RTV Manual Molding design Silicon Rubbers description: RTV manual molding design silicon rubber has the features of resistance to deformation, good tensile strength and low shrinkage. And times of reproduction are up to customers need. RTV Manual Molding design Silicon Rubbers operations: First and foremost, you should process and prepare model or product which is duplicated, and then you should combine certain amount of the silicon rubber with 2-3% solid curing agent. Mixing them evenly and prepare for using. RTV manual molding design silicon rubber can be solidified and formed in 2-3 hours. (Note: Our company does not recommend you to add silicone oil. If a special soft silicon mold or fine detailed and complex patterns product is required, 5%-10% silicone oil can be added to soften the mold for easier demould.) .
