Customized RTV2 liquid silicone formula: meeting the production needs of special stone products

Standard silicone sealant doesn't meet all production needs? We develop custom RTV2 silicone sealant formulations for cultured stone and wall tile factories, including curing speed, hardness, color, and special additives.

Every cultured stone and wall tile factory has unique production requirements, and commercially available standard RTV2 liquid silicone sealant may not perfectly match your casting materials, production rhythm, or product design. Custom silicone sealant formulations can address these specific issues.

• Faster Curing: For factories requiring rapid mold turnaround, we can reduce demolding time to 1–2 hours through an accelerated catalytic system.
• Slower Curing: For large molds requiring longer casting times, we can extend the working time to 60–90 minutes.
• Specific Hardness: Customizable hardness within the Shore A range of 10–50 to match product geometry and demolding requirements.
• Color Options: Available in colored silicone sealants such as red, blue, and green for easy mold identification or brand consistency.
• Special Additives: UV stabilizers for outdoor storage, antistatic agents for dust protection, food contact grade formulations, etc.

1. Requirements Communication: Our engineers understand your production processes, casting materials, and pain points.
2. Sample Development: We create 1–2kg lab samples for your testing.
3. Production Validation: You test the samples under actual production conditions and provide feedback.
4. Mass Production: After confirmation, we scale up production to ensure consistent quality.

Custom formulation MOQ is flexible, with a development cycle of 3-5 days. This service is especially valuable for factories with proprietary production processes or unique product lines.
