Our sign adhesives offer you versatile, convenient and durable solutions for your sign assembly needs. Build signs using structural adhesives and elminate welding, riveting and mechanical fasteners. We have a wide range of sign adhesives to select from and even some UL approved adhesives.
LORD Structural Adhesives are full performance sign adhesives that offer advantages over welding and mechanical fastening. Our sign adhesives bond dissimilar materials, provide improved appearance, insulate against galvanic corrosion and offer excellent environmental resistance. Adhesive bonding provides cost savings due to reduced labor costs and sign assembly time.
Signlok sign adhesives provide right-sized packaging to fit most jobs and eliminate waste, are UL approved, and have long shelf life options that reduces costs.
With more than 30 years of sign application experience, we have developed an extensive line of UL approved adhesive solutions that can bond multiple substrates. See our full list of UL approved adhesives and cooresponding substrates.
Thousands of signs have been built using our LORD and Signlok sign adhesives. Here are just a few sign shops that have used our adhesives.
"We do extensive real-world testing before we can trust an adhesive to perform up to our expectations and standards in our sign fabrication applications. Your products work!"
"Precise control of the the mixing and placement of the adhesive. It's dry times are accurate and bonding various mixed media is something we depend on. Always secure and effective."
"Best adhesive ever. Use it all day, everyday.
