俄罗斯采购需求：聚酯树脂、UV固化低聚物、聚氨酯树脂、UV固化树脂、EB固化树脂、聚酯丙烯酸酯

I'm looking for two specific types of oligomers for my project. First, I need a fluorinated epoxy acrylate with a high refractive index of at least 1.8. The second component should be a methacrylate with a refractive index ranging from 1.4 to 1.45. I've found some products online, but I can't reach the manufacturers or my information seems to be incomplete. The key requirement is that the high-refractive index oligomer must be acrylic while the low-refractive index one should be methacrylic. They need to be miscible with each other. The acrylic oligomer doesn't necessarily have to be fluorinated, and it's okay if it contains heavy metals, as long as it remains compatible with the methacrylate. If you don't have these exact products, please let me know the maximum refractive index you can offer.
