About the product
Seal and bond without it being noticeable
Pattex SP 101 Transparent is the fully transparent version of Henkel's Flextec technology. It maintains the multi-material sealing and bonding power of the range, but visually disappears into the joint. It is the choice when the finish matters as much as the watertightness: shower screens, glass joints, furniture finishes, steps, and visible trims.
THE MOST ELASTIC IN THE FAMILY: 90% elastic recovery and low modulus (Shore A 35), with movement of up to ± 25%. Absorbs expansion without tearing and without marking the joint.
Why choose SP 101 Transparent
- ✓ Maximum transparency: invisible sealing and bonding, with no marked line or milky tone.
- ✓ Wide temperature range: from -40 °C to +80 °C, more cold-tolerant than the rest of the SP 101 range.
- ✓ Fungicidal efficacy: prevents mold formation, suitable for bathrooms and damp areas.
- ✓ Adhesion without primer on metals, glass, construction materials, and technical plastics (PVC, methacrylate, ABS, polycarbonate).
- ✓ Resists UV rays and can be applied even on damp surfaces and at low temperatures.
- ✓ Free of classified hazardous substances.
