which means it is not really great for use on smaller surfaces. According to the manufacturer, the contents of the can is sufficient to coat about 4 m² (depending, of course, on the type of material(s) being bonded). In comparison to the adhesive sprays from 3M, the Weicon sprays are less expensive and have a longer open time (working time), which for many jobs can be a real advantage while for others it might be a negative.
