● food grade silicone food grade AB AB is a two-component silicone Products · add molding silicone material that can be cured at room temperature can also be heat cured. ● food grade silicone AB Features * low shrinkage, the crosslinking process does not release low molecular weight, so the constant volume shrinkage of less than 0.1% - from product thickness limit, can the depth of curing and has excellent heat resistance, temperature You can reach 300-500 degrees · food grade, non-toxic, odorless, FDA food grade certification by High tensile strength, tear strength, turn mode more often · mobility, easy perfusion; can also be heat cured at room temperature curing easy to operate ● use food-grade silicone · AB for molding casting epoxy resin, polyester resin, polystyrene, vinyl, wax, large concrete structures, culture stone, concrete, etc., but also for metal crafts alloy automotive and other precision mold manufacturing, food-grade mold manufacturing. ● Use food-grade silicone AB and precautions · The A, B two components by weight of 1: 1 mix, after vacuum degassing can be watered. At room temperature (28 degrees) 30 minutes operating time, 4-5 hours to fully cure; heating 60-120 degrees, can be completely cured in a few very minute. · To use the operation and had condensation silicone separate container, use the unused room to operate this silicone silicone tool. ● food grade AB silicone technical parameters before mixing properties (25 ℃, 65% RH) component Y630 A Y630 B Color Transparent Transparent Viscosity (cP) 25000 3500 share 1.15 1.11 mixed properties (25 ℃, 65% RH) mixing ratio ( weight ratio) A: B = 1: Viscosity (cP) 1 Color Clear mixing operation after 8200 hours 25 ℃ (min) 30 initial curing time (h) 3 ~ 4 Hardness (Shore A) 30 Tensile strength (Kgf / cm2) 46 tear strength (kgf / cm) 15 Elongation at break (%) 520 * viscosity, operating time, the hardness after curing can be adjusted with the customer needs. ● food grade silicone AB Packing · Packing: A: 20kg 200kg B: 20kg 200kg ● food grade silicone AB Storage and Transportation · Storage period: 12 months (sealed, cool and dry place); ? These products are non- dangerous goods, according to general chemical transport.
