Enviromently friendly: the close-up

Therefore, to sum up, it is possible to state that the whole technical advantages (low
viscosity, high quickness, excellent adhesion and light resistance) and the benefits
derived from the lack of labelling with hazard symbols are the starting point of the
diffusion of MS-Polymer based products, able to solve a wide range of application


When looking at this study it is clear that bearing no hazard on the label does not safeguard you from hazards. One of the biggest, and nearly only, hazards of MS Polymer adhesives is methanol. The curing mechanism of these types of adhesives take moisture from the air to cure and release methanol as end product.

This study further shows that the amount of methanol released is much higher than expected. What this study does is simulate a typical installation of flooring. These results are astonishingly bad. This study shows that after 5 minutes the maximum for 15 minutes is exceeded more than 2 times. This continues to be more than allowed trough the whole test set-up.

This appears to be strange at first there are some simple reasons for this. The most important reason is that they didn’t “use the adhesive in a well ventilated room”. This to simulate the way a professional would install when time is limited.

Blue Angel – Eco-Label with Brand Character

The Blue Angel is the first and oldest environment-related label for products and services in the world.


When concidering enviromental benefits there are a lot of  choices you can go for,  to prove your product is enviromentally better than the compeditors.

The oldest of these ecolabels within the EU is founded in germany.  Blue Angel is an initiative of the Federal Minister of Interior and approved by the Ministers of the Environment of the federal government.

Being the oldest eco-label available  it has already put its mark on a lot of oncoming laws in the field of climat change. One of the succes stories is the recyclage of old paper. By awarding a label for recycled paper it helped give live to the recycle industrie.  This is helped by politicians promoting recycled paper by using it in their public offices.

With EMICODE®, you’re always on the safe side


One of the important types of labeling for adhesives is  EMICODE. When a product passes EMICODE EC1 Plus standards it is tought to be safe for the everyday installer to use. This means that on a daily basis the amount of toxic substances released should be lower than the amount legally declared. This assumes that the installer takes all precautions necessary

The main part for passing EMICODE tests is the amount of  Volatile organic compound or VOC. The most common types of VOC coming from adhesives are types of alcohol and formaldehyde.  This is measured precisely on different times after applying the adhesive. This is after 1 – 3 and 28 days. This is done by taking air out of the testchamber and measuring it for organic substances in a GC.

Another part for passing EMICODE testing is no use of carcinogenic or deemed toxic or very toxic by law.

There are no legal implications for following or not following this standard, although it is generally followed to keep up with competing company’s.

new in the global clas: GHS/CLP

We gebruiken elke dag wel chemische producten bij onze dagelijkse taken zoals schoonmaken, ontkalken, schilderen, verlijmen, oliën of invetten. Maar hoewel deze hulpmiddeltjes natuurlijk heel welkom zijn, is het gebruik ervan niet zonder gevaar …


With enviroment and safety for chemical substances is a world wide concern, politcians gathered for an ambitious project.

The Globally Harmonized System for Classification , Labelling and Packaging of chemicals or GHS/CLP in short was introduced to

make an uniform way to indentify chemicals.

Although it was a big step in the good direction it didn’t work as good as planned.

From 1 december 2010 the rules became more global altough each region still has it’s own nuances.

The main differences from the previous system are other, more global understood messages and

the adaptation of H- and P sentenses instead of R- and S-sentences.

The infograph below discribes the biggest differences

What makes our clock tick : REACh legislation

‘The former EC legislative framework for chemical substances was a patchwork of many different Directives and Regulations’

‘This system did not produce sufficient information about
the effects of the majority of existing chemicals on human health and the environment.’

‘Since 1993, only 141 high-volume chemicals
were identified as priority substances for risk assessment’


When looking at the legislation that is protecting us, it has many different levels. The top-level relevant for us as belgium citizen is the European level. To protect the environment and the citizens of Europa, there is more than 40 years of guidelines and pacts being made.

Because of historical background these legislations started with country’s in charge of testing which chemicals should be considered dangerous. It proved to be to hard for much country’s to keep up with the speed of  development. This lead to a huge safety risk which much policy makers wouldn’t want to stand for.

To counter this REACh was put in place. The meaning of REACh is  Registration, Evaluation, Authorisation and Restriction of Chemical substances. What this actually means is that there has been a shift in responsibility. Before it was a country’s responsibility to prove a product was unhealthy or unsafe, as for now each producer has to register his products in a central database, and prove it does not harm man and nature more than it’s competitors products  does.

This law has only been in place since 1 June 2007

REACh : intro

What exactly is cross-platform?

Like said before, Qt Creator is a cross-platform IDE (Integrated Development Environment). But what exactly does that mean. Cross-platform actually just means platform independent and a platform should be interpreted as an operating system. In essence, most popular programming language like c, c++ ,c# or java are cross-platform. Java is bit a stranger in this list. Java itself actually runs only on the Java Virtual Machine, but this virtual machine runs on most platforms.
So simple compiled c or c++ code will run on multiple platforms but every decent application will need to do some interaction with the OS (operating system) for showing the GUI as example. These interactions differ from OS to OS, so a choice has to be made for which OS an application is developed.  If you would ask somebody eight years ago an IDE to develop an application most heard answer was probably Visual Studio. It’s an IDE to develop applications for Windows. It was a logic choice considering more than 95% of pc users was a Windows user[1]. Nowadays this share almost decreased to 85%  and with the prospect that Apple might become the largest computer manufacturer of 2012 this share will continue to decrease[2]. So it might be interesting to use a cross-platform IDE like QT Creator. QT Creator exists in a version for Windows, Linux and Mac OS X. Not only QT Creator itself is cross-platform, but also your projects made in QT Creator are Cross-platform. An application made in QT Creator for Mac OS X can be compiled to run on a windows machine or Mac OS X without even changing one line of code. This is called cross compiling.

This sounds off course very interesting, without any extra effort your application runs on multiple platforms. But it’s not all roses, let’s see next time why we all don’t use a cross-platform IDE.

Prosthesis and Total hip arthroplasty (THA)

In medicine, a prosthesis is an artificial device extension that replaces a missing body part.

It is part of the field of biomechatronics, the science of using mechanicaldevices with human muscle,

skeleton, and nervous systems to assist or enhance motor control lost by trauma, disease, ordefect.

Prostheses are typically used to replace parts lost by injury (traumatic) or missing from birth (congenital)

or to supplement defective body parts.

Particularly, hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic

implant. In total hip arthroplasty (THA), the inside of a femur has to be removed and an

 implant/prosthesis will be inserted into the cavity either cemented or without cement.
