Onto™ EP1132 is a range of functional surface treatments that can be used to promote adhesion of two-part polyurethane and epoxy coatings to difficult-tobond substrates such as engineering polymers, high performance (speciality) plastics and thermoplastic composites. The treatment can be applied to a substrate from solution using a range of coating methods to form a functional layer of material that is strongly bonded to the substrate surface. The new surface functionality is chemically compatible for bonding to polyurethane and epoxy coatings and the treatment has been shown to prevent delamination even under severe weathering conditions.

- Processing and Treatment
All Onto™ materials are precursors to highly reactive carbenes. In the unactivated form they are stable to heat and light, and therefore Onto™ EP1000 can be shipped and stored in this stable form. The treatment is compatible with a variety of solvents and formulations to suit specific applications can easily be designed. An environmentally friendly alcohol/water mixture is ideal, and harmful solvents can be avoided in many applications. Once chemically activated, the treatment can be applied from solution to a substrate using standard wet-coat techniques such as dip, spray, flexo, K bar (meter rod), metred slot, gravure, spin and ink jet. The versatility in processing enables the use of Onto™ EP1000 treatments on a variety of material forms including sheets, films, powders, fibers and fabrics. A curing stage is required to generate the highly reactive carbene species, which then reacts and forms a bond to the substrate surface. This functional layer is now permanently bound to the surface, and any following treatment (lamination, coating, printing, etc) can be completed offline. This is in stark contrast to corona or plasma treatment and even some wet primer treatments, where longevity can be an issue and it is often necessary to bond the substrate within hours or days of treatment.
