ABOUT US

About EIE

Epunion International Enterprise (EIE) specialises in developing innovative surface finishing chemical solutions. Our Head Office and R&D Centre is located within the Thailand Eastern Economic Corridor (EEC) in the Chonburi province. We also have a sales office located in heart of Shanghai. Our team of engineers are always exploring new concepts and trends to develop truly unique chemical processes.

We prioritize the importance of our end-users, and that is why we also have a strong distribution and technical support network that spans across a muliple of countries within the Asia region.

Our Slogan: Finishing First

This phrase holds two messages. Firstly, it describes the priority of surface finishing to us, hence “Finishing First” Secondly, it reminds us to stay competitive by "Finishing First".

Origin of epunion

The brand epunion was created in 1983 by Mr. Jyh-Rong Liang as a Portmanteau word short for "Electroplating Union".

The logo is also designed as an ambigram. Which means when flipped upside down, it reads: uoiun-da, which in Chinese reads: 遠大 (Far & Big). The use of this ambigram is to remind us not to lose sight of aiming far and dreaming big.

Throughout the years, epunion products were produced and marketed by our local partner in Thailand, but as the brand recognition started to grow, we knew we had to start a new company to manage the future growth of this brand.

In 2016 we founded Epunion International Enterprise (EIE) to be more focused on developing competitive and environmentally-friendly products for the surface finishing industry.
Our Mission

Our mission is to have a positive impact on the markets with our finishing touch.

To do so, there are many ways to achieve this. However, we hope to focus on environmentally-friendly processes that can offer an inherent advantage over traditional products. This is what we call the ECO-MEKKI development philosophy.
Our R&D Philosophy

ECOMEKKI is our R&D philosophy. ECO is an acronym for Environmental Chemistry Optimization. As chemical makers, it is responsibility to develop environmentally-friendly solutions. Not only because we want to have a positive impact on our industry, but also, we believe in working attracting customers with a high corporate social responsibility.

The word MEKKI, comes from “electroplating” in Japanese. It is a nod to our electroplating origin. As we explore other areas of surface finishing, we should not lose focus on our core business..

During our product development cycle, we need to evaluate the purpose behind developing any product by evaluating these 6 advantages:
- Reduction of overall energy consumption
- Reduction of overall water consumption and effluents
- Reduction of total cost for the user
- Reduction of chemical consumption
- Superior performance
- Future regulation compliant
The more points we can fulfill, the higher on the ECOMEKKI list it is. By implementing this thought process, we can stay true to our Mission.

Nanomono Top Coat Series

Nanomono Top Coat Series

A series of nano-ceramic and electrophoretic top coats that can achieve an unparalleled appearance, uniformity, and corrosion resistance. When used with our Spinano machine or with our Closed-loop Ultrafiltration unit, the chemical consumption of this process can be controlled to a very low volume. More importantly it also produces very little waste and contains no SoHC making it a very environmentally friendly process.
Trilux Cobalt - Free Trivalent
Passivation

Trilux Cobalt - Free Trivalent Passivation

The demand for a cobalt-free trivalent chrome passivation is on the rise for two reasons: The cost of cobalt is unstable, cobalt is on the watch list of substances of hazardous concern for REACH in Europe. Our Trilux µ83 is truly a cobalt-free system without any compromise. It is a single component product that many customers have chosen to adopt not because it is cobalt-free but because it is just a very solid product.
Chrome Free Passivation

Chrome Free Passivation

Arguably, the future of passivation will become Chrome-free. In most cases, the applicator will have to give up some practicality or performance when changing to a chrome-free system. However, we have found several ways to adapt to a chrome-free system, without compromising product performance. For example, it is very easy to combine our chrome-free passivation with Nanomono top-coats to produce a finish that has a very clean environmental footprint, but also, one that will match, if not out-perform, the traditional solutions. For more information about our chrome-free systems, please contact us directly.
Spinano 400DS

Spinano 400DS

The Spinano machine when used in conjuncture with our nanomono sealants is able to achieve an unparalleled finsih.
Both the appearance and corrosion resistance will be upgraded after this process.
lt is also possible to adjust the coefficient of friction to suit the requirements of the user.

The machine has a Programmable Logic Controller that allows the adjustment of many variables such as the rotation speed, cycle time, chemical dose rate, and tilt angle.
Typically 1kg of sealant can be used to coat 500kg of fasteners (size M8) with a thickness of around 1 to 3 microns.
