Crafts Molding Silicone

A number of custom, Do-It-Yourself craft and hobby projects can be completed with the help of GC Silicone molding materials. Any decorative object (e.g., resin jewelry, model trains, custom tiles, small figurines, wall art, much more) can be molded using silicone or polyurethane mold rubber and then replicated in any number of materials, including plastic, concrete, plaster, foam and more.

Popular mold making silicone rubber is C-820 and C-825, which is at in-cured silicone rubber with a 100A:3B mix ratio; measure with a digital scale.

Typical general characteristics	Inspection Method	Value
Product data (Catalyzed A+B)		C-820	C-825
Hardness	Shore A	20±2	25±2
Mix Ratio	A:B	100:3	100:3
Color	/	White	White
Pot life	25 °C (77F)	30-40mins	30-40mins
Curing time	25 °C (77F)	3-4 hours	3-4 hours
Mixed viscosity		16000±1000	20000±1000
Tear-strength	kg/cm	20±2	22±2
Tensile-strength
Elongation	%	400±50	450±50
Shrinkage	%	≤0.3	≤0.3

Note: This is a 100A:3B mix ratio product that must be measured by weight. The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise.

Low viscosity,great flexibility,Extra low shrinkage,Chemical resistance,release properties, Easy to work with,High tear strength,Heat Resistance,various color is available,High reproduction rate

When stored at or below 32°C (89.6°F) in the original unopened containers, C-8 series Silicone Base and its Curing Agents have a usable life of I0 months.

Silicone base:1kg/drum; 20kg/drum;25kg/drum;200kg/drum.

Curing Agent: 30g/bottle; 1kg/bottle
