Commercial production of pultrusion release agents

Commercial production of pultrusion release agents

Dr. Rezadoust, head of the Composite group in IPPI, announced the commercialization of pultrusion release agents production. He, as the administrator of the production project, said: "Dr. Sheikh Al-Islam, one of the postdoctoral colleagues of Composite group, has completed the research related to the epoxy resin release agent and this product will enter the commercial phase soon."
“In the pultrusion process, used for the production of composite parts in chemical industry, structures, cooling towers and many other industries, it is necessary to use a special additive called an internal release agent to separate the pultruded profile from the die, perfectly”, Dr. Sheikh Al-Islam said.
She added: “this additive must be miscible with the resin in the liquid stage and it will migrate to the interface of the die and the composite during the curing of the resin. Unfortunately, till now these kinds of releases agents totally imported from other countries which were consuming a lot of time and money. In this regard, the synthesis department of Kavian Composites Company which is located in Polymer Incubator of IPPI has started the synthesis of this group of additives, and in the first step, internal release agent for unsaturated polyester resin was developed and commercialized under Kemliz brand by the IPPI license. In the next step, the study phase of the epoxy internal release agent has been done and this product is ready to enter the commercial phase.”
