For Buyers Making Concrete Molds — Not Buying Finished Molds
We supply liquid RTV-2 silicone rubber for customers who use silicone to make concrete molds, not ready-made concrete mold products.
If your project involves stone texture, decorative concrete, GFRC, form liners, countertops or repetitive casting, we can help screen a more suitable silicone grade before sampling.
Built for Real Concrete Mold Making Applications
01
Stone Texture & Decorative Concrete Panels
For projects where surface clarity directly affects the visual value of the finished concrete part.
Why buyers care: clean texture transfer and more practical mold life.
02
GFRC/GRC Form Liners & Architectural Elements
For façade panels, trims, shaped sections, and decorative architectural components.
Why buyers care: larger molds need better stability and more controlled demolding.
03
Concrete Countertops, Sinks & Custom Surfaces
For edges, basins, negative forms, and custom shapes.
Why buyers care: release quality and edge detail affect finishing time and final appearance.
04
Repeat Casting, Form Liners & Concrete Stamps
For projects where consistency matters from trial runs to repeated production.
Why buyers care: buyers want a grade that supports more predictable repeat use.
How to Choose the Right Silicone for Concrete Molds？
For concrete mold making, the right silicone grade is not only about Shore A hardness.
It also depends on:
- 01. mold size
- 02. surface texture depth
- 03. part geometry
- 04. demolding stress
- 05. repeat casting requirement
- 06. abrasion from the concrete system
| Project Type | Suggested Shore A | Why Buyers Choose It |
|---|---|---|
| Fine texture/lighter castings | 20–25 | easier detail capture and practical flexibility |
| General decorative concrete molds | 25–30 | balanced durability and release performance |
| Larger molds/deeper texture/heavier stress | 30–40 | better structural support and longer service life potential |
Why Concrete Mold Buyers Work with Us？
15+ Years in Liquid RTV-2 Silicone Manufacturing
We focus on liquid RTV-2 silicone production and understand that concrete mold projects require more than generic mold-making claims.
Application-Based Grade Recommendation
We do not recommend a grade based only on hardness. We look at mold size, texture complexity, demolding stress, and repeat-use expectations.
Better Fit for Decorative & Architectural Concrete Work
Suitable for customers making stone texture molds, GFRC liners, countertops, custom surfaces and other concrete casting molds where detail and release both matter.
From Trial Evaluation to Bulk Supply
We support sample testing, technical discussion, and bulk supply planning for customers moving from development to repeat production.
Technical documents and suitable grade suggestions can be shared based on your mold type and project requirements.
A Practical Note for Concrete Mold Performance
Concrete mix design affects both demolding behavior and practical mold life. Projects with sharper edges, deeper texture or more abrasive concrete systems can place more stress on the mold surface. That is why grade selection and release practice both matter when repeat casting consistency is important.
If needed, we can discuss your mold structure, casting type and release approach before recommending a trial grade.
What Serious Buyers Usually Want to Confirm Before Sampling
Before moving into sample testing, buyers usually want to confirm a few practical points first.
DETAIL TRANSFER
Will the silicone capture fine surface detail clearly?
Important for stone, decorative and texture-based molds.
DEMOLDING
Will demolding be manageable in repeated use?
Important for molds with deeper patterns, edges or heavier handling stress.
GRADE FIT
Can the supplier recommend a more suitable grade before testing?
Important when buyers want to reduce trial-and-error and move faster toward a usable sample.
SUPPLY
Can supply continue if the project moves into repeat orders?
Important for customers who plan to move from sample testing to regular procurement.
Factory Capacity
Built for Stable Supply — Not Just a Sample Order
For concrete mold buyers, product fit is only part of the decision.
Supply stability, production consistency, and technical communication also matter when a project moves from testing to repeat casting.
We support customers with:
- manufacturing capability
- internal quality control
- application-focused communication
- sample-to-bulk supply support
You ask, we answer
Questions Buyers Usually Ask Before Ordering
Softer grades are often easier for detailed textures and more complex demolding. Higher Shore A grades are usually considered for larger molds, deeper textures, or heavier demolding stress.
That depends on the master pattern, mold size, and surface shape. Pour-on systems are often used for simpler setups, while brush-on systems can be more suitable for vertical or more complex surfaces.
It can, but practical mold life depends on the concrete system, mold design, texture depth, release practice and demolding conditions.
That is why correct grade selection matters early.
In many repeat-casting situations, good release practice can help protect mold detail and support cleaner demolding, especially in more abrasive systems.
