Synthomer
New formaldehyde-free polymer dispersions

09.05.2019 Due to increasing environmental awareness and tightening regulations, reducing emissions and VOCs represents one of the major trends in the textile industry. One of the world’s leading suppliers of emulsion and specialty polymers, Synthomer Deutschland GmbH, Marl/Germany, will be at the Techtextil will provide an exclusive preview of a range of new polymer dispersions specifically developed for ultra-low emissions.

Revacryl 1425, 1490, and 1610 represent a new generation of styrene-acrylic emulsions for the coating of glass fiber wall textiles, both woven and nonwoven. The self-crosslinking formula is free of formaldehyde emissions, and combines its low VOC approach with very good performance, resulting in a particularly high line speed. All 3 dispersions give a high water resistance and good compatibility with starch and zirconium-based linkers (AZC). They only vary in the haptics they provide to the glass fiber fabric, pffering the choice between soft, medium, or stiff tactility.  
The company will also preview Litex 4685, a carboxylated formaldehyde-free crosslinking styrene butadiene copolymer for PET-based roofing felt. The product offers a very good heat stand, high mechanical strength, and lowest shrink in machine and cross-direction at elevated temperatures. It also allows the addition of starch as a co-binder.  
Finally, the newly launched Litex QuickShield 1545 provides glass fiber coaters with substantial gains in line speed during coating – while extremely minimizing its emission footprint thanks to a formaldehyde-free and very low ammonia formulation. As an important component of modern facades and wall insulations, the glass fiber fabric plays a leading role in the energy-efficient refurbishment of buildings when mineral wool or foam material insulation is used to optimize their energy demand.
