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