What is the main function of SE300AB?<\/strong><\/p>\n<p>SE300AB is designed to fill small gaps between heat-generating components and heat sinks or housings, reducing interfacial thermal resistance while providing reliable electrical insulation and post-cure elastomeric shock absorption.<\/p>\n<\/p><\/div>\n<div class=\"sheen-faq-item\">\n        <strong>Q2. What is the difference between SE300AB and the 1K SE thermal gel series?<\/strong><\/p>\n<p>SE300AB is a two-component thermal gel that requires mixing before application and cures to form a soft elastomer. Compared with the 1K SE series, it is more suitable for applications that require controlled curing, stable interface thickness, and post-cure shock absorption.<\/p>\n<\/p><\/div>\n<div class=\"sheen-faq-item\">\n        <strong>Q3.
