Chem Link’s E-Curb Solar Sealant

Since its founding in 1990, Chem Link, Inc., has focused on meeting the pressing needs of contractors, consumers and industries with its high-performance adhesives, sealants, coatings and related products for applications throughout the building envelope. An idea company, dedicated to innovation and problem-solving, Chem Link joined the SOPREMA family in 2016, committed to continuing to provide its customers with quality products and customer service.

Since day one, Chem Link has been an environmentally conscious company. All of its internal processes are environmentally compliant, from product formulation through production and packaging. All products are solvent free and have a low VOC content, meaning they pose no threat to the installer and are environmentally friendly.


Chem Link is an industry leader because of its simple seal system for difficult roof penetrations – the E-Curb System.

Penetrations are the most common source of roof leaks. The best low-slope roof is compromised the moment it’s punctured. Punctures can occur from mechanical fasteners, pipes, electrical conduits, solar arrays, lighting support, wiring, HVAC, etc. Every penetration is an invitation for water to pass through the membrane and into the building’s interior.

To protect the original investment of the roof, avoid callbacks and prevent damage caused by water, building owners and contractors should choose the most effective, proven, long-term penetration seal available: Chem Link’s E-Curb System. Curbs can turn the weakest part of a building’s roof into the strongest.

  • Easy to install – normally fewer than 15 minutes per penetration
  • Fits any size or shape penetration allowing for unlimited configurations
  • Can be bonded to a wide range of surfaces
  • Sealants and adhesives are 100% solids and do not shrink
  • E-Curb installations are impervious to ice, corrosion, UV light and ponding water.
  • Adhesives and sealants are solvent-free and contain virtually no VOCS, minimizing health risks to contractors and building occupants.


Chem Link’s curb systems are ideal flashing systems for solar racking standoffs because they are efficient and easy to install, regardless of the installer’s skill set. Curb systems are superior to other penetration seal systems that are notorious for corroding, are labor intensive and do not offer configuration flexibility. This system will save installers time and labor, leading to cost savings.


E-Curbs are highly versatile for sealing penetrations around HVAC, electrical and any type of structural supports. E-Curb penetration seals replace old-style metal pitch pans with versatile, precast components and 1-Part polyether pourable sealants. Chem Link’s E-Curb System can usually be installed in under 15 minutes and never requires flashing or mechanical attachment.
