How to Choose the Right RTV Silicone for Your Mould-Making Projects
Selecting the appropriate room-temperature vulcanising silicone for your mould-making endeavours requires careful consideration of multiple factors that will ultimately determine the success of your casting projects. Whether you’re a hobbyist creating detailed miniatures or a professional manufacturer producing industrial components, understanding the key characteristics of RTV Silicone will help you make informed decisions that save time, money and frustration.
Understanding Shore Hardness
The hardness of your silicone rubber directly impacts the durability and flexibility of your finished mould. Shore hardness is measured on the A scale for softer materials, with values typically ranging from 10A to 50A for mould-making applications. Softer silicones around 10A to 20A excel at capturing intricate details and work brilliantly for delicate models with undercuts, as the flexibility allows...
