said that the needs of products should be the main, each product has its own advantages and disadvantages, usually dilution capacity will be the primary factor, but according to different needs can also choose HDT, or acidity or toughness as the most important factor. The expert focused on several important commonly used thinner comparison summarized as follows: H61 as an entry-level active diluent, or has its unique use, the ability to reduce stickiness is the biggest advantage of H61, but there is a high vapor pressure and some toxicity risk, as well as the test results of water resistance and poor acid resistance, but in fact to obtain high purity of BGE is actually very difficult, in the face of many impurities on the market, BGE products, these BGE actually contain a large number of icing Alkane and some solvents are the main factors to destroy epoxy products, the general market product addition volume can not exceed 10%, otherwise there will be greater defects, so the general coating workers will think that BGE seriously affects the paint performance, in fact, H61 recommended addition volume of 10-20%, EPON815 is the addition of 20% of the product, so high purity H61 still has and large application potential, especially for those with very strict viscosity requirements of paint products. Of course, the best choice in environmental protection, safety and performance is the most widely available H8 in coatings and potted, commonly known as AGE.
H8 is a carbon chain C12-C14 AGE, as the world's largest production of active diluent H8 also has a fairly ideal dilution capacity, and the performance is also a fat family CE-10 compared to CE-10 due to its larger bit resistance structure, mechanical performance priority H8 several percentage points, as dilution performance, H8 occupies a considerable advantage , the addition of 15% can reduce the standard epoxy resin to 1000cps, and CE-10 to add 20%, H8 in terms of toughness significantly ahead of other modifiers, which is its own rigid large and small toughness of epoxy products, at the expense of partial rigidity to obtain greater toughness is very useful, in particular, can enhance the wear resistance of the material. H8 has a very low surface pressure due to its colorless tasteless color and the best color value of all active thinners, meaning that the material can achieve better leveling performance. H8 is therefore undoubtedly the best price/performance ratio. And the emergence of H62 broke the myth of the advantages of polycyclioxide in materialization performance, H62 in the performance of almost all double epoxy reactive thinners, and polycyctic oxygen thinner performance is not the same, but in dilution performance H62 also exceeds ce-10 monocycic oxygen this does confirm that the role of epoxy thinner is its reasonable molecular structure and purity, the ideal curing product than theoretically perfect but not ideal for solidification of the product. H62 as a special high-performance thinner is undoubtedly the performance of this product test.
