So funny, liquid silicone can change the hardness like this!

With the development of the times, more and more environmentally friendly materials have attracted people's attention. One of the most dazzling is probably liquid silicone.

You may have used liquid silicone to make stones and plaster molds, or you may use it to produce silicone sex dolls, human organs, and sex products, or you may use it for waterproofing and moisture-proof potting of electronic components and HEPA air-conditioning filters.

But do you know that you can get a new hardness after mixing two kinds of silicone rubber of the same type? Isn't it amazing?

For example, adjust to 30 shore A hardness? Mix with 20A and 40A by 1:1,

adjust to 25 shore A? then use E620 (20 A) :E640 (40 A) =3:1, but be sure to stir again.
Otherwise, it may cause some parts to be different.

E620 A component is taken 300 grams, E640 A component is taken 100 grams, mixed, stirred evenly
Take 300 parts of component B of E620, take 100 grams of component B of E640, mix and mix well.
