The pioneering adhesive formulators at Panacol-USA have found methods to create more robust adhesives that possess greater cohesive strength with improved adhesion to a broader array of plastic substrates. Tangent’s expertise in light curable adhesives has led to the development of much desired soft, flexible adhesives that can be cured under low intensity UV and UV/Visible light. Despite using lower light intensity, Tangent’s adhesives fully cure in seconds, and exhibit dry, tack-free surfaces. These low intensity curable adhesives are part of Tangent’s LEDcure product line.
Tangent’s adhesives for plastic bonding can be cured with UV, UV/Visible, or only Visible light wavelengths. High strength bonds are achieved with a wide variety of substrates, including combinations of polycarbonate, acrylic, ABS, polyurethane, polyethylene, stainless steel, and glass. They are well suited for assembling consumer appliances and electronics, screens and displays, product packaging, and a host of other applications involving combinations of plastics, metals and glass.
The following table provides a quick summary of our selection of light curable adhesives best suited for plastics and dissimilar materials assembly. In the event that these standard products do not satisfactorily address your performance requirements, Tangent will investigate other solutions that include adhesive development specifically tailored to the complexity of your application.
