Lord’s Sign Bond Series – A Guide to Choosing the Right Sign Adhesive
Lord Corporation has long been driving the sign industry adhesives market with a special affinity and focus for technologically advanced signage products that can hold and endure in pretty unforgiving environments. That’s why, as a preferred distributor for Lord, we at Chemical Concepts point to Lord’s quiver of top quality sign industry adhesives whenever a professional inquires. In this blog, we’ll differentiate between a few of Lord’s best, and detail which product to use in which instance.
The 400 Series
In situations that require metal bonding and the cross bonding of metals to plastics or similar materials, the 400 Series from Lord is the ticket. This series is considered to be the most versatile of the group, and can practically replace welding, riveting, brazing and other mechanical means for fastening, and can and will often outperform them in tough environments. This class includes the following 400 Series products:
These three metal bonding adhesives are separate and distinct due to their speed, or their quickness in arriving at work and handling time; the 403 is the fastest, achieving work time in as soon as two minutes and handling time in as little as four minutes. The 410 is the slowest, and the 406 serves as the intermediate choice.
Typical Applications
- Bare Metals – Aluminum, Steel, Stainless Steel
- Painted Metals
- Acrylic Sheets
- Vinyl Laminates
- Polycarbonate Sheets
- Polystyrene Boards
…and more
The 7500 Series
The 7500 series is best suited for plastic bonding and the cross bonding of an assortment of plastics. Used frequently for optically clear applications, gap filling, and bonding wood, the 7500 series is tough, flexible, and like its 400 series counterpart, available in three different speeds.
The 7550 A/C, the preferred industry choice for bonding trimcap materials to polycarbonate faces, is the fastest, with a working time range of 2-4 minutes and a handline time of 4-6 minutes. The 7542 A/B is the medium choice and the 7542 A/D is the slowest of the bunch, requiring 1-2 hours before handling.
Typical Applications
- Paper/Foam Boards
- PETG Sheets
- Acrylic Sheets
- Wood
- High Density Urethane Boards
…and more
No-Mix Series
The No-Mix series from Lord is the go-to for large surfaces with tight tolerances, like mounting a sign face. The products in this class have an indefinite speed time, meaning that curing does not start until both parts of the assembly are brought together – this is an especially ideal characteristic for large applications of metals and similar surfaces. No-mix series adhesives must be applied to opposite mating surfaces to be bonded. Lord’s No-Mix series includes the following products:
*Each No-Mix product should be used in combination with Lord Accelerator 4.
Typical Applications
- Bare Metals
- Aluminum Composite Panels
- High Density Surfaces
- Expanded PVC Foam Board
…and more
Signlok Series
The Lord Signlok series is the perfect option when it comes to structural adhesives. These include:
Lord Signlok 810 is great for bonding thin gauge metal materials with no bond-line read-through or surface distortion. Features include 90% full cure within one hour, minimal surface preparation, and two mixing tips included with each purchase.
The Lord Signlok 400 series offer versatile, durable, and convenient solutions that can replace welds, rivets and other mechanical fastening methods. Features include an 18 month shelf life, a range of work times to accommodate your process requirements, and it contains glass beads to enable precision bond-line control to help manage waste.
We certainly hope that this has been a helpful guide in choosing the right Lord sign adhesive for your job! If you have any questions, please don’t hesitate to contact our team!
