Revolutionary UV/Visible Light Curing Silicone For Deep Potting and Sealing

Rocky Hill, Conn. - July 13, 2005.... Revolutionary next generation silicone technology from Henkel Corporation cures tack free in seconds to a depth of two inches upon exposure to UV or high-power visible light. These one-part Loctite® Nuva-Sil® silicones are ideal for deep potting, encapsulation, environmental protection, and sealing.

Patented next generation Loctite® Nuva-Sil® products offer superior weather, temperature, and moisture resistance. Translucent in appearance, the silicones will not degrade or yellow on long-term exposure to light. All three next generation silicones offer a built-in fluorescence detection system that allows quick, easy, automatic quality inspection. Complete cure requires only low cost, highly safe visible light cure equipment or UV cure systems. Loctite® Nuva-Sil® silicones also feature a secondary room temperature moisture cure mechanism for adhesive in shadowed areas.

Next generation products include: Loctite® 5031(TM) Nuva-Sil®, a self-leveling liquid that flows easily under parts for potting, encapsulation and sealing applications; Loctite® 5039(TM) Nuva-Sil®, a semi leveling paste that is ideal for gasketing and sealing, forming an excellent bead with minimal knit lines or seams; and Loctite® 5033(TM) Nuva-Sil®, a thixotropic paste for gasketing, sealing and potting applications that require a full-bodied material.

Next generation Loctite® Nuva-Sil® products offer improved stability and a longer shelf life than their predecessors. These non-conductive silicones are ideal for applications requiring an elastic seal and excellent degradation resistance, including general industrial, medical, surgical, lighting, optical, electrical, and electronic applications.
