EP0409.07.30 – Glycidyl POSS Nanosilica Dispersion

Description

EP0409.07.30 Nanosilica Dispersion is two reinforcing agents in one. EP0409 is a hybrid, 1.5nm molecule with an inorganic silsesquioxane at the core, and organic glycidyl groups attached at the corners of the cage, which acts as a multifunctional crosslinker. 30 weight percent of 20nm nanosilica is completely dispersed into the EP0409, creating a clear, colorless liquid which is easily blended into other sytems. EP0409 serves as a high temperature reactive diluent in both aromatic and aliphatic epoxy resin affording 40%-70% viscosity reductions. EP0409 can be formulated with aliphatic amines to provide, low viscosity, room temperature cure and high HDT composite resins and adhesives. The “POSS®-HDT-Effect” is recognized by increased rubbery plateau modulus. POSS® molecules also have robust resistance to environmental degradation such as, moisture, oxidation, corrosion, and various types of radiation. The 30% silica improves the reinforcement even more. EP0409.07.30 Nanosilica Dispersion is available in 100g and 1 kg quantities.

描述

纳米二氧化硅分散体是两种补强剂合二为一。EP0409是一种1.5nm的杂化分子，其核心是无机的硅氧烷，笼状结构的四角是有机的甘油三酯，作为多功能交联剂。30%重量的20nm纳米二氧化硅完全分散到EP0409中，形成一种透明、无色的液体，很容易混入其他系统。EP0409作为高温反应稀释剂，适用于芳香族和脂肪族环氧树脂，粘度降低40%-70%。EP0409可与脂肪胺配制，提供低粘度，室温固化和高HDT复合树脂和粘合剂。“POSS®- hdt效应”通过增加橡胶平台模量得到认可。POSS®分子还具有强大的抗环境退化能力，如潮湿，氧化，腐蚀和各种类型的辐射。30%的二氧化硅进一步改善了增强效果。纳米二氧化硅分散体有100克和1公斤的数量。
