Which additives can improve the transparency of screen printing silicone?
Vulcanization activator
Nano zinc oxide: In the rubber industry, especially in the production of transparent rubber products, nano zinc oxide is an excellent vulcanization activator. Since nano zinc oxide can be combined with rubber molecules at the molecular level, it can improve the performance of the rubber compound, improve the characteristics of the finished product, and help improve the transparency of screen printing silicone.
Polyol and amino alcohol activators: In non-carbon black reinforced rubber compounds, polyols and amino alcohol activators can be added to weaken the adsorption of non-carbon black reinforcing agents such as white carbon black and clay on the accelerator, so as to give full play to the effectiveness of the accelerator and improve the transparency of the vulcanized rubber.
Surfactant
Leveling agent: Usually a surfactant, it can reduce the surface tension of the ink. Its main function is to improve the fluidity and smoothness of the ink, reduce surface defects such as orange peel effect and bubbles that occur during printing, and make the surface of screen printing silicone smoother and smoother, thereby improving transparency.
Wetting agent: It is also a surfactant that can enhance the affinity between ink and substrate, improve the wettability of ink on the surface of substrate, ensure that ink can fully penetrate into the surface of substrate, reduce defects caused by loose bonding between ink and substrate, and thus improve transparency.
Other additives
Nano silver ion antibacterial agent: such as Micro-KF108, which uses glass particles as carriers, so it can maintain the transparency of the material by controlling its refractive index. It can be used for transparent silicone, etc., while improving antibacterial properties without affecting transparency.
Silane coupling agent: It can improve the compatibility and bonding between silicone and other additives or substrates, reduce phase separation and precipitation caused by compatibility problems, and thus improve transparency. For example, in screen printing silicone with fillers, silane coupling agents can make the fillers better dispersed in the silicone matrix to avoid the influence of fillers on transparency.
