Title: Annette Lavalette: Innovator in Adhesive Compositions
Introduction
Annette Lavalette is a distinguished inventor based in Richmond, GB. She has made significant contributions to the field of adhesive compositions, holding a total of 2 patents. Her innovative work focuses on developing materials that enhance the performance and application of adhesives.
Latest Patents
Annette's latest patents include two notable inventions. The first is an adhesive composition that features linear saturated copolyesters of terephthalic acid, isophthalic acid, butanediol, and one or more aliphatic diols with at least 13 carbon atoms. This composition is designed for creating wash-resistant bonds, particularly for temperature-sensitive materials. The melting points of these adhesive compositions range from 50°C to 170°C, and their relative viscosities, measured as 1% solutions in meta-cresol at 20°C, fall between 1.40 and 1.80.
The second patent is an adhesive copolyamide composition based on phenylene-containing diamine. This composition boasts a dry powder DSC melting point of at least 100°C, a glass transition temperature above 60°C, and a dry powder softening point of at least 100°C. It is noteworthy that after storage in water, the composition retains more than 20% by weight of water content, with a wet softening point of less than 100°C. These compositions exhibit softening points and heat resistances exceeding 100°C, allowing for processing and setting at significantly lower temperatures without the need for low molecular weight additives or solvents. They are comparable in heat resistance, softening points, and bond strength to conventional high-performance hot melt adhesives.
