Expert in Thermoset and Thermoplastic Composites, Flame Retardancy, Low-Profile Additives, and Shrink Control
Expert ID: 733937 North Carolina, USA
During his tenure with the same company, Expert worked with customers in developing formulations for passing required application certification tests such as ASTM E84, UL 723, UL94 V0 and 5VA, ASTM E648, ASTM E662 and E162 (Docket 90).
Near the end of his career at Huber, Expert implemented a new product development program in engineering thermoplastics specifically targeting nylon. The flame-retardant effect of magnesium hydroxide was being studied in conjunction with novel char forming technology.
Currently Expert is consulting with a manufacturer of Nitrogen-Phosphorus flame retardants. The area of consultation involves working with customers in flame-retarding thermoplastic composite and thermoset composites, as well as intumescent coatings and caulks.
Expert worked in the field of low-profile additives (shrinkage control) based on polyvinyl acetate for Class A SMC and BMC while at Union Carbide and later Dow Chemical (after acquisition). The advancement of Class A SMC technology required Expert to acquire skills in physical testing, profilometry, UV weathering, and SMC and BMC formulating. He wrote and presented papers on his research about the low-profile mechanism that explained why low-profile additives control shrinkage and improve surface quality of thermoset composites but also explained the hazing and mottling phenomena observed in pigmented low profile formulations.
In order to diversify the product line away from PVAc, Expert led research into the synthesis of polyurethane oligomers as low-profile additives.
Expert was promoted to technical director in 1998 of the Low-Profile Additives SBU. His technical responsibilities were expanded after the Dow Chemical acquisition as Technology Leader to include the Derakane Vinyl Ester Product line.
Consulting with JLS Flame Retardant Chemical Company for improvement of N-P product line with regard to: 1.) customer processes and applications; 2.) introduce these products to potential customers; 3.) maintain existing customers with technical support. Consulted with J.M. Huber for 6 months with the responsibility of training his replacement in all aspects of his former position which include interpretation of cone calorimetry data, particle size analysis, rheology as well as thermoset composite formulating.
Expert may consult nationally and internationally, and is also local to the following cities: Fayetteville, North Carolina - Wilmington, North Carolina - Jacksonville, North Carolina
