Henkel expands line of Loctite medical device silicones

Article Type: New products From: Pigment & Resin Technology, Volume 38, Issue 3

Henkel has introduced a line of single-component light and moisture curing silicone adhesives designed for use on medical devices that incorporate silicone materials or require highly flexible bond joints or coatings. All three products in the line cure within 30 s on exposure to a suitable ultraviolet – UV/visible light source.

These medical silicone adhesives eliminate part racking and allow immediate quality control testing. To ensure robust assemblies, the products offer high-bond strengths on silicone and plastics including polycarbonate. The silicones demonstrate tear strengths in excess of 50 pounds per inch and elongation of more than 140 percent in the cured state, resulting in tough, yet flexible bond lines. These adhesives are ideal for use on catheters, respiratory devices and connections, medical tubing and tracheotomy devices.

Loctite 5055 is a low viscosity, light yellow, transparent liquid that offers adhesion to polycarbonate and tensile strengths of nearly 1,500 psi. Offering a similar uncured appearance, medium viscosity Loctite 5056 offers heat and humidity resistance in its cured state. These two new light cure silicone adhesives join Loctite 5240, introduced earlier this year. A UV/visible light-curing silicone, Loctite 5240 offers a secondary moisture cure that takes place in shadowed areas in 24-72 h. This adhesive cures to depths of 0.75 in. and delivers a colorless bond line.

All three Loctite products meet strict ISO-1093 biocompatibility requirements, making them ideally suited for medical device assembly.
