LET’S RESIN Silicone Mold Making Kit-Translucent
Premium molds making silicone material with platinum-cured chemistry offers a safe, non-toxic, low-odor formulation. The kit is translucent for visibility during mixing and curing. It is soft, flexible, and compatible with mica powder to add color. The 1:1 by weight mix ratio simplifies preparation, and a 5-minute working time allows for careful pouring. Bubbles naturally dissipate within about 2 hours, reducing the need for vacuum degassing. Cure time varies with mold size, typically around 4 hours or more.
LET’S RESIN 8oz Silicone Mold Making Trial Kit
This all-in-one starter kit includes 8oz of silicone rubber, sticks, measuring cups, and gloves. It cures at room temperature and can accelerate with gentle heating. Working time is 30–40 minutes, with full cure in 3–6 hours under typical conditions. The material is platinum-cured, non-toxic, and low-odor with minimal shrinkage, offering high tear resistance and long mold life for resin or silicone molds.
BBDINO Silicone Mold Making Kit, 30A Sapphire Blue
Includes liquid silicone with a 1:1 mix ratio by volume or weight, enabling flexible, durable molds. It features self-degassing because of its low viscosity, eliminating the need for a vacuum chamber. The kit provides at least 30 minutes of working time and typically cures in about 5 hours, depending on conditions. Ideal for resin, jewelry, candles, and more, the silicone blends well with many casting materials.
LET’S RESIN Silicone Mold Making Kit 140oz
Large-capacity silicone mold kit with a 1:1 mix ratio, designed for extended projects. platinum-cured silicone is non-toxic and odor-free, with minimal shrinkage for precise reproductions. The kit supports mica powder color mixing and produces bubbles that disappear within about 2 hours without vacuum degassing. Cure time ranges from several hours to half a day, depending on the mold dimensions and thickness.
MITINU Silicone Mold Making Kit, 38.8oz
The 38.8-ounce kit includes platinum-cure silicone with a hardness of 15A for high elasticity and detail replication. The 1:1 mix ratio keeps preparation straightforward. Working time is around 40 minutes, with curing in 2–4 hours at room temperature. The material accommodates both 3D silicone molds and flat resin molds, making demolding easier due to its flexible nature.
CHANGTIKEJI Silicone Mold Making Kit, 64oz
This 64-ounce kit provides two bottles totaling 64 ounces of platinum-cure silicone, plus mixing sticks and disposable gloves. It features a low-viscosity formula and 10A hardness for flexibility and accurate detail reproduction. The kit emphasizes a bubble-free process without vacuum degassing, simplifying the workflow for beginners and seasoned mold makers alike.
Buying Guide
- Mix ratio and packaging: Most kits use a 1:1 ratio by weight or volume. Choose a kit that matches your preferred measuring method and includes mixing tools.
- Working time and cure time: If you are new to molding, look for longer working times (30–40 minutes or more) and cure windows in the 3–12 hour range, depending on project size.
- Viscosity and bubble management: Low-viscosity formulas reduce air entrapment. Some kits claim self-degassing or bubble dissipation within 1–2 hours without vacuum equipment.
- Material safety: Platinum-cured silicone is widely considered safe for crafts and food-safe applications after proper curing. Confirm odor and non-toxicity for your workspace.
- Hardness and flexibility: Silicone hardness (measured in Shore A) affects demolding and detail. Softer 10–15A rubbers excel with fine details but may deform under heavy use; firmer options like 30A–40A hold shape better for rigid casts.
- Color and additives: Some kits allow mica powder color mixing. If you plan to color molds, ensure the base silicone accepts pigments without affecting cure.
- Volume and project scope: Large-volume kits are cost-effective for multiple projects, but ensure you have storage space and proper curing conditions.
- Application versatility: Consider whether you need molds for resin, candles, soap, chocolate, or concrete to pick a kit with broad compatibility.
To maximize results, follow each kit’s specific instructions for mixing, degassing (if required), pouring, and curing. Store silicone in a cool, dry place away from direct sunlight to preserve elasticity and prevent premature curing.
