Thin film encapsulants, ultra-low shrinkage, and niche applications are our specialty.

Quality Ensured

Reliable encapsulants backed by global resources and trusted solar market leadership.

Proven in space

H.B. FULLER PHOTOCAP® encapsulants are proven in space.

Our encapsulants are field-proven product backed by over 45 years of experience. H.B. Fuller PHOTOCAP® encapsulants consistently exceed the industry standard with evidence from our performance and long-term reliability studies. Acquired by H.B. Fuller and partnered with TONSAN® adhesives, our PHOTOCAP® encapsulant business is backed by global resources and trusted market leadership.

Manufactured outside of Cleveland, OH, we can offer customers high-quality encapsulants with lower transportation costs and supply risks as well as the value of knowing where the product is and when it will arrive.

Global R&D and technical support teams that are regionally located will work directly with our customers to improve their lamination processes and, in turn, improve the quality of their modules and increase yield. H.B. Fuller’s R&D facilities, equipment, and IEC testing capabilities for our encapsulants enable us to develop, test, and scale up in-house. We perform aging testing and IEC testing on all of our products to ensure longevity and reliability.

H.B. Fuller is a custom encapsulant provider, working with our customers to create products to custom specifications and niche applications. We are capable of producing thinner encapsulants down to a thickness of 0.1mm while maintaining best-in-class performance, including ultra-low shrinkage.

PHOTOCAP® encapsulants are proven on Earth and in space. H.B. Fuller PHOTOCAP® encapsulants are a critical component of PV modules powering satellites. Thinner encapsulants allow for the lightweight, flexible modules needed in these applications. H.B. Fuller is actively engaged in pushing the industry forward with novel satellite PV modules.

As a total solution provider, H.B. Fuller also has a full range of adhesive and sealing solutions for PV applications, from manufacturing to installation. Click here to see all that H.B. Fuller has to offer through our H.B. Fuller, TONSAN®, and PHOTOCAP® brands. For more information on how we can partner with you, contact us.

Technologies

Ethylene Vinyl Acetate (EVA) has been the go-to material used in solar encapsulantsethylene vinyl acetate since our team launched the first EVA-based encapsulant over four decades ago. H.B. Fuller PHOTOCAP® EVA is the only encapsulant technology with a proven track record of maintaining durability, adhesion, stability, and transparency after more than 25 years of field exposure.

Polyolefin Elastomer (POE) materials have emerged to meet the challenges of new modulepolyolefin elastomerdesigns that are sensitive to moisture. Thin film devices, hetero junction cells, and glass/glass modules all benefit from superior moisture resistance while large panels and high-power outputs gain from improved volume resistivity. H.B. Fuller’s superior PHOTOCAP® POE product line embodies both of these properties.
