Techsil Launches CRTV5120, a 1C Silicone Rubber for Sealing Applications in Electronics

CRTV5120 is an innovative one component silicone rubber manufactured by Momentive, Techsil are Momentive’s UK distribution partner, and it has been engineered for electrical semi-conductive applications. CRTV5120 is an easy to use, one component fast-cure soft spreadable paste, which cures at ambient temperature (tack-free time 20 minutes, full cure overnight) or more quickly at elevated temperatures. It can be easily applied to provide primer-less adhesion to many metals, ceramics, plastics, glass & other substrates generally without the need for a primer. The cured materials exhibit environmental resistance and superior physical strengths as well as semi electrical conductivity.

The techy stuff says it offers a resistivity between 200 to 800 ohm-cm, hardness is 35 Shore A, elongation is 250% and tensile strength is 2.0 MPa. This high performance semi conductive silicone adhesive was designed to resistant high temperatures and still offer flexibility at low temperatures (-60°C to 205°C). Due to its paste consistency, CRTV5120 will only flow with external pressure making it suitable for use on horizontal, vertical and overhead surfaces at a thickness of up to 10mm as it is a moisture vapour cure system. Storage stability in original closed containers at ambient temperatures is 6 months.

Momentive CRTV5120 is ideal for industrial applications where electrical semi-conductivity characteristics and final design of the finished product is of paramount importance. Typical applications include gaskets and seals for electronic parts, which need EMI/RFI Shielding & related applications, for environmental protection and long term flexible sealant integrity.
