Craft Mold Silicone is a liquid silicone mold developed specifically for flip molding crafts. It is composed of AB components, A component silicone, rtv 2 molding silicone rubber and B component curing agent. When used, the two components are mixed and stirred evenly according to a certain weight ratio to achieve room temperature curing and molding. The ratio of added silicone is 1:1, and the ratio of condensed silicone is tin curing liquid silicone100:2-3.
Features:
① Good flowability, low viscosity, and good operability;
② High and low temperature resistance, acid and alkali resistance, and aging resistance;
③ Good tensile strength and tear resistance, and the silicone mold produced does not deform;
④ Low linear shrinkage rate, easy demolding, and frequent mold turnover;
⑤ Color, hardness, viscosity, and operating time can be adjusted as needed.
Operation method:
① Mix and stir the silicone gel and curing agent in a weight ratio evenly (1:1 for addition molding and 100:2-2.5 for condensation type);
② After evenly mixing and stirring, the silicone gel is placed in a vacuum machine for vacuum exhaust bubble treatment. The advantage of doing so is to make the product smooth and bubble free. (Without a vacuum machine, the curing time can be extended to allow bubbles to naturally discharge, but the effect is not very ideal);
③ Spray (apply) a layer of release agent on the already made mold and mold frame, fix the mold in the middle, slowly and steadily pour the liquid silicone that has discharged bubbles into the mold frame until the silicone completely covers the mold, and then let it rest until it fully solidifies;
④ After the silicone gel of the mold is fully cured, demolding can be carried out, and the silicone mold can be removed for edge treatment.
⑤ It is recommended to leave the silicone mold for 24 hours before putting it into use, in order to achieve the best use effect of the mold.
Precautions:
① Silica gel and curing agent must be stirred evenly to avoid non curing of silica gel;
② The prepared liquid silicone should be used up as much as possible within the operable time;
③ When the original model produces glass, ceramics, or is coated with paint, the original model is evenly coated with shampoo solution or soapy water. After the water evaporates, the mold silicone is poured or brushed to facilitate better demolding;
④ Addition silicone and condensation silicone should not come into contact with each other, otherwise it may cause silicone "poisoning" and cause silicone not to solidify;
⑤ During the operation of adding silicone, it should not come into contact with water, impurities, organic tin catalysts, acids, bases, and compounds containing nitrogen, phosphorus, and sulfur. These substances should not be mixed during use to avoid the phenomenon of non curing of silicone.
The operational time and demolding time after the ratio of silicone and curing agent:
When the amount of curing agent added is 1%, the colloid will still flow after 2.5 hours and can be demolded after 6-8 hours;
When the amount of curing agent added is 2%, the colloid will still flow within 50-1 hour, and demolding can be carried out within 2-3 hours;
When the amount of curing agent added is 3%, the colloid will still flow after 28 to 30 minutes, and demolding can be carried out after 1.5 to 2 hours;
When the amount of curing agent added is 4%, the colloid will still flow within 10-15 minutes and can be demolded within 1-1.5 hours.
