MERECO METASIL 5060 THERMALLY CONDUCTIVE SILICONE
RTV FOR ELECTRONIC HEAT TRANSFER APPLICATIONS
Mereco Metasil 5060 is a two-component, solventless,
addition curing silicone RTV material specifically designed for
applications where a thermally conductive, thixotropic, medium
durometer material is required. Metasil 5060 has high
temperature and chemical resistance with excellent flexibility and
low shrinkage.

Handling Instructions: Weigh 100 parts of activator to 100
parts resin. Mix for a period of time until mixing is complete.
Degas for 5 minutes under a vacuum of 25-29 inches of Mercury. Apply
material. Cure according to the cure schedule desired. If dual
cartridges are used, the material may be directly applied using a
static mixer.
Note: Certain substances may inhibit the cure of
Metasil 5060 by direct or indirect contact. Metallic salts,
butyl, PVC plasticizers, chlorinated rubber, amines and sulfur
containing materials may all inhibit the cure.
Storage and Handling: Mereco Metasil 5060 has a
shelf-life of six months from date of shipment when stored in
original unopened containers at a temperature below 25°C.

METASIL 5060 is available in pint, quart, 2 quart, and 2 gallon kits
as well as 50ml, 200ml, and 400 ml dual cartridges.
Refer to Mereco TAB 3-641 for proper operation of 50cc dual
cartridges using a manual dispenser. Pneumatic dispensers are also
available. For 200 ml and 400ml dual cartridges pneumatic dispensers
are recommended if small quantities of material are to be applied.
Contact Mereco if further information is required. |
