Formaldehyde

GreenBond™ E-0 is a binder totally free of formaldehyde!

This is a “NAF” glue (No Added Formaldehyde), which is completely “E0”, which means that the formaldehyde content of the produced wood-based materials with the adhesive corresponds to the formaldehyde content of the natural wood.

Test results for GreenBond™ P2: 

Certificate issued by the Wood Research Institute in Poznan in the chamber process = 0,008 ppm,

Certificate issued by the WKI Institute in Brunswick in the chamber process = 0,007 ppm.

Results for GreenBond™ P3:

Research conducted in 2017 at the Institute of Wood Technology in Poznan

While the Board # 1, i.e. plain thick wood fibers without any glue in the board (without static function), displayed measurement values slightly above the E1 range, which is evidently due to the natural emission of formaldehyde due to pure thermal effects in the production process on pure wood fibers, the results of trials 2 and 3, prove a significant “blocking action” of the GreenBond™ binding agent.

The adhesive has properties that bind formaldehyde emissions from natural wood emissions. 

GreenBond™ is not only completely formaldehyde free, but additionally able to bind chemically formaldehyde which would otherwise get into the board, e.g. due to the proportional use of recycled wood in the normal board production process.

Thanks to good miscibility with urea resins, the proportional use of GreenBond™ adhesives in traditional formaldehyde adhesives reduces the total emissions.

VOC values

Volatile Organic Compounds (VOCs) is a term used to describe all organic substances containing carbon, which can be present also at low temperatures, e.g. at room temperature, as gases and thus are volatile. Apart from odoriferous aspects in individual cases, certain dangerous properties may also be associated with them, such as flammability, irritancy, as well as toxicity and carcinogenic and mutagenic properties and harmfulness to reproduction.

In view of the overall increase in allergy cases and the corresponding increase in the number of health-related activities undertaken by the public, as well as the consumer’s expectation that their external environment (flat, home, workplace) will be free of poisonous and carcinogenic agents, ever more important becomes the expectation of the lowest possible VOC emissions from furniture and construction products.

The following emissions were calculated for GreenBond™ E-0.

MDF / HDF board with 8% binder content (solids relative to dry wood)

VOC study at the Wood Technology Institute in Poznan, No. 350-BOS / 2017 of 16.06.2017.

C3 Limit values [sum of all volatile organic compounds] : <10 mg/m after 3 days in the chamber and TVOC28: <1 mg/m after 28 days in the chamber.

REACH regulation on workplace limit values (AGW, MAK), emissions from equipment in accordance with the technical instructions on air quality maintenance (TA)

Regulation (EC) No 1907/2006 (REACH) entered into force on 1 June 2007. REACH means Registration, Evaluation, Authorization and Restriction of Chemicals. REACH as the EU regulation, is equally applicable in all Member States. Thanks to REACH, the previous law on chemicals has been substantially harmonized and simplified. In addition, it replaced various provisions, such as the EU “Nickel Directive”.

More specifically, it should be noted here that the entire GreenBond™ family of adhesives meets all REACH requirements since no raw materials classified as harmful are used in the manufacture of GreenBond™ adhesives.

The aggregate value of the mass concentration of organic substances which can be released into the environment from production facilities as exhaust air is currently limited to first class substances up to 20 ppm (20 mg/m), and for carcinogenic substances up to 1 mg/m.

Since formaldehyde has been classified as “carcinogenic”, the limit value of 1 mg / m was recently applied to formaldehyde emissions in industrial exhaust air with effect from 17 August 2017 (REACH Regulation).

SESTEC© binders are completely formaldehyde-free, what’s more they even bind formaldehyde, which can further reduce the emissions of formaldehyde from other components and raw materials of wood-based products. With the use of SESTEC© binders it is possible to reduce the emissions of the wood processing plant to a total of 0, i.e. <1 mg / m, as required by the legislator.

Last but not least, it should be mentioned that the use of GreenBond™ adhesives from the SESTEC© Group does not infringe any labor protection regulations. The maximum concentrations in the workplace required by the legislator, the so-called “MAK” values are easily observed during the production of boards using the SESTEC©GreenBond™ adhesives.
