Weicon Urethane 90 SF Polyurethane Adhesive is a fast-curing, self-levelling, two-component polyurethane-based industrial adhesive and casting compound. Its nearly shrink-free curing after application supports dimensional stability in precision casting and fixing work. With a high static strength approach, it can be used on site both for bonding and for filling\/fixing purposes. The manufacturer is WEICON, and the product is part of WEICON\u2019s Germany-origin portfolio.<\/p>\n
Where is the Urethane 90 SF polyurethane industrial adhesive used?
This industrial adhesive offers a versatile solution with an aim of adhesion to different substrates such as metal, concrete, rubber, wood, and fiberglass. It is especially preferred for precision grouting\/casting jobs, such as casting floor anchors, sensors, fastening elements, and position markers for laser measuring. Its self-levelling behavior helps form a more uniform fill layer in molds or cavities. At the same time, thanks to its high adhesive strength, it can also be evaluated as an industrial adhesive for assemblies requiring structural fixing, provided proper surface preparation is applied.<\/p>\n
Technical structure, strength, and key performance character
The product is polyurethane-based and described as brown; after curing it targets a hard and stable structure at a Shore D 90 hardness level. While offering a profile that supports static mechanical strength, its temperature resistance is stated as -60 \u00b0C to +90 \u00b0C. A high shear strength approach is indicated on substrates such as steel and stainless steel at a thin bond gap (about 1.5 mm), meaning surface roughness and cleanliness directly affect the outcome. The mixed viscosity being in a low-to-medium range (about 3,000 mPa\u00b7s) helps keep flow manageable in casting and self-levelling applications. In this sense, the product is positioned to cover the need for a \u201ccasting compound + industrial adhesive\u201d within a single system.<\/p>\n
Mixing, working time, and curing window
The two components are mixed at a ratio of 100:23 by weight (100:31 by volume), and keeping strictly to the mix ratio is considered critical for consistency of the final physical properties. Since a pot life of about 8 minutes at 20 \u00b0C is stated, only as much material as can be applied within this time should be prepared. Reaching working strength in about 2\u20133 hours provides a practical time window for fixturing and assembly flow. Because a curing time of about 24 hours is given for final strength, full loading should be planned with this period in mind. Keeping relative humidity below 70% and avoiding excessively high ambient temperatures during application helps make curing behavior more predictable.<\/p>\n
Surface preparation and application steps
For a successful result, surfaces must be free of oil, dirt, rust, oxides, and loose layers; otherwise, adhesion and full curing can be negatively affected. On smooth or heavily soiled surfaces, mechanical pre-treatment such as sanding or preferably grit blasting can help improve adhesion. Mixing should be carried out for at least a few minutes to achieve a homogeneous blend without introducing air bubbles; if mechanical mixing is used, low speed is preferred. Application can be done in controlled steps to reach the desired layer thickness, and it is recommended to proceed to application as soon as possible after surface preparation. For storage, a dry environment at room temperature is targeted; a shelf life of 12 months is stated for unopened packaging, and opened containers are expected to be consumed within a shorter time.<\/p>\n","protected":false},"excerpt":{"rendered":"
