WIKO Ultimate Elongation 300ml - UEGUF / UESUF / UEWUF.K300

WIKO Ultimate Elongation Polyurethane Adhesive & Sealant (300ml)

The WIKO Ultimate Elongation is a premium, heavy-duty polyurethane (PU) mastic engineered for extreme elastic bonding and structural sealing. While standard silicone sealants often tear under heavy mechanical movement, and traditional construction adhesives crack when exposed to thermal expansion, this advanced PU formula boasts an astonishing elasticity of up to 800%. Designed to stretch, compress, and absorb massive structural vibrations without ever breaking its adhesive bond, it creates a permanent, waterproof seal. Completely silicone-free, fully paintable, and significantly more user-friendly than older, harsher polyurethane formulas, it is the vastly superior choice for demanding construction, automotive, and marine sealing applications.

Key Features

• The WIKO Advantage — Extreme 800% Elasticity: Unlike rigid adhesives that snap under pressure or cheap sealants that tear, this advanced formula can stretch up to 8 times its original size. It flawlessly absorbs severe joint movement, heavy vibrations, and the natural expansion and contraction of building materials.

• 100% Paintable & Silicone-Free: Standard silicones repel paint, leaving ugly, unpaintable lines on your projects. This polyurethane mastic is completely silicone-free, allowing it to be easily painted over or varnished once cured for a seamless, invisible finish.

• User-Friendly PU Technology: Traditional polyurethane sealants can be highly toxic, difficult to tool, and emit harsh odors. The WIKO formula is chemically optimized to be significantly safer, smoother to gun out, and much easier for the operator to shape and finish.

• Ultimate Weather & Moisture Resistance: Forms a permanent, highly durable shield against the elements. It easily withstands heavy rain, harsh UV rays, freezing temperatures, and constant humidity without shrinking, cracking, or losing its adhesive grip.
