Product Sections
BBDINO Silicone Mold Making Kit
The BBDINO kit is a 1:1 by volume silicone system designed for mold making with resin, jewelry, candles, concrete, and plaster. It features low viscosity for thorough mixing and a self-degas function, reducing air bubbles without a vacuum chamber. With a working time around 30 minutes and a cure time near 5 hours, it supports relatively quick turnaround for multiple molds in a single project session. These traits make it suitable for larger molds or batches that require precision without lengthy waiting periods.
Key considerations include the 1:1 mix ratio by volume or weight and the practical working window, which balances detail capture with user convenience. The kit’s high strength silicone helps maintain mold integrity through several reuse cycles, though user success will depend on mold geometry and resin viscosity. If you’re experimenting with translucent pigments or mica powders, this system can pair well with color additives to expand design possibilities.
LET’S RESIN Silicone Mold Making Kit 72oz
This LET’S RESIN kit uses premium platinum-cured silicone, offering a clear, flexible, and non-toxic formulation ideal for resin molds. The 72-ounce kit aims at hobbyists and small studios seeking high-quality, durable results with reliable demolding. The platinum cure provides superior fidelity and resistance to wear across multiple uses. Uniform mixing and low odor make it friendly for home studios. For colorists, the translucency allows visual checks during pouring and curing, enhancing mold accuracy and tracking resin flow through complex interiors.
Considerations include safety for skin contact, long-term durability, and the ability to replicate fine details. The kit’s self-defoaming characteristics help achieve smooth surfaces without extensive degassing. This option suits crafters planning slightly larger molds or repeated runs, while maintaining an approachable price point for enthusiasts building a resin casting workflow.
LET’S RESIN Silicone Mold Making Kit 63.48oz
This 63.48-ounce LET’S RESIN kit emphasizes a 1:1 by weight mix ratio, delivering a clear and flexible silicone suitable for general resin molds. The kit is designed for straightforward mixing and pouring, with a working time that supports detailed mold creation without rushing. The complete cure time is longer than some fast-set formulas, but the durability and ease of demolding make it well-suited for more intricate designs or larger mold cavities. Color additives can be used to create bespoke, vibrant molds that showcase resin coloration effectively.
LET’S RESIN Silicone Putty
The LET’S RESIN silicone putty is a fast, hand-mixed option ideal for making simple, reusable molds. With a 1:1 ratio and a working time of about five minutes, it suits quick prototyping or small-batch resin projects. The putty’s non-toxic, low-odor formulation supports safe use in home studios. It’s particularly useful for beginners who want to experiment with mold shapes without investing in a larger kit. The material’s temperature tolerance and flexibility support a range of resin casting applications, including soap and wax molds alongside resin.
ISSEVE Silicone Jars Molds with Lids
The ISSEVE jars molds offer a practical alternative for resin projects that require storage or display containers. While not a traditional “mold kit” for casting large resin pieces, these silicone jars molds provide reliable silicone quality for jar-shaped castings with lids. They are well-suited for small storage solutions, gift containers, or decorative resin jars. The silicone’s flexibility supports easy demolding, while the included lids help with containment during curing. This option broadens use cases beyond typical jewelry or sculpture molds, appealing to organizers and display creators alike.
Buying Guide
- Mix Ratio and Handling: Most resin-friendly silicone kits use a 1:1 by volume or weight ratio. Confirm whether the kit requires precise digital scales or if approximate measuring suffices for your projects. Consistency in ratio directly affects cure and mold fidelity.
- Cure Time and Working Time: Longer working times allow more complex designs, while faster cures speed up production. Consider your project size and scheduling when selecting a kit. Self-degas features help reduce bubbles without a vacuum chamber.
- Material Type: Platinum-cured silicone tends to offer better durability, lower odor, and higher fidelity for fine details, especially in resin molds. Look for low-odor formulations if you’re working in a small studio or home environment.
- Viscosity and Flow: Low-viscosity silicones flow easily into mold details, capturing fine textures. However, extremely low viscosities may require careful pouring to avoid air entrapment in larger molds.
- Color and Clarity: Translucent or clear silicone helps visual inspection during pouring and curing. Color changes can be added with mica powders or pigments if compatible with the kit.
- Reusability and Durability: Durable silicone resists tearing and maintains flexibility after multiple demolding cycles. Check manufacturer guidance on maximum reuse counts, affected by mold size and resin type.
- Safety and Cleanup: Look for skin-safe formulations and easy cleanup with soap and water. Non-toxic and odor-controlled options are preferable for long sessions.
- Accessories and Support: Some kits include A and B parts with clear mixing instructions, plus tips for avoiding bubbles. Consider kits that provide troubleshooting guidance or color-matching options with mica powders.
- Size and Scope: Choose a kit that aligns with your typical mold dimensions. Larger kits may offer more volume for multi-mold sessions, while smaller kits are ideal for beginners testing resin casting.
- Price vs. Value: Compare working times, cure times, and included volumes to determine value. Durability and ease of use often justify a higher initial investment if you plan frequent use.
In summary, the best resin-friendly silicone choices balance ease of use, fidelity, and safety. For beginners, a 1:1 by weight or volume kit with a reasonable working time and clear instructions is ideal. For hobbyists expanding into complex or larger molds, a platinum-cured, low-odor system with high demolding elasticity offers long-term value. Consider adding a silicone putty for quick prototypes, while jars molds provide practical storage and display options that complement resin projects.
