Nicpro 140 oz Silicone Mold Making Kit 1:1 Mix - Food Safe, Fast Cure

In this review the Nicpro 140 oz Silicone Mold Making Kit is judged as a solid, beginner-friendly option for makers who need a foodsafe, easy to mix silicone for onepiece and simple 3D molds. The kit stands out because it includes two 70 oz bottles that mix 1A:1B by weight and cure quickly at room temperature, making it a practical pick for craft projects where speed and safe contact with food or skin matter. It is particularly useful when users want low viscosity, good detail reproduction and middle flexibility without complex measuring.

Key Features

• 1:1 Mix Ratio: The two 70 oz bottles mix 1A:1B by weight for straightforward measuring and consistent batches when mixed thoroughly for at least 5 minutes.
• Food and Skin Safe: Platinum RTV-2 formula is non-toxic and odorless, suitable for molds used with candy, chocolate, cake or soap where food or skin contact is required.
• Fast Room-Temperature Cure: Typical cure is 3 to 5 hours at 73.4F / 23C with about 30 minutes of workable time, so projects move from mold making to casting quickly.
• Balanced Softness and Strength: Around 20A hardness provides middle tear resistance and flexibility, good for flat one-piece molds and 2piece 3D molds that need moderate durability.
• Beginner Kit Contents: The kit includes gloves, wooden sticks, graduated cups and tablecloths so a novice can mix and pour without sourcing extra supplies.

Who It's For

The Nicpro kit is best for hobbyists and small studio makers who cast resins, wax, concrete, soap, candle or edible items and need a foodsafe silicone that is easy to mix and quick to cure. It suits beginners because of the included accessories and simple 1:1 weight ratio.

Professional moldmakers working on hightemperature, industrial applications or who require very high tear strength or shore hardness should look elsewhere; the product is optimized for craft and culinary casting rather than heavy industrial use.

Pros & Cons

Pros

• Easy 1:1 mixing and low viscosity makes pouring and bubble reduction straightforward for clean detail.
• Food and skin contact safe platinum formula expands use to edible molds and personal projects.
• Fast cure time gets molds ready in a few hours, helping speed up small batch workflows.
• Starter kit extras mean fewer trips to buy tools and measuring supplies.

Cons

• Middle tear resistance may not satisfy heavy production runs or very demanding demolding situations.
• Cannot be used to cure with UV resin, so it is incompatible with that specific casting chemistry.
