● product introduction

 

Jc-j640 is a two-component addition molding organic silica gel material produced by Shenzhen Jucheng Silicon Industry Technology Co., Ltd. with room temperature curing characteristics.

 

 

 

● product features

 

·It has low shrinkage and does not release low molecules in the process of crosslinking, so the volume remains unchanged and the shrinkage is less than 0.1%

 

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

 

·Excellent high temperature resistance, long-term temperature can reach 220 degrees

 

·Environmental protection, non-toxic and tasteless, FDA food grade certification

 

·High tensile and tear resistance, especially strong physical properties

 

·Room temperature curing, heating curing, faster molding speed

 

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

 

·After curing, the surface is dry and not sticky. The product effect is excellent.

 

 

Purpose

 

·Copy all kinds of fine grain resin crafts or gypsum crafts, make all kinds of cake silica gel mold, candy silica gel mold, chocolate silica gel mold, soap silica gel mold, candle silica gel mold, kitchen handle, human skin imitation, artificial limb, etc.

 

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

 

 

 

 

● usage and precautions

 

·Mix components a and B evenly according to the weight of 1:1, fill the mixed exhaust foam in 30-60 minutes, and demould in 2-3H;

 

·During operation, it shall be separated from the container using overcondensated silica gel, and the silica gel shall be operated with the unused silica gel tool at room temperature. Avoid other halogen and heavy metal elements contaminating platinum catalyst, resulting in non curing or sticking after curing.

 

·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.
