Whether you are using a 1:1 or a 10:1 mold making system the proper mix ratio is key to have the strongest mold with the longest life possible. Under catalyzing will prevent the silicone from achieving the ultimate strength and hardness while over catalyzing can cause the silicone to become hard, brittle, and virtually un-useable over time. GT Products mold making silicones are known for their long library life but to achieve the ultimate longevity then mixing by weight and not by volume is of the highest importance.
To ensure that all of our customers get the most out of our silicones GT Products is now offering low cost but extremely accurate scales. These scales measure in grams which is always our recommendation for accuracy and will weigh up to 11 pounds. The scales will be sold for $50 and are currently in stock. If you need more information then please do not hesitate to call us.
