Gluecom is proud to announce that our high-performance J4XL wood adhesive has officially achieved D3 certification under the EN 204:2016-08 standards, as verified by ift Rosenheim – the renowned German testing institute. This prestigious D3 certified wood adhesive status highlights our ongoing commitment to superior quality, innovation, and reliability in bonding solutions.

What Is D3 Certified Wood Adhesive?

The D3 classification in the EN 204 standard confirms that the adhesive is ideal for:

• Interior environments with frequent, short-term exposure to water or condensation
• Interior spaces with high ambient humidity
• Protected exterior applications where adhesives are shielded from direct weather exposure

To earn D3 certification, adhesives must undergo rigorous testing that mimics real-world moisture and climate conditions.

J4XL Outperforms D3 Certification Requirements

J4XL didn’t just meet the certification requirements – it outperformed them with substantial safety margins. The adhesive was subjected to three challenging test sequences, with the following standout results:

• Standard Conditions (7 Days):
  Achieved an adhesive strength of 12.1 N/mm², exceeding the 10 N/mm² threshold by 21%
• Water Immersion (4 Days):
  Maintained a strength of 2.8 N/mm², outperforming the 2 N/mm² minimum by 40%
• Redrying After Immersion:
  Reached 10.8 N/mm², surpassing the 8 N/mm² requirement by 35%

These figures confirm that J4XL is a D3 certified wood glue you can rely on – even in moisture-prone or high-humidity environments.

Why Verified Certification Matters

All of Gluecom’s D3-grade products align with EN 204 standards, but official certification of J4XL provides third-party assurance, adding a layer of trust for professionals who demand documentation and proven performance.

If your project requires certified D3 wood adhesives with traceable quality, J4XL now offers the perfect combination of compliance and excellence.
