H.B. Fuller is committed to sustainable business practices. That’s why one of our major focuses is clean, solar energy (PV) and wind energy, because we understand that the world’s finite resources require us to minimize our impact on the environment while creating value for our customers.

Clean, Solar Energy (PV)

We work to create high performance, effective adhesives and sealants for the solar market, one of the fastest-growing energy technologies, that simplify panel assembly and increase reliability and longevity. We customize our packages, enabling faster installations, reduced labor hours, and lower costs.

Frame Sealing and Junction Box Attaching

This key material connects the frame and the component, with permanent anti-environmental aging properties. These sealants furthermore maintain long-term reliable sealing and bonding and prevent PV modules from being affected by the external environment.

  • 1527/1581 Silicone Sealant for PV Modules

Junction Box Potting

This solution improves the insulation grade of the J-box and the head dissipation while avoiding the risk of diode failure as a result of overheating, and ultimately reduces the overall cost.

  • 1521 Potting Compound for Junction Box

Rail Bonding

Elastic bonding is needed between the frameless PV modules and back rails to compensate for the deformation caused by temperature variation in outdoor environments, and meanwhile satisfying the mechanical load requirements. The rail bonding adhesive has excellent elastic deformation ability and high bonding strength with both glass and metal.

  • 1522 Fast Cure Structure Adhesive
  • 1523 Bonding Sealant for Back Rail

Edge Sealing

Edge sealing can effectively prevent outside moisture or other substances from having negative influence on the frameless PV modules and strengthen insulation protection.

  • PIB6510/PIB6520 High Efficiency Edge Sealant

Temporary Bonding During Ingot Mounting

These materials were developed for temporarily bonding of mono crystal and poly crystal PV silicone ingots. Both epoxy and anaerobic type materials are offered. These materials can improve production efficiency and enhance production yield.

  • 3201/3220/TS827/TS837 Ingot-Glass Bonding Adhesive
  • 3211 /TS826 Glass-Substrate Bonding Adhesive

PV System Installation Sealing and Bonding

Materials used for reliable sealing of the main roof structure to prevent water permeation during residential and utility PV roof installation.

  • MS1937 Sealant for PV System Installation
  • 1581 Silicone Sealant

Dispensing Tools and Machines

We focus on integrating sealing and bonding solutions and, together with excellent adhesive, we research and develop high-performance dispensing equipment to satisfy the requirement for stable and reliable production, including:

  • Automatic Dispensing Machines for Frame
  • Automatic Dispensing Machines for Junction Box
  • Automatic Junction Box Potting Machine
  • Automatic Edge Sealing Machine

For more than a decade, H.B. Fuller TONSAN’s proven adhesive solutions have successfully helped many leading wind energy manufacturers grow their businesses around the world. Whatever your wind energy needs are, from sealing and bonding to maintenance and cleaning, we offer high-quality solutions that deliver reliable and excellent performance.

Wind Energy

We participated in the preparation of multiple certification technology standards, including:

  • CGC/GF012:2011 Wind Turbine Blade Structure Adhesive Specifications
  • CGC/GF015:2011 Wind Turbine Fastener Specifications

Our sealants, adhesives, lubricants, and cleaners have been widely applied to 750KW, 1.5MW, 2MW, 3MW, 3.6MW and larger wind turbines. Relying on over a decade of customer service experience and an in-depth study of the application technology in the wind energy industry, our participation in the preparation of relevant large-scale wind turbine parts certification specifications, and facilitation of the development of the standards for the wind power industry has allowed for the improvement of the quality, which has resulted in greater reliability and service life of wind turbines overall.

We carry out comprehensive reliability tests, such as high/low temperature, moist-heat, QUV ageing, salt-mist, and fatigue torsion, as well as others, in order to make wind turbine operations safer and more reliable and durable.
