● product introduction

 

Jc-s625 is a two-component condensation type organic silica gel material produced by Shenzhen Jucheng Silicon Technology Co., Ltd.

 

 

 

● product features

 

·It has low shrinkage and does not release low molecules in the process of crosslinking, so the volume is unchanged and the shrinkage is less than 0.3%

 

·Not limited by product thickness, it can be deeply solidified

 

·With excellent high temperature resistance, the long-term temperature can reach 120 degrees

 

·Environmental protection, ROHS certified

 

·High tensile and tear resistance, especially strong physical properties

 

·Room temperature curing, faster molding speed

 

·Easy to operate, strong fluidity. Exhaust bubble is very easy.

 

·After curing, the surface is dry and not sticky.

 

Strong adhesion

 

 

Purpose

 

·The condensed liquid silica gel is used to copy various fine grain resin crafts or gypsum crafts, soap silica gel mold, candle silica gel mold, airport runway filling silica gel, toy mold silica gel, copy crafts mold, brush mold, filling mold, slice mold, etc.

 

·Other types of condensed silica gel are also used for electronic filling silica gel, pad silica gel, insole silica gel, liquid silica gel for automobile tire mold.

 

 

 

 

● usage and precautions

 

·Mix components a and B evenly according to the weight of 100:3, fill the mixed exhaust foam in 30-60 minutes, and demould in 2-3H;

 

·The proportion of adding curing agent should be accurate, and it can not be added by feeling, otherwise the curing time and operation time will be affected.

 

·Stir evenly.

 

·Do not use diluent on the market, such as xylene, etc. to dilute, and change viscosity, etc., contact the engineer of poly silica gel in time, and change after consultation.
