Breakthrough adhesive adheres to PVDF coated metals known to be impossible to stick to.
Sika Corporation – Roofing is pleased to announce the addition of SikaFast 3341 adhesive to our PVC and Liquid-Applied (LAM) product line. This breakthrough adhesive is specially formulated to bond to substrates known as "impossible" to stick to, such as PVDF resin-based metal coatings, better known as Kynar®, Hylar®, etc.
The PVDF resin technology that makes the coating perform so well with color retention, gloss sheen longevity, and UV resistance makes it very difficult for anything to stick to the coating. That is, until now, thanks to SikaFast 3341!
SikaFast 3341 is a 2-component, self-mixing adhesive that comes in a dual-cartridge container, and the mixing nozzle comes with a special trowel attachment for a clean application.
SikaFast 3341 adhesive allows the use of PVDF resin coated metal, such as Kynar, to be fabricated and installed at the roof edge or top of parapet walls to then bond to Sarnafil S 327 membrane cover strip (for PVC membrane system) or Sikalastic RoofPro resins (for liquid applied membrane systems), forming a rigid bond once cured.
SikaFast 3341 adhesive is available to order. SikaFast 3341 is eligible for up to a 20-year coverage under Sika's Systems Warranties for both PVC and LAM, provided it is purchased by the Sika Authorized Applicator from Sika Corporation – Roofing.
