Product Features & Advantages

Adopting a highend hightemperature resistant formula system, it enhances temperature range adaptability and while maintaining the core advantages of Platinum cured mold silicone Key highlights are as follows:

1.Ultrawide temperature range tolerance It can be used at 300℃ for a long time without aging or deformation, and maintains good elasticity at 80℃, adapting to extreme working condition production

2.Thorough curing without residues, shrinkage rate ≤ 01% The mold has high dimensional precision and can accurately replicate 01mm fine textures, meeting highend prototyping needs

3.Compatibility with both foodgrade and industrialgrade standards Certified by FDA and RoHS, it is suitable for both hightemperature baking food molds and precision industrial accessory manufacturing

4.Strong antiaging and chemical corrosion resistance It can resist weak acids, weak alkalis, and most organic solvents, and the mold service life is extended by more than 50% compared to ordinary hightemperature resistant silicone

5.Flexible customization of fluidity and hardness, adjustable from soft (Shore 10A) to hard (Shore 60A) to adapt to different molding scenarios

6.Environmentally friendly and odorless, no toxic gas is released during curing It complies with global highend manufacturing environmental standards, ensuring the safety of the production environment

Relying on core formula R&D capabilities, the product can meet various hightemperature and highprecision molding needs, filling the application gap of ordinary silicone in highend industrial scenarios

How to Use

1.Pour Part A and Part B into a clean container at a weight ratio of 1:1, stir at high speed with an electric mixer for 3 minutes (rotational speed 200300r/min) to ensure uniform mixing

2.Vacuum defoaming for 35 minutes until no bubbles protrude on the material surface Extend the defoaming time appropriately if the viscosity is high

3.Slowly pour along the edge of the mold frame to avoid texture deformation caused by impacting the prototype For complex structures, pouring can be done in multiple times

4.Cure at room temperature for 56 hours, or heat cure at 100150℃ for 1530 minutes After hightemperature curing, it is recommended to cool naturally to room temperature before demolding

5.Trim the mold edges as needed after demolding, and it can be put into hightemperature working condition production
