SATOP®LSR2040 Two part Liquid Silicone Rubber

SATOP®LSR2040 Liquid Silicone Rubber

Product Description:

This product is made of high temperature curing two-component addition type liquid silicone rubber, designed specifically for precision mold fabrication, and fiber glass sleeving coating. After curing have the dimensional stability, good release properties, tear-resistant high strength, low linear shrinkage, excellent ozone and UV aging resistance, non-toxic, tasteless, and has good biocompatibility. This product is easy to use, compound viscosity is moderate, high temperatures can be quickly cured.

Characteristics after curing:

  1. Quick curing at high temperature, easy to use;
  2. Addition-curing, does not release any gases;
  3. Superior mechanical properties, low linear shrinkage;
  4. Excellent ozone and ultraviolet resistance;
  5. Excellent electrical properties, good chemical stability;
  6. Moisture-proof, waterproof, resistant to ozone, weather-resistant.

Operation caution:

  1. Products can be added solvent used as coating products. Recommended by the solvent are toluene, xylene, and petroleum ether. When you use Mix part A and solvent evenly, and then add the part B, continue to stir well beforeuse.
  2. Mixing should pay attention to the same direction, otherwise, it will stir with too much bubble; Borders and the bottom of the container sizing material should also stir well, can appear otherwise stir caused by uneven local not curing phenomenon.
  3. Casting the product vacuum pumping, remove again bubble can improve after curing products comprehensive performance.
  4. Low temperature willcause the curing slowly, if necessary can improve the heating temperature or prolonged curing time. Also can improve the amount of curing agent to shorten curing time.
  5. LSR1318 with contain N, S, P element of compounds and some heavy metal ion compounds, will appear difficult contact curing or not curing phenomenon. These heavy metal ions including Sn, Pb, Hg, Bi, As, etc.
