Loctite 4090 is a two-component, general-purpose adhesive that provides a very fast fixture time at room temperature. It is designed to bond a variety of substrates including metals, most plastics and rubbers. Loctite 4090 provides good temperature and moisture resistance which also makes it suitable for applications in high temperature/humidity environments. Its thixotropic nature makes it suitable for applications where good gap filling properties on rough and poorly fitting surfaces are required.
