MRC -- Wanhua Chemical Lacper 4572 is utilized in the field of outdoor wood, extending the outdoor lifespan of woodwork, said the company.
The product complies with the EU's REACH environmental regulations, free from SVHC and CMR substances. Besides, it has excellent weather resistance, moisture resistance, as well as stackability. It is widely employed in various outdoor factories and on-site construction projects. Lacper 4572 is able to maintain good adhesion and colour, despite slight glossiness loss. In comparison to other emulsions, the product shows no patchiness caused by foaming or peeling.
Lacper 4572 underwent the water absorption-freeze-thaw cycle test for 6 times, which is designed to simulate harsh outdoor conditions, showing no cracking, bubbling, or whitening. After immersion in water, it achieved the highest wet adhesion rating of 0.
Due to the stringent requirements for flexibility, outdoor applications need emulsion with low film-forming temperatures, but they may suffer from poor anti-adhesion. Wanhua Chemical is committed to balancing these two properties through a multi-layer core-shell structure design, Lacper 4572 achieves excellent film formation while reducing the amount of film-forming additives, maintaining a balance in early anti-blocking performance. This allows for the application of Lacper 4572 in fast production in factories.
QUV testing is for outdoor UV resistance, and Lacper 4572 demonstrates exceptional long-term QUV performance: at 2000 hours, Delta E is 0.44, and at 3000 hours, Delta E is 0.78. This makes Lacper 4572 suitable for wood-related applications with extreme QUV requirements.
We remind, On December 1, Wanhua Chemical’s official website released a draft environmental impact report for the project. The company will build a new 400,000 tons/year polyolefin elastomer device and supporting public auxiliary projects and auxiliary facilities in Penglai Chemical Industrial Park Wanhua Penglai Industrial Park.
