Silicone Foam RTF-764 - 2 parts liquid

This series of products is two-component condensation liquid silicone rubber. It can be harden to medium density foam formation with the hardener is added to the silicone at the room temperature, The formation of foam will be lasted 20 minutes during the a chemical reaction between hardener and silicone.
Product Feature:
A, Good emulsification
B, Excellent foam stabilization
C, Excellent resistance to high temperature and oxidant
D, Reduce surface tension between molecules
E, Non-toxic, non-corrosive, non-hazardous
Characteristic
A, It can be form a medium density elastic foam;
B, Hardened with the room temperature;
C, There aren’t any solvents nor smell
D, For most of metal, glass and metal foil without glue;
E, The ability to produce high quality bonded to the substrate with the use of adhesive
F, Chemical foam without the use of CFC
F, Additive filler
Usage: The application includes the following recommendation, but not limited to these.
A, Thermal insulation of the CAST scene.
B, Small molding parts.
C, Silicone Foam, Silicone sponge
D, Application of heat treatment of metal foil and the film store of cutting hot mirrors
3, Standard product data and the character before harden.

Application:
A．Cases of mixed a:b to 10:1. Hardened interval of time to cool the base adhesive, extended hours of operation, but not frozen, hardening time can increase of 50 degrees centigrade heat be reduced
B，When manually mixed, with a clean, flat spoon - shaped blade or paint stirrer, material attached to the bottom edge of the container and should be in mixed cycle weary into the master element twice.
C，The use of dynamic mixer, cycle typically takes 30 seconds to achieve thorough mixing of high speed stirring to avoid extended period of time, so will cause the heating of materials and result in dumping shorten the timetable.
D，Design of automatic injection machine for quantitative, mixing and preparing silicone foam rubber material of flavonoids, will reduce the required production, in particular to the production worth investing in.
E，Quantitative and preparation : rtf-764 silicone foam rubber of Flavonoids by the standard quantitative mixing device for the preparation of the second component, evenly and thoroughly mix is necessary in order to produce high quality foam, during the mixing process, you should avoid excessive heat, select the device is based on the individual application requirements.
Application and hardening time expired
Under the 25 C, rtf-764 silicone foam rubber of Flavonoids will take about 1.5 minutes of time, expansion in hardening agents after 5 minutes, resulting in foam can be used within 30 hours.
