Liquid oil-free soft silicone
Food Grade Organic Silicon Product Specifications
Food Grade Product Description
Cy-840 # It is a two-component additive silicone material that can be cured at room temperature or heated.
Characteristics of Food Grade Products
Numbering. Depth vulcanization is possible subject to product thickness.
Bottom line shrinkage (≤ 0.1%), reproduced products with high accuracy.
Chemical resistance, high temperature resistance can reach 300-500 degrees
Food grade, non-toxic and odorless.
High tensile, tear-resistant, turn a lot of times, not easy to deform.
Good fluidity, easy to perfuse, easy to operate.
Food grade silicone use.
Handmade soap molds cake molds diy molds cement composition molds cultural stone molds metal crafts and so on
Attention.
The above viscosity, operation time, hardness after curing can be adjusted according to customer requirements.
Eliminate product contact with water, phosphorus, tin and other materials, otherwise there will be sticky, not cured and other phenomena. The operation time should be separated from the condensing silicone container used.
Product use method.
1, silicone and curing agent mixed evenly. The appearance of the mold silicone is flowing liquid, the component is silicone, the component is curing agent. Example: Take100gramsA silica gel, add100gramsB glue (Note: a silica gel and b glue must be mixed evenly. If they are not mixed evenly, one piece of the mold will be cured and one piece will not be cured. Uneven silicone drying and curing will affect the service life and turnover of the silicone mold, and may even lead to mold scrap.

Usage and precautions
-WillA,BTwo components according to the weight of 1:1 mix evenly, vacuum defoaming can be watered. Room temperature (28 degrees) 30 minutes operation time, 4-5 hours of complete curing; heat60-120Degree, a few minutes can be completely cured.
Operation should be separated from the container in which the condensed silica gel has been used, and the silica gel should be operated at room temperature with tools that have not been used with silica gel.
