Multi-Purpose Polyurethane-Based Adhesives

View of vehicle spoiler bonded with SikaForce Assembly Adhesive Solution

SikaForce® two-component (2C) polyurethane-based adhesives are used to bond various combinations of plastics, metals (coated and uncoated), and composites, primarily in assembly processes. They typically consist of a polyol-based resin and an isocyanate-based hardener, which can be processed using commercial metering and mixing machines. They cure at room temperature; however, the process is accelerated at higher temperatures (up to a max. of 100 °C).

Main Material Properties

Sika offers two types of 2C adhesives. Our engineers can help you identify the right adhesive based on the requirements of your application. 

SikaForce® adhesives require a metering machine and a dynamic or static mixing system to properly mix the two components. Our System Engineering team is available to provide advice on selecting and setting up a suitable pump system and mixing unit.
