Lace fondant mold food grade silicone food grade silicone characteristics and uses of the product of high quality silicone, processing the scientific formula, advanced technology from. The product has a soft, stable temperature performance characteristics. Widely used in various food cake molds, candy molds, technical ceramics, printing, human organs, household appliances, lighting products. Food-grade silicone main technical parameters Model / Item Y625A / B Appearance (A component) white / transparent appearance (Component B) Transparent / red A, B component ratio of 1: 1 A component viscosity Pa.S 60 operational time (25 ℃) min 30 curing conditions (℃ / h) 25 ℃ / 24 or 80 ℃ / 0.5h ~ 1h Density / g · cm-3 1.1 Hardness (JIS A) 25 Elongation at break /% ≥300 tear strength / KN · m-1 ≥20 tensile strength / Mpa ≥5.0 linear shrinkage / 0.1% food grade silicone to use a hybrid: the gum base and hardener by weight ratio of 1: 1 mixture, mixing either manually or using equipment. 2, degassing: glue mixture before filling the mold should be degassed. A small amount when used in a vacuum dryer, under vacuum, compound volume can be increased 4-5 times (foam), and therefore, the container should be larger than the volume of degassed gel volume 4-5 times, after a few minutes gel volume returned to normal, when the surface no bubbles escape (about 10 minutes) to complete. 3, surface treatment: surface mold surface or potting compound to be contacted with a liquid paraffin and the like as a releasing agent. 4, curing and stripping: mixing the degassed plastic material is placed 120 ± 5 ° C cure bake 30 minutes, 60-70 ° C for 2-3 hours bake curing, room temperature curing time is 24Hr, curing temperature and time may be According to the process conditions. Food grade silicone packaging, storage and Notes 1, the product 25KG / barrel, 200KG / barrel metal pail 2. The product is non-dangerous goods, should be sealed and placed in a cool place, to prevent rain, sunlight exposure . 3, the product storage period of six months. If the viscosity increases during storage under shear stress (mixing) can restore their mobility. It is recommended to use the first plastic material in the container stir, then add hardener mix. Extended reinspection after passing can still be used. 4, in the course of the operation should avoid contact with condensation silicone rubber curing agent. May cause non-vulcanized rubber as well as amines, sulfur, phosphorus compounds, and some metal salts.
