ST-HC1710 Thermal Conductive Structural Adhesive
Product Introduction
- Product Overview: Thermal conductive adhesive is primarily used to facilitate heat transfer between materials, transferring heat from high-temperature zones to low-temperature zones to achieve effective heat dissipation and extend component lifespan. With the widespread adoption of new energy power batteries and energy storage batteries, coupled with advancements in traditional electronic component processing capabilities and the trend toward smaller, more compact electronic modules, the demand for efficient heat dissipation has significantly increased. Thermal conductive materials provide long-term, reliable protection for sensitive circuits and components in harsh environments.
The adhesives used in power batteries and energy storage batteries mainly include structural adhesives (for thermal conductivity and insulation), potting and sealing adhesives (for sealing and thermal conductivity), and functional adhesives (for thermal conductivity and electrical conductivity). Thermal conductive structural adhesives serve as the "muscle tissue" that ensures the long-term power performance of power batteries.
The iterative advancement of CTP technology and the increasing integration of new energy vehicles have simultaneously elevated the performance requirements and key technical specifications for thermal conductive structural adhesives. Santam Technology's composite thermal conductive structural adhesive is a series of solvent-free, eco-friendly, high-strength, two-component thermal conductive adhesives. Compared to polyurethane thermal conductive adhesives, it exhibits superior tensile strength and overlap shear strength, low thermal resistance, high thermal conductivity efficiency, high flame retardancy rating, excellent aging resistance, and superior insulation properties.
This product has the following features:
1) It can replace bolt components, simplifying the structure, reducing weight, and increasing the energy density of the battery pack per unit volume.
2) High fracture elongation and elastic modulus, high bonding strength, can withstand 12m free fall and 120 km/h vehicle speed impact;
3) Flame-retardant rating UL 94-VO, ignites and extinguishes instantly upon contact with fire;
4) Demonstrates excellent performance through thermal cycling and humidity-heat aging tests;
5) Excellent insulation performance with adjustable thermal conductivity parameters.

Construction process recommendations:
1. Cleaning: Remove dust, water, and oil stains from the product surface, and maintain dryness.
2. Mixing: Before proportioning, first stir Agent A to incorporate the pigment (filler) that has settled at the bottom into the adhesive solution.
3. Mixing ratio: Weigh the ingredients according to the A/B ratio of the purchased product and pour them in sequentially (*Note: Use weight ratio, not volume ratio).
4. Mixing: Thoroughly mix the prepared A/B adhesive to prevent incomplete curing.
5. Defoaming: After mixing and stirring the adhesive, let it stand for 5-10 minutes to allow natural elimination of bubbles. If conditions permit, vacuum defoaming may be performed.
6. Application of adhesive: Pour the degassed adhesive into the product requiring adhesion, and use it within the recommended time frame.
