Shanghai species competition will launch two innovative chemical curing agent - curing agent, epoxy resin - plastic industry

Side branched polyester tertiary amine curing agent

, is the company's R & D of new epoxy curing agent. Terminal tertiary amine branched polyester curing agent, is in the company's researchers synthesized a hyperbranched polyester based on the end of the introduction of tertiary amine groups modified, but are highly active epoxy curing agent, with Reaction and storage stability, and with the toughness of epoxy resin with improved functions. Terminal tertiary amine branched polyester curing agent has many advantages such as low viscosity, light color, to stimulate the taste of small, matching a small amount of initial gel time is long, and the mild reaction leveling effect, hardening time short, and cured color and brightness is good, strong adhesion, good temperature change performance advantages, apply top coat and high-grade adhesives. Another advantage of marketplace competition Shanghai area cashew phenol, which is from the natural waist in a Nutshell by advanced equipment and technology from refining process, can replace or partially replace the liquid phenolic amine for the preparation of phenol resins, and thermosetting liquid or powder form Phenolic resin , Its use is widespread. R & D of cashew phenol modified amine epoxy curing agents, phenolic and amine curing agent generally the most important difference is the substitution of phenol with cashew phenol by Mannich reaction of phenolic amine curing agent. The middle bit Cardanol molecules containing unsaturated double bonds of 15 carbon straight chain substituents, provides a good toughness, excellent water-repellent, low permeability and self-drying and so on.
