 PRODUCT DATA SHEET

‘SAFE’ Putty P-325

 PRODUCT DESCRIPTION

Safe Putty P-325 is moisture resistant putty consisting of a solvent less Varnish, filler and catalyst. These three components are to be mixed at the time of application and applied by knife or spatula.

 APPLICATION AREAS
• Filling voids and spaces in traction motors and generators.
• Sealing the ends of open margins of magnet and transformer coils.
• Filling voids and spaces in AC/DC rotating equipment and other-electrical equipment.
• General purpose high heat conducting Sealant & Epoxies
.
 SALIENT FEATURES
Thermosetting putty - Cures to a tough. rigid, heat conducting infusible solid which bonds well
To most surfaces with very low shrinkage and high resistance to cracking.

Uses solvent less Varnish - Void free Sealant & Epoxies of pores and spaces protects against oil, dirt, moisture etc.

High bond strength - Provides excellent mechanical strength at elevated temperatures.
Excellent Electrical Properties - Improved resistance to a high moisture environment.


 APPLICATIONS FIXING

When making P-325, safe Putty. the entire contents of the two compartment container must be thoroughly mixed. (The putty will not harden properly unless this is done) Do not apply heat to the can while or after mixing otherwise jollification will occur.

 STORAGE

The mixed putty has a storage life of 3-4 days at 25⁰C refrigerated at 5⁰C it will remain usable for several weeks. Care should also be taken not to contaminate the putty with foreign materials.

 USE 

P-325, safe Putty, May applied with a conventional putty knife or pressure gun. The putty will not flow either hot or cold and hence, should be pressed into deep sections to insure solid filling.

Al though P-325 bonds well to most surface. It is suggested that the surface be fee of oil or grease to obtain the most effective bonding.

Cure Time

For optimum or maximum electrical and mechanical properties, the following curing times are suggested:

8 hours at 90⁰C
Or 6 hours at 125⁰C
Or 4 hours at 150⁰C
