Nicpro 170oz Silicone Mold Making Kit - Complete 1:1 Silicone Set

In this review of the Nicpro 170oz Silicone Mold Making Kit the bottom line is simple: this kit is aimed at hobbyists and small-studio makers who want a ready-to-use, food- and skin-safe platinum silicone solution with plenty of accessories to start casting. The most compelling reason to buy is the complete bundle combined with a low-viscosity, flexible RTV-2 silicone that reproduces detail well and cures at room temperature in a few hours. The review highlights performance, ease of use and realistic limits based on user feedback.

Key Features

• Complete kit: The bundle includes 170oz of liquid silicone, two adjustable mold housings, stirring sticks, measuring cups, gloves, tablecloths and a user manual so beginners have nearly everything they need to start.
• Food and skin contact safe: Platinum-grade RTV-2 silicone is specified as non-toxic and odorless, making it suitable for soap, candle, chocolate or other applications where safe contact is important.
• Easy mixing and pouring: The 1:1 mix ratio and low viscosity make the silicone easy to measure and pour, helping capture fine detail for 1-piece and 2-piece 3D molds.
• Fast room-temperature cure: Typical cure is 3-5 hours at 73.4F (23C) with a 30 minute workable time, so projects can move from pour to demold in a single session depending on thickness.
• Durable, flexible molds: Rated around Shore 20A for tear resistance, cured molds are flexible yet firm and are described as long lasting when cared for.

Who It's For

This kit is best for makers who create medium-sized projects such as decorative resin pieces, one-piece or two-piece 3D silicone molds, flat molds and craft goods like candles, soap and low-temperature edible items. Beginners will appreciate the measuring cups, sticks and housings that reduce the need to source extra supplies.

It may be less suitable for professional moldmakers who require very large molds, strict industrial specifications or vacuum degassing for complex undercuts. Also, this silicone is not compatible with UV resin curing and may show variable cure behavior under atypical temperatures.

Pros & Cons
