The Introduction of A Resin Sign

The Introduction of A Resin Sign


A resin sign is composed of three parts: the outer shell, filling material, and the light source. The outer shell part is made of plastic (ABS) injection molding or metal sheet (stainless steel, aluminum, etc.); the filling material is the liquid resin which can produce transmission, refraction, and reflection, achieving the good diffusion effects. In this way, the light can keep brightness and uniformity when it goes through the resin.

The Making Process of The Custom Resin Signs

Custom resin signs consist of a base liquid, an activator that starts the curing process, diffuser agent to evenly distribute the LED light and color pigment. 

Mixing resin can be likened to the painting process, with different colors added to achieve a specific shade. Colors are available in standard and Pantone-matched variants. Often there is a compromise that needs to take place between the Pantone colors, where the desired color is achieved either when the lights are on or off. The use of color LEDs is advantageous to achieve specific color finishes.

The inside of resin sign letters is spray painted bright white to maximize the reflection of LED lights. Once the paint has dried, the LED’s are fixed to the inside of the letter shell. The lights are then connected to terminals and in turn the power supply unit.

A 1mm to 2mm clear lid is then positioned inside the ‘letter shell’, leaving a recess from the top of the letter, this is sealed with specialized glue to ensure it is water-tight so when the liquid resin is poured over it, it does not leak. The prepared liquid resin mix is then poured into a stainless steel or aluminum ‘letter shell’, which have been micro welded or joined together and then polished or painted according to customer requirements. The resin is poured on top of the  will create a raised surface.

Resin variants include flat-face or domed-face and matte or gloss. There are 4 hour and 12 hour curing variations. Environmental conditions inside a workshop play a big part in the curing process of a resin sign.

Why A Resin Sign Plays An Important Role in Advertisement?

Custom resin signs for business are some of the most important elements of advertising because they allow consumers to identify an image with a brand, product or business. If consumers don’t remember a brand or product, the chances of them buying that brand or product decrease significantly. Signs and billboards build brand equity in the minds of consumers, making them more likely to buy a product because they remember it.


Consumers are more likely to buy a product they have seen before or have heard about than a product they’ve never heard of. After seeing a resin sign, a consumer is more likely to remember that brand or product the next time he sees it. This is called recognition and is a major goal of all advertising.


A sign simply creates another touchpoint with a consumer. Touchpoints occur at any time a consumer comes in contact with a brand or product. A company wants all touchpoints to be positive so that consumers will not only remember a brand or product but remember it in a positive light.

Call to Action

Many outdoor billboard custom resin signs are used to call a consumer to action or ask the consumer directly to consider buying a product. A resin sign might advertise a sale or a recent development in a product that a consumer might find interesting, so a sign can be effective in directing a consumer to a store.


Since a sign doesn’t have to be near a company or business doing the selling, a sign can pull more people to that business from other areas. If a sign is in a location away from the actual store or business, consumers that might not know about that business will have a better chance of finding out about it.
