Reactive Diluent (Reactive Diluent) Definition Reactive diluents mainly refer to low molecular epoxy compounds containing epoxy groups. Reactive diluents can participate in the epoxy resin curing reaction, become part of the epoxy resin curing material crosslinking network structure.   Classification of reactive diluents Reactive diluents are divided into single epoxy-based reactive diluents and multi-epoxy-based reactive diluents.   Characteristics of reactive diluents Epoxy resin reactive diluent to participate in the curing reaction, do not have to worry about volatile emissions in the reaction. And the molecular structure of the active diluent contains epoxy group, in the case of the appropriate amount of use, the performance of the curing material does not have a great impact on the different molecular structure of the active diluent will also provide a certain function for the curing material, such as toughening, low-halogen, to improve the mechanical properties, to increase the temperature resistance and so on.   Active diluent product categories   Commonly used monofunctional active diluent Features: low viscosity, low colour, good dilution effect, widely used. C12-14 alkyl glycidyl ether: dilution effect is good, ordinary common type active diluent, widely used Butyl glycidyl ether: good dilution effect, high reactivity to amine curing agent, but heavy odour Phenyl glycidyl ether: benzene ring, high reactivity to amine curing agents, good temperature resistance   Commonly used bifunctional group active diluent Characteristics: contains double epoxy groups, lower viscosity at the same time, more prominent reactivity, good flexibility. Commonly used products include: 1,4 butanediol diglycidyl ether Polypropylene glycol diglycidyl ether Ethylene glycol diglycidyl ether   Trifunctional group active diluent characteristics: participate in the epoxy resin curing reaction, can form a three-dimensional network structure, because of the presence of special functional groups, help to improve the performance of some of the cured material.   The use of active diluents Monofunctional active diluent viscosity is low, the dilution effect is good, the dosage is 10-15%; the use of multifunctional active diluent viscosity reduction effect to achieve the standard of monofunctional active diluent, the dosage will be increased, generally in 20-25%.   Selection of active diluents   Active diluent can be widely used in coatings, adhesives, electronic and electrical and composite materials and other fields. When we choose the active diluent, we should not only consider the viscosity reduction effect, but also consider the performance needs of the epoxy curing material. On the basis of not affecting the original performance of the cured material, while meeting the toughness and strength requirements, low toxicity and safety, etc., are the conditions we need to consider when choosing.   Nanjing Yolatech provides all kinds of high purity and low chlorine epoxy resins, including Bisphenol A epoxy resin, Bisphenol F epoxy resin, Phenolic epoxy resin, Brominated epoxy resin, DOPO modified phenolic epoxy resin, MDI modified epoxy resin, DCPD epoxy resin, Multifunctional epoxy resin, Crystalline epoxy resin, HBPA epoxy resin and so on.
