Applications

The filler for emulational rubber, toys and so on.
The filling of adiabatic interlayer and the floating material in the salt atmosphere
The filling and repair materials for orthopedic surgery
Industrial rubber roller liner
Mattresses, pillows and other daily necessities

Usage

Before using, mixing well A and B separately
Weigh component A and B according to A: B = 10:1 by weight
Stir rapidly for 1 min, then pouring into the mould.
It is suggest that the best cured temperature is 20~25℃,which is conducive to stable operation.

Consistency

Specific materials, chemical compound, vulcanizers, and plasticizers will hinder the vulcanization of the product, mainly include:
▪ Organic tin and other metallic compound
▪ Silicone rubber contained organotin catalyst
▪ Sulphur, polysulfide, polysulfone or other sulphur containing articles
▪ Amine, ethyl carbamate or amine containing articles
▪ Unsaturated hydrocarbons plasticizer.
▪ Flux residues.
In order to ensure the applicability in the application, it is suggested to do small compatibility tests, if there is a question of whether one material will cause a hindrance to vulcanization or not. If there is a liquid or not vulcanized substance on the surface of an interrogative object and a vulcanized gel, it shows no compatibility, which will hinder the vulcanization.

Package and shipment

Component A and Component B are packed in 200kg metal barrel and 20kg plastic drum separately, or other specification package.
Store in dry place to avoid sun exposure and rain .The shelf life is 6 months with the original packing. Transport as non-dangerous goods
