RTV-2 platinum-cured 1:1 addition-type liquid silicone rubber

"Why do Michelin pastry chefs prefer to give up metal molds?——Revealing how platinum liquid silicone can increase the success rate of cake demoulding to 99.9%!

1. Core advantages (5 major differentiated advantages)

(1)Food safety level guarantee
FDA certified, 3 times more resistant to oil and fat penetration than ordinary silicone, zero migration in long-term contact with cream/chocolate
Application scenarios: children's food supplement molds, precision parts of fondant cakes

(2) Nano-level detail reproduction
0.02mm ultra-fine texture reproduction capability (such as lace patterns, three-dimensional reliefs), surface roughness Ra≤0.15μm, sharp edges of cakes after demolding
Comparative data: The average distortion rate of traditional silicone molds is 8%-12%

(3)Extreme temperature adaptability
-50℃~250℃ wide temperature range performance:
✓ Directly into the oven (resistant to high temperature of 230℃ for 30 minutes without deformation)
✓ Supports rapid freezing (still flexible at -18℃)
Case: The success rate of French mousse cake demoulding is increased by 40%

(4)Revolutionary demoulding experience
Natural oleophobic surface + 0.01N/mm² ultra-low adhesion, complex geometric shapes (such as hollow chimney cake molds) do not require demoulding agents
User test: Caramel cakes with a sugar content of 30% can still be demoulded completely

(5)Industrial-grade durability
Tear strength ≥ 28kN/m, dimensional change < 0.3% after 2000 cycle tests, life is twice that of aluminum alloy molds
Cost calculation: Single-use cost is reduced by 62% in mass production

General parameters

2.Suitable cake types and application scenarios
(1) Exquisite shaped cakes
Fondant cakes: high-precision reproduction of complex patterns (such as lace and relief), demolding without damaging the surface.
3D three-dimensional cakes: suitable for special-shaped structures such as animals and buildings, the flexibility of silicone makes demolding easy.
Artistic decoration cakes: such as petals and leaves, LSR can perfectly retain 0.1mm level details.

(2) Cakes that require high temperature baking
Chiffon/sponge cakes: resistant to high temperatures of 230°C, evenly heated, avoiding local burning of metal molds.
Cheesecake: smooth edges after demolding, no water bath mold assistance required.

(3) Frozen/no-bake cakes
Mousse cakes: silicone remains elastic after freezing, easy to demold without cracking.
Ice cream cakes: resistant to low temperatures (-40°C), can be directly frozen and shaped.
Chocolate molding: uniform heat conduction, shiny surface without bubbles after demolding.

(4) Small batch creative desserts
Macaron shells: uniform size, suitable for standardized production. Mini cup cakes: One-piece multi-cavity design improves efficiency.

3.Main feature :

1. Environmentally friendly, non-toxic, tasteless, non-corrosive, passed FDA food grade, MSDS, ROSH and other certifications.

2. Low viscosity, good fluidity, convenient operation and easy pouring; it can be cured at room temperature or heated.

3. Excellent physiological inertia, waterproof, ozone resistance and aging resistance, high tensile toughness, and many mold turning times.

4. High chemical stability, high and low temperature resistance, can be used for a long time and maintain its performance at -55°C to 220°C.

5. No low molecules are released during the cross-linking process, so the volume remains unchanged, the shrinkage rate is as low as 0.1%, and the precision is high.

4.Mold making process of RTV-2 platinum-cured 1:1 addition-type liquid silicone rubber
(1) Prototype preparation
Clean and process the mold prototype to ensure that the surface is smooth and free of impurities.
(2) Mixing and degassing
Mix components A and B in a 1:1 ratio, stir evenly and vacuum degas to avoid bubbles affecting the quality of the mold.
(3) Pouring and curing
Slowly pour the mixed silicone rubber onto the prototype to ensure that the details are completely covered.
Cure at room temperature or under heating conditions, usually for a few hours to a day.
(4) Demolding and post-processing
After curing, carefully demold and check the integrity and accuracy of the mold.
Surface treatment or secondary curing can be performed as needed.

5.Packing and shipping:
10Kg/set (A component 5Kg +B component 5Kg)
40Kg/set (A component 20Kg +B component 20Kg)
50Kg/set (A component 25Kg +B component 25Kg)

Packed in iron drum or plastic drum, transported as non-dangerous goods, sealed at room temperature 25°C, and protected from acid and alkali impurities, the storage period is 12 months.

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.
