HY-F667 Product Specifications
Product introduction
·HY-F667 is a two-component addition silicone foam, room temperature curing. It will be white flexible elastomer after curing.
Product features
·With excellent resistance to high and low temperature, weather resistance, chemical stability, excellent biological inertia
·Food grade, non-toxic and tasteless
·Liquidity, easy to perfusion; can be room temperature curing, easy to operate
·high foam expansion;foam uniformity, good stability
Application
·For electrical and electronic components and mechanical parts of the potting, can also be used for packaging materials, dolls filled with human, as well as cushion and mattresses and other production.
Operation method and notice
1.Preparation
Prepare clean mold (for the anti-stick mold recommended in the mold surface evenly coated with a thin layer of Vaseline class release agent), stirring container, electric mixer, stopwatch.
Test of the operating time: A, B rubber to 1: 1 (each 10g or so) in the proportion of plastic cup, immediately manual mixing, until the compound no liquidity, the time down is the operating time.
2.Mixing
Pour A, B rubber to 1: 1 ratio in turn into the mixing container, start the electric mixer to stir evenly into the mold.
3. Notice
Recommended the inventory of silicone:
Inventory(g)=Mold volume cm 3/(foam expansion-1)
Determination of electric stirring time:
If the operation time is 4 minutes and the time required for the compound to fill the mold cavity is 2 minutes, the machine stirring time can be set 90-120 seconds(The stirring speed is set to 1000 R / MIN, and the stirring time is decreased correspondingly when the stirring speed is higher).
Generally, the longer the mixing time, the better the foaming effect.
Stirring temperature has an effect on the foaming, to avoid the temperature is too high.
Foam effect will be better in Closed mold.
