water resistance and has the industry- recognized validations to prove it. Available in one and two-component pourable and non-sag formulas and a broad spectrum of colors, Bostik has the product to meet the needs of the most demanding commercial applications.

What is “Strength in Specification”? In short, it is meeting a higher standard of performance and having the industry-recognized validations and accolades to back it up: ASTM C-920, D3498, AFG-01, HUD UM60, AAMA 800, 713, SWRI validated products and Miami-Dade approved.


Adhesion to Arkema's Kynar® Resin-Based Coatings

Arkema introduced Kynar 500® PVDF resin in 1965. For over 50 years, Kynar 500® resin- based coatings have been the industry standard, providing protection and preservation to aluminum, galvanized steel and aluminized steel. With extreme weatherability, excellent dirt shedding and mildew resistance, they make metal functional and eye-pleasing, adding a unique finish that resists chalking, pitting, chipping or premature aging.

However, these coatings are slick, which traditionally has made adhering to their surfaces difficult.

Bostik has solved this problem by developing a full line of high-performance sealants and adhesives that have unprimed adhesion to Kynar resin-based coatings. These smart solutions provide a watertight bond to a variety of applications and improve systems as a whole.

Bostik, Inc. is the only recommended supplier of sealants and adhesives for Kynar 500® resin-based painted surfaces.


Best-in-Class Warranty

Bostik’s manufactures a line of innovative sealants that are backed by a gold seal, best-in-class warranty. The warranty includes a jobsite mock up, which entails an adhesion test to determine the correct technology and product for the application. By conducting this test, Bostik ensures that it understands the true performance of its products. It also reassures contractors that the right product will be used for a project the first time.

Bostik’s best-in-class warranty also can provide labor and material coverage, not just material replacement. This important warranty aspect ensures customers that Bostik will fix a problem should one occur. Additionally, it gives transferable protection to building owners and confidence to contractors.
