40 Hardness Platinum Silicone Glue For Crafts Jewelry Making 1:1 Silicone Rubber High-Strength Clear Silicone Adhesive

1.Description of Platinum Silicone Rubber

Platinum-catalyzed liquid silicone rubber is a two-component or one-component addition-curing liquid silicone rubber that uses platinum (i.e., a platinum complex) as a catalyst. It cures at room temperature or under heating conditions through an addition reaction with moisture in the air or with a co-reactant (such as hydrogen-containing silicone oil), forming a tough, high-strength, elastic silicone gel.

2.Advantages of Platinum Silicone Rubber

Environmentally Friendly and Non-Toxic:The reaction produces no by-products, and the cured material is odorless. Through formulation adjustments, products can achieve food-grade and medical-grade certifications.

High Transparency and Yellowing Resistance:The cured gel is crystal clear. Due to the stability of the platinum catalyst, it is resistant to yellowing over long-term use (its yellowing resistance is far superior to condensation-cure silicone).

Excellent Weather Resistance:It withstands high and low temperatures (typically operating from -50°C to over +200°C), UV radiation, ozone, and aging.

Outstanding Electrical Properties: It offers excellent insulation and is commonly used for potting and protecting electronic components.

Good Biocompatibility: It causes minimal skin irritation, making it suitable for products in contact with the human body, such as adult products, kitchenware, and artificial skin.

3. Typical application scenarios of Platinum Silicone Rubber
 

Platinum-cured silicone with a Shore A 40 hardness is the gold standard for creating flexible molds, especially suited for replicating complex objects.

Precision Industrial Part Replication:
Use: Copying parts with fine textures, undercuts, or complex geometries for small-batch production or prototype development.

Artwork and Sculpture Replication:
se:Reproducing plaster, clay, and resin sculptures, as well as for artifact restoration and replication.

Simulated Food and Confectionery Molds:
Use:Creating food molds for chocolates, candies, fondant, ice cream models, cake decorations, and more.

Resin Casting and Craft Molds:
Use:Producing casting molds for epoxy resin, UV resin, transparent soap, candles, and other crafts.

Concrete and Gypsum Precast Component Molds:
Use:Manufacturing molds for decorative cement tiles, gypsum moldings, reliefs, and other architectural decorative materials.

5.Packing of platinum silicone rubber
10Kg/set (A component 5Kg +B component 5Kg)
40Kg/set (A component 20Kg +B component 20Kg)
50Kg/set (A component 25Kg +B component 25Kg)

6.Precautions :

1. Do a small amount of testing before use, and then put it into use.

2. Do not add color or powder to the silica gel at will before testing. Do not contact with water, acid, alkali or other organic matter containing sulfur, phosphorus and nitrogen, so as not to affect the curing of silica gel.

3. This product is a platinum catalyst silica gel, which cannot be in contact with condensation type silica gel. Before using the silica gel, tools and containers need to be cleaned with thinner water.

         4. If you need to color, please add the color paste to component B by 2/1000, and stir evenly.
