1.DESCRIPTIONS
YOZHO@ 2556 trade mark silicone rubber is an addition-cure liquid
silicone material which can be used to make transparent, heat- and
water-resistant elastomers.
2.FEATURES
*medium viscosity and good flowability
*hear accelerated curing
*good transparent property
*good adhesive ability
3.APPLICATIONS
Mainly used to make trade marks of textiles, and also can be used
as trademark and anti-skid coating of metal, paper, plastic and
leather.

5.HOW TO USE
A.MIXING
Mix A and B to stir thoroughly. The weight ratio of A to B is
100:10;
B.DEGASSING
Degassing at vacuum for minutes, it is needed to degas several
times
C. OPERATION
After degassing, the mixture can be used to fill, encapsulate, make
marks, etc.
6.PACKAGE
The products are packaged as Part A and Part B components:
Part A：5-kg/ bucket;20-kg/ bucket; 25-kg/ bucket
Part B：0.25-kg/ bucket; 0.5-kg/ bucket; 1-kg/ bucket;
7.COMPATIBILITY
Certain materials, chemicals, curing agents and plasticizers can
inhibit the cure of addition-cure silicones. Most notable of these
include:
I. Organotin and other organometallic compounds
II. Silicone rubber containing organotin catalyst
III. Sulfur, polysulfdes, polysulfones or other sulfur- containing
materials
IV. Amines, urethanes or amine-containing materials
V. Unsaturated hydrocarbon plasticizers
VI. Some solder flux residues
If a substrate or material is questionable with respect to
potentially causing inhibition of cure, it is recommended that a
small scale compatibility test be run to ascertain suit-ability in
a given application. The presence of liquid or uncured product at
the interface between the questionable substrate and the cured
silicone indicates incompatibility and inhibition of cure.
