Silicone conformal coating

Leslie_Gordon — Wed, 18 Nov 2009 11:48:03 -0600

A rapid tack free, ready-to-use silicone conformal coating, Master Sil 773 provides excellent protection to electronic circuitry in high humidity environments as well as upon exposure to shock and vibration. It cures quickly at ambient temperatures to a highly flexible, transparent, low hardness silicone coating. The coating maintains its low modulus over the remarkably wide temperature range of -65°C to in excess of +200°C. Master Bond, 154 Hobart St., Hackensack, N.

Non-biofouling coating technology

Leslie_Gordon — Wed, 18 Nov 2009 11:27:08 -0600

VitroStealth is a non-biofouling (NBF) coating technology. The coating is scratch resistant and reduces unwanted protein absorption and cellular adhesion on surfaces. Application includes pre-analytical blood collection devices where VitroStealth coating eliminates surface mediated hemolysis and leads to clean, reproducible and thus reliable serum or plasma samples for the clinical laboratory. In diagnostics, the coating increases signal to noise ratio as the analyte is not partially lost by adsorption to the surface of the device.

UV-light-curable silicone

Leslie_Gordon — Wed, 18 Nov 2009 11:07:02 -0600

Cure-Point 9440-A/B UV/visible light-curable silicone potting and sealing material is intended for applications where fast cure, enhanced thermal performance, and room-temperature shadowed-area cure are required. The material withstands long exposure to temperatures ranging from below -40° C to above 200° C. This makes it superior to RTV silicones and heat-cure silicones which require longer cure times or elevated temperatures to cure.

Key points:
• Brass inserts’ high thermal conductivity means faster heating and insertion into plastic parts.

• Brass is easier to machine than stainless steel, which lowers manufacturing costs.
