Thermal bonding. Dow DOWSIL 1-4173 TC Thermally Conductive Adhesive Gray is a one-component, solvent-free adhesive used for bonding electronic components, housings, lids, base plates, and dispensing equipment. It is heat-curing, self-leveling, and flowable, with good thermal conductivity and high tensile strength. This syringe is a Dow product repackaged by KitPackers.
Performance profile. Dow characterizes 1-4173 as a one-part, gray, flowable thermally conductive adhesive with high tensile strength. Its self-leveling nature helps it form an even layer, while its thermal conductivity conducts heat from components to heat sinks, housings, or base plates.
Durability. Distributor data notes 1-4173 provides flowability, chemical stability, and resistance to shock, ozone, stress, and environmental contaminants, supporting durable bonds in demanding electronics. As a solvent-free silicone with a ceramic filler, it forms a robust thermal and mechanical bond on cure.
Handling notes. As a heat-cure adhesive, the material is cured by applying heat, giving controlled processing. The 30 mL syringe is well-suited for precise, small-scale dispensing and rework. Review the product and Safety Data Sheets and confirm the cure schedule before production use.

FAQs
What is DOWSIL 1-4173 TC used for?
It is a one-part, solvent-free thermally conductive silicone adhesive for bonding electronic components, housings, lids, base plates, and heat sinks. It combines high tensile strength with good thermal conductivity, so it holds parts firmly while dissipating heat from components to heat-dissipating surfaces.
What does 'self-leveling' mean for this adhesive?
Self-leveling means the flowable adhesive settles into an even layer after dispensing, helping form a uniform bond line and good contact between surfaces. That even layer supports consistent thermal transfer and strong adhesion, which is valuable when bonding flat components like base plates and lids.
How is 1-4173 cured?
It is a heat-cure adhesive, so the dispensed material is cured by applying heat rather than at room temperature. Heat cure gives controlled, on-demand processing suited to production. Consult the technical data sheet for the recommended cure temperature and time for your components and equipment.
How durable is the cured adhesive?
Distributor data notes it offers chemical stability and resistance to shock, ozone, stress, and environmental contaminants, along with high tensile strength. As a solvent-free, ceramic-filled silicone, it forms a robust thermal and mechanical bond that holds up in demanding electronic service environments.
What is the 30 mL syringe good for?
The 30 mL syringe format suits precise, small-scale dispensing and rework, where a large cartridge or pail would be excessive. It delivers the same genuine Dow 1-4173 adhesive, repackaged by KitPackers, in a convenient size for benchwork, prototyping, and targeted component bonding.
