This Silicon Moulding Rubber 1.05kg is a two-part moulding system perfect for casting resin and plaster objects. It is ideal for creating fine detailed moulds for casting resin jewellery, figurines, plastic models and prototype parts. Use Silicone Moulding Rubber 1.05kg in conjunction with the Claymate Mould Making Clay and Casting Resin Clear for a hassle-free resin casting experience. Also great for casting plaster and wax items.

Once cured this silicone is strong. It has a high tear strength and great elasticity making it perfect for casting objects with large undercuts. It has excellent long-term stability so your mould will last for years to come. High resistance to casting resins means demoulding your object is effortless.

Safety: Always wear a mask, gloves and eye protection, and work in a well ventilated area. Make sure you are working on a table covered with plastic sheeting to prevent damage.

Additional Information

How to use:



Step 1: Create a flat backed object using the Claymate Mould Making Clay, or select an object with a flat side. NB: Glossy objects will cast a glossy finish, matte objects will cast a matte finish.







Step 2: Place the object down onto a flat working surface. To prevent damage to the working surface you can cover it in plastic sheeting or food wrap.











Step 3: Roll out a slab of Claymate Mould Making Clay to prepare a wall which will surround your object and contain the Silicone Moulding Rubber mixture. NB: This wall needs straight edges, must be 1cm thick, 1.5cm taller than the highest point of your object, and must sit 1cm away from your object.











Step 4: Use more Claymate Mould Making Clay to seal the wall to the board to prevent leakage.







Step 5: Silicone Moulding Rubber is a two part solution, Part A - Silicone Moulding Rubber and Part B - Catalyst. Both parts need to be individually weighed before mixing using digital scales.



Weigh out the required quantity of Part A, enough to fill your Claymate mould. Calculate 5% of this weight. This equals the amount of Part B that is required. For example if Part A = 100g you will require 5g of Part B. Mix both parts together thoroughly with a Popstick.



Step 6: In a slow thin stream, pour mixture into one corner of the mould to reduce air bubbles. Air bubbles can get stuck in intricate features of your object and ruin your mould.







Step 7: Fill your mould until the silicone is 1cm above your object. This can be tested using a Popstick.



Step 8: Leave to set until silicone is firm (15 hours minimum).







Step 9: When set, gently peel away Klean Klay from around your mould. Then pull the silicone mould off the board and release your object from the mould. You may need to trim excess silicone from your mould.
