3M™ Dyneon™ Fluoroplastic THV 340Z is designed for coating heat sensitive substrates such as polyester fabrics. It has a lower fusion temperature and high melt flow index to improve penetration and reflow. The product is also suitable for coating PTFE fabrics, made out of pure or mixed PTFE yarns. There is a good balance of flexibility, weatherability, chemical resistance, and anti-soiling properties in a waterbased formulation.
THV 340Z performs with the following distinctive features:
melting point compatible with many substrates
high flexibility without the need for plasticizers
resistance to soiling and staining
good chemical resistance
high transparency
UV resistance
We recommend to dry the coating with approximately 90 °C prior to the melting process. To achieve a uniform film during the melting process, use temperatures approximately 50 °C above the melting point. Fillers such as glass bubbles Ti02 and colored pigments may be added.
