BERGQUIST LIQUI BOND TLB SA1800

Bergquist LIQUI BOND TLB SA1800 Thermally Conductive One-Part Liquid Silicone Adhesive

What Is Bergquist LIQUI BOND TLB SA1800?

Bergquist LIQUI BOND TLB SA1800 — also known as Bergquist LIQUI-BOND SA 1800, one-part thermal silicone adhesive, thermally conductive bonding adhesive, or liquid silicone thermal adhesive — is a high-performance, one-component thermally conductive liquid silicone adhesive by Bergquist (Henkel) that cures to a solid, high-strength bonding elastomer upon application of heat. Unlike two-part adhesives requiring on-site mixing, or conventional thermal interface pads requiring mechanical fasteners for retention, LIQUI BOND TLB SA1800 simplifies electronic assembly by combining reliable structural bonding, effective thermal management, and process-friendly application in a single one-part material — eliminating the weight, assembly time, and complexity associated with mechanical fasteners.

The low viscosity of Bergquist LIQUI BOND TLB SA1800 makes it uniquely suited for screening and stencilling processes, enabling precise, uniform bond line formation at high production volumes — as well as automated pattern dispensing for modern electronics manufacturing lines. Once heat-cured (20 minutes at 125°C or 10 minutes at 150°C), it forms a structural bond with a shear strength of 1.4 MPa (200 psi) and a Shore A hardness of 80, while retaining mild elastic properties that relieve coefficient of thermal expansion (CTE) stresses during repeated thermal cycling — maintaining bond integrity in the most severe aerospace, automotive, and industrial environments. With a thermal conductivity of 1.8 W/mK, a dielectric strength of 10,000 V/mm, and an operating temperature range of -60°C to +200°C, it is the thermal bonding adhesive GCC electronics manufacturers trust for PCB assembly-to-housing bonding and discrete component-to-heat-spreader attachment. Maisam Trading LLC is the authorised Bergquist supplier in Dubai, with refrigerated stock maintained at the required 10°C storage temperature for prompt delivery across the UAE, Saudi Arabia, Qatar, Oman, Kuwait, and Bahrain.

Description

Bergquist LIQUI BOND TLB SA1800 is the fastener-replacement thermal bonding adhesive of choice for high-reliability electronics manufacturing, MRO, and OEM applications where thermal management and structural bonding must be achieved simultaneously and efficiently. Available from Maisam Trading LLC Dubai, this one-part thermally conductive liquid silicone adhesive is supplied in tube and mid-sized container forms and is suitable for both screen/stencil application in high-volume PCB production environments and for automated pattern dispensing in modern assembly lines.

The material achieves a very thin bond line due to its low viscosity — producing excellent thermal performance at the interface and maximising heat transfer between the bonded component and the adjacent heat spreader or housing. The cured elastomer’s mild elastic properties absorb dimensional mismatches caused by differences in coefficient of thermal expansion between bonded substrates, preventing delamination or cracking during repeated thermal cycling across the full -60°C to +200°C service temperature range. An optional glass bead spacer variant is available to provide a consistent bond line standoff and ensure dielectric integrity in applications with tight dimensional requirements.

The product contains no cure by-products, making it compatible with sensitive electronic components and sealed assemblies. It requires refrigerated storage at 10°C with a shelf life of 6 months — Maisam Trading LLC maintains appropriate refrigerated storage to ensure product integrity on all deliveries to customers across Dubai, Saudi Arabia, Qatar, Oman, Kuwait, and Bahrain. As a trusted thermal interface adhesive supplier in the UAE and GCC, Maisam Trading LLC provides full technical support, TDS, and SDS on request.

Technical Specifications

FAQs

Q1: What is Bergquist LIQUI BOND TLB SA1800 used for? It is a one-part thermally conductive liquid silicone adhesive used for structural thermal bonding of PCB assemblies to housings and discrete components to heat spreaders. It eliminates the need for mechanical fasteners while providing 1.8 W/mK thermal conductivity and maintaining bond integrity in severe environments.

Q2: Is LIQUI BOND TLB SA1800 suitable for screening and stencilling? Yes. Its low viscosity of 125,000 mPa·s makes it compatible with screen and stencil application processes as well as high-volume automated pattern dispensing — making it ideal for both low-volume MRO and high-volume OEM production environments.

Q3: What is the cure schedule for Bergquist LIQUI BOND TLB SA1800? The standard cure is 20 minutes at 125°C or 10 minutes at 150°C — measured after the cure temperature is achieved at the interface. Ramp time is application dependent. These are guideline recommendations and may vary based on equipment and application conditions.

Q4: Why does LIQUI BOND TLB SA1800 require refrigerated storage? The one-part heat-cure chemistry requires storage at 10°C to maintain stability and prevent premature crosslinking. Maisam Trading LLC maintains appropriate refrigerated storage to ensure product integrity on all deliveries across the GCC.

Q5: What is the glass bead option? LIQUI BOND TLB SA1800 is available with optional glass beads that provide a consistent bond line standoff and ensure dielectric integrity at the interface — particularly useful in applications with tight dimensional requirements or where controlled bond line thickness is critical.

Q6: Does LIQUI BOND TLB SA1800 relieve CTE stresses during thermal cycling? Yes. The cured elastomer retains mild elastic properties that absorb dimensional mismatches caused by differences in coefficient of thermal expansion between bonded substrates — preventing delamination or cracking during repeated thermal cycling across -60°C to +200°C.

Q7: Is Bergquist LIQUI BOND TLB SA1800 suitable for aerospace and defence applications? Yes. With an operating temperature range of -60°C to +200°C, UL94 V-0 flame retardancy, high shear strength of 1.4 MPa, and no cure by-products, it meets the requirements of aerospace, aviation MRO, and defence electronics thermal bonding applications.
