Kommerling PIB Hot-Melt Sealant Slug 7kg
Used as the primary seal in insulated‑glass (IG) units, it provides exceptionally low moisture‑vapour and gas transmission rates, thereby guaranteeing sustained thermal performance over the long term.
Primary Insulating‑Glass Sealant: Formulated for use as the principal seal within a dual‑seal system for insulated‑glass (IG) units.
Low Permeation Rates: Forms an exceptionally effective barrier to moisture vapour and to the ingress of insulating gases such as argon, helping to preserve the window’s energy‑efficiency over the long term.
Excellent Adhesion: Delivers strong, durable bonding to glass surfaces and to common spacer materials (including aluminium, galvanised steel and stainless steel).
Hot‑Melt Application: Supplied as a solid 7 kg slug that is melted and applied with a heated butyl extruder.
Solvent‑Free: The formulation contains no solvents, making it an environmentally responsible choice.
High Ageing Resistance: Shows robust resistance to ageing, providing dependable long‑term performance.
High Performance: Guarantees an airtight unit, which is essential for maximising thermal performance and extending service life.
PIB stands for Polyisobutylene: Polyisobutylene is a synthetic rubber noted for its very low moisture‑vapour and gas transmission rates. Because of this, it works well as the main sealant in insulated‑glass (IG) units, acting as a vital barrier that stops moisture from getting in and prevents inert gases such as argon from leaking out of the sealed air cavity.
