Transparent solutions for signs and signage

Signmakers (and other companies specializing in outdoor signage and advertising) produce visual communication materials for stores, hotels, and other businesses wishing to enhance their image.

Industrial adhesives, such as MMA adhesives, have been commonly used for many years by this industry sector for signage.

In addition, some letters used in storefronts are illuminated, and contain electronic components (e.g. LED ribbons) that need to be protected against water and moisture: for this, manufacturers, like the lighting industry, are used to using various MSP or silicone sealants to make their assemblies waterproof and protect the components against rain.

Nowadays, for aesthetic reasons, designers are increasingly looking for transparent products that can achieve a perfectly invisible bond.

Sign assembly process, step by step

Surface preparation:

Diestone DLS is a fast evaporating solvent mixture used for degreasing and preparing surfaces, especially aluminum and PMMA, before gluing or painting. It also allows for easy removal of excess adhesives and sealants.

Available in pre-saturated wipes, this format limits solvent consumption and reduces HSE risks (risk of flammability, reduced toxicity for operators).

Encapsulation

Electrolube polyurethane resins allow for quick and easy encapsulation of LED strips in signs to protect them from external aggressions (humidity, UV...). Non-yellowing, these resins optimize the life of LEDs.

Electrolube UR5634 is perfectly transparent to let the light through.

Electrolube UR5635 is a cloudy resin, for a homogeneous diffusion of the light.

Bonding & sealing

MMA structural adhesives are compatible with the substrates commonly used in the sign industry (aluminum, PMMA, etc.) and provide a durable, solid assembly. Proven solutions for sign making include:
