Sikaflex PRO-3 Purform Polyurethane Sealant
Sikaflex PRO-3 Purform is a one-part, moisture-curing polyurethane sealant designed for sealing joints in floors and civil engineering structures. It provides an elastic, durable seal that can accommodate significant joint movement while resisting mechanical, chemical and weathering exposure.
For customers looking for a reliable sealant for demanding floor and construction joints, Sikaflex® PRO-3 Purform combines high movement capability with good adhesion to many common construction materials. It can be used for both interior and exterior horizontal and vertical joint sealing applications.
The sealant maintains its elasticity across a wide temperature range and has a tensile strain at break of approximately 800%. Its movement capability is rated at ±25% according to EN ISO 9047 and up to ±50% according to ASTM C719.
Sikaflex PRO-3 Purform is supplied ready for use in 600 ml foil packs, making it suitable for professional joint sealing work where controlled application and durable joint performance are required.

Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
