About Sealex

Sealex International, Inc. prides itself on its achievements of developing unique patented silicone extrusion technology. Sealex consists of a small, yet productive and flexible collection of talents, whose mission is to develop and manufacture innovative products to serve the sealing needs of various industries.

Sealex Building Sealex was founded as Sealex, Inc. by Peter Hagen in 1992 in Midland, Michigan. Peter's two sons, Matthias and Robert, have also played key roles in the development of the company. Two years of research and development work for the product and process yielded a unique pre-cured silicone sealant product along with all the equipment necessary to produce it. In 1994 Sealex relocated to Harbor Springs, Michigan and in 1996 Peter contracted the construction of a new 10,000 ft2 manufacturing and development facility which now houses all of Sealex’s operations. In 2007 a 3,000 ft2 addition to the facility was built to meet the increased warehousing and production needs of the growing company.

Early on in the development of the company, Sealex’s pre-cured sealant products were commercialized in conjunction with several major marketing partners in the weatherproofing segment of the construction industry. These partnerships are still in place and strong today and the products have a bright future in this area of the industry. Over the past several years, the ImmerSeal® and ImmerBond® pre-cured silicone sealant and silicone adhesive product lines were developed. These products have been introduced and integrated into a variety of markets within the construction industry including weatherproofing, metal buildings, IG/Window/Door, transportation, and many others.

In addition to supporting and serving its customers, Sealex’s goal has always been to continuously improve its products and processing capabilities while maintaining uncompromised quality standards. Sealex’s flexibility with respect to processing and product design is enhanced by an extensive laboratory featuring state of the art testing equipment and computerized color matching capability. Sealex’s capabilities include in house CAD - CAM custom die fabrication coupled with extensive experience in custom die design and support. The facility offers ample production capacity and room for expansion.

Sealex's commitment to constantly improve upon its patented silicone extrusion technology in conjunction with its focus on customer satisfaction and service has proven to be a successful combination
