|There are numerous types of locators used throughout the sign industry, and these are used to secure signs manufactured from a wide range of materials.
Metal locators are by far the most practical to use, in conjunction with an adhesive, as the bases are perforated to allow the adhesive to flow through and encapulate the locator.
These come in all different shapes, sizes, and metal compounds, but thankfully the appliction process remains the same.
For Mild Steel locators we would recommend our SignFix 7 adhesive, for most sign materials where aesthetics allow. For Aluminium Composite we would strongly recommned the SignFix 8, to prevent the risk of witness marks on the face of the sign.
Brass locators do seem to be a popular choice at the moment, however, take care when bonding brass parts. Preparation of the material is key to achieving the maximum level of adhesion.
Due to its oxidising properties, you must abrade clean, prime and bond in quick succession. A delay in the process would allow the surface to oxidise, which could prove troublesome when applying the glue.
Brass also expands and contracts at a different rate to other metals, which could cause brittle adhesives to break.
For brass locators we would recommend SignFix 18, as this adhesive meets the high demands of the material.
