TIG780-38D — Product overview
TIG™780-38D is an environmentally safe thixotropic thermal silicone grease that combines good stir-ability under shear with strong stay-in-place behavior at rest. When external force is applied the consistency of the grease decreases, providing good stirring ability; once the force is removed the grease becomes static, the consistency increases, and no flow or stringing occurs. The thixotropic rheology improves scratch and coating performance during application, eliminates hanging or sagging on vertical surfaces, supports finer dispensing operations, and delivers good storage stability together with reliable thermal conductivity. The D variant is supplied in a dispenser-friendly form for production-line use.
