Product Description
BLUESIL RTV 141 A&B E5 is a two-component, addition-curing RTV-2 silicone that cures at room temperature to a transparent elastomer and is used for potting and protecting electronic and optoelectronic components.
Are you planning a potting project with BLUESIL RTV 141? Please tell us the assembly group, quantity, country of delivery, and desired finish. We will check the product, packaging, and availability for your quotation. Request a quote for BLUESIL RTV 141.
After mixing the two components, BLUESIL RTV 141 A&B E5 forms a relatively low-viscosity, colorless liquid that cures into an elastic, transparent material. The reaction does not release heat, and curing can be accelerated by heating.
Addition-curing RTV-2 silicone with good optical transmission and good pourability, designed for the protection and insulation of light-sensitive and optoelectronic components.

Important Notes
- Curing may be inhibited by contact with sulfur-containing rubbers, metal salt-catalyzed RTV, tin-stabilized PVC, or amine-cured epoxies; if in doubt, test beforehand.
- Curing at room temperature results in low linear shrinkage (approx. 0.4%), but prevents the vulcanizate from achieving its optimal mechanical properties.
- The currently valid Elkem data sheet (TDS and SDS) is authoritative, which we will be happy to send you.
Frequently Asked Questions about RTV 141
Practical application and design questions, answered by SILITECH.
100 parts RTV 141 A E5 to 10 parts RTV 141 B E5 (parts).
The pot life of the catalyzed mixture is approx. 4 h at 25 °C.
Yes, degassing at 30 to 50 mbar is recommended to avoid air bubbles; the product must be degassed for a particularly long time.
Adhesion is achieved on most substrates with the primer PRIM PMB 821; the potting should be carried out within four hours after the primer has dried.
