The thermal curing cycle used in simulation runs was the one optimized for the DGEBA/ MTHPA-BTEAC formulation (with 4 wt% BTEAC).
After the end of the pot life of the epoxy matrix a three-step curing cycle was applied.
Prevalence of malpractice, such as adding another flask to an on-going curing cycle or revival of water bath with cold water or cooling of a flask under tap water was negligible and was probably due to a lack of experience or training in the concerned field.
ET refers to rubber details utilized in the aerospace industry to fabricate composite parts of various sizes and shapes in order to intensify or redistribute the pressure during a curing cycle, to avoid bridging, wrinkling in comers or bag rupture in tight radii (ref.
In combination, Huntsman says the system's good thixotropic and low exothermic properties lead to improved process efficiencies, characterised by easy handling and mixing, a long pot life of 240 minutes at 23[degrees]C, fast strength build-up and reduced curing cycle capabilities.
As the product is non-drip and non-saggging, the drying and curing cycle can start immediately.
Manufacturers using the material still find it difficult to get higher production rates without bottlenecks in the curing cycle.
The unit produces an audible signal at the end of each selectable curing cycle. Curing cycles are selectable at 10, 20, and 40 sec and a manual selection provides continuous operation.

Popping involves the formation of defects by the violent evolution of trapped solvent or other volatiles after the coating has begun to gel during its curing cycle. The result may be miniature volcanoes, pinholes, craters, dimples, bubbles, or a few of each.
