ST-PE1700 Thermal Conductive Sealant
Product Introduction
- Santam Technology's high-strength elastic potting compound overcomes the drawbacks of conventional epoxy resin brittleness and silicone resin's low strength and poor adhesion. It features exceptional strength and toughness, acid/alkali resistance, salt spray corrosion resistance, and high/low-temperature impact resistance with moisture protection. Having passed the dual 85 test, it offers superior insulation performance, environmental friendliness, and high cost-effectiveness, making it the ideal potting material for electronic components.
Our product portfolio caters to diverse customer needs, with customized solutions tailored to specific requirements. Our extensive expertise enables prompt responses to client demands. All products are UL-certified and ROHS-compliant, with dedicated solutions for every potting application.
This product has the following features:
1. Forms a tough elastomer after curing
2. Moderate strength, water-resistant, mold-resistant, shockproof, with excellent
3. Flame retardancy rating meets UL94 V-0
Application: Electronic component encapsulation, such as integrated circuits; electrical equipment sealing, such as transformers; protective function in automotive electronics, aerospace, and communication equipment.

Construction process recommendations:
1. Cleaning: Remove dust, water, and oil stains from the surface of the product to be filled and sealed, and ensure the surface remains dry.
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. Pouring: Pour the degassed rubber compound into the product requiring adhesive application. Use within the recommended timeframe.
