Varian Torr Seal Vacuum Equipment High Vacuum Epoxy, Good to 1x10-9 Torr

Varian Torr Seal Vacuum Equipment High Vacuum Epoxy
Agilent Varian Part Number 9530001

Epoxy resin conveniently seals leaks on any type of vacuum system or component. It is solvent-free and can be used at pressures of 10-9 Torr (mbar) and below, at temperatures from -49 F to 248 F (-45 C to 120 C) (bakeable temperature). Varian Torr Seal Vacuum Equipment High Vacuum Epoxy is packaged in two separate tubes; Part A Base Resin in an 82 gram tube and Part B Hardener in a 36 gram tube (Agilent Varian Item Number 9530001).

Directions for Use


    1. When mixing by hand, combine Part A (Resin) and Part B (Hardener) in equal parts for correct ratio. Mix thoroughly until the color and
    consistency are uniform. Tube Kits have been designed so that squeezing equal length beads of part A and part B will give the proper ratio.

    2. Mixing the adhesive just prior to use is recommended. The temperature of the separate components prior to mixing is not critical, but they
    should be close to room temperature.

    3. Heat buildup during and after mixing is normal. To reduce the likelihood of exothermic reaction or excessive heat buildup, mix less than
    900 grams (31.75 oz) at a time. Mixing smaller amounts will minimize heat buildup.

    1. Bonding surfaces should be clean, dry, and free of contamination.

    2. Once the adhesive is applied, the bonded parts should be held in contact until the part has developed handling strength (3 to 4 hours @
    77° F (25° C)) note: this can vary with different bond configurations. It is not necessary to clamp the parts unless movement during cure is

    1. Hardening time 1 to 2 hours @ 77° F (25° C.) Can also be fully cured with heat such as; 2 hours at a maximum temperature of 140°F
    (60° C.) Complete cure is obtained after 72 hours @ 77° F (25° C.)

    2. After 24 hours, approximately 90% of full cure properties are attained at room temperature.

    3. This product can also be cured for 1 hour @ 176°F (80° C) or 20 to 30 minutes @ 248°F (120° C.)

    4. Heat cures can be modified to achieve a desired degree of cure from handling strength to full cure.

Clean up
    1. It is important to clean up excess adhesive from the work area and application equipment before it hardens.

    2. Denatured alcohol and many common industrial solvents are suitable for removing uncured adhesive.

Note On Hardening
Epoxy resins are prone to solidification or crystallization. If this occurs, the product can easily be returned to a liquid state by immersing the tube in warm water, approximately 100° F (38° C ) for 30 minutes. Ensure all material is melted prior to use; gently re-warm if necessary. Allow the resin component to return to room temperature prior to mixing with the hardener. This warming process will not affect performance or product properties.
