Description
Sikaflex® HY 100 is a low-modulus, non-sag, fast-curing hybrid sealant engineered for high-movement building joints in both vertical and horizontal applications. Leveraging advanced Sika hybrid technology, it offers superior adhesion to a wide variety of substrates—including concrete, masonry, metal, wood, EIFS, aluminum, vinyl, and stone—without the need for primers in many cases.
Ideal for use in storefronts, expansion joints, precast panels, window and door perimeters, roofing, parapets, and sanitary areas, Sikaflex® HY 100 provides a weather-tight, flexible seal that resists chalking, cracking, and fading. It meets ASTM C920, Class 50 standards and is suitable for green concrete applications (within 72 hours of pour).
The Sikaflex® HY 100 Tint Base allows for custom tinting using Sikaflex®-900 pigment, with over 40 standard colors available. The sealant is paintable, low-emitting, and compliant with all VOC regulations, making it ideal for environmentally sensitive applications like schools, healthcare, and residential buildings.
