Authentic User Feedback

🎨 Sculptor & Artist Reviews

⭐⭐⭐⭐⭐ Elena Martinez - Bronze Sculptor, Art Studio Owner
"I’ve been using the OTTSilicone RTV-2 Advanced Model for six months now, and it’s transformed my workflow. The high flow and low viscosity make pouring into intricate wax models effortless, and I haven’t had a single air bubble issue since switching. It holds up perfectly during bronze pours at 300°C—no warping or degradation. I’m getting at least 15 uses per mold thanks to its aging resistance. This is the best silicone I’ve used in over a decade of casting."

🔧 Industrial Foundry Technician Reviews

⭐⭐⭐⭐⭐ James Carter - Foundry Operations Manager
"We switched to OTTSilicone’s Pro Model for our automotive component molds, and the difference is night and day. The flame retardant UL94 V-0 certification gives us peace of mind in our high-heat environment, and the 40 kN/m tear strength means molds last nearly twice as long as before. The 100:3 mixing ratio is consistent across batches, which has reduced waste and rework. For industrial-scale casting, this is now our standard."

🏺 Hobbyist & Home Studio Reviews

⭐⭐⭐⭐☆ Daniel Park - Amateur Sculptor
"As a weekend artist working from my garage, I needed something reliable but easy to use. The Base Model RTV-2 is perfect—simple mixing, great detail replication, and it survived my first bronze pour without cracking. I was nervous about handling high temps, but it held up to 280°C with no issues. Only reason I didn’t give five stars is the packaging—1L bottles are great, but I wish they offered a smaller trial size for beginners."

🏭 Manufacturing Engineer Reviews

⭐⭐⭐⭐⭐ Lena Fischer - Industrial Molding Engineer, Germany
"We evaluated three silicone brands for aerospace-grade component molds. OTTSilicone’s Advanced Grade outperformed all others in UV resistance (2000h) and rigidity under thermal cycling. The Shore A50 hardness maintains mold geometry even after repeated use, and we’ve seen zero shrinkage in precision parts. Their technical team also helped us customize a 98:3 mixing ratio for a specific viscosity need—outstanding support."

🖌️ Art Conservator & Restoration Specialist

⭐⭐⭐⭐⭐ Marcus Reed - Museum Restoration Lead
"We use RTV-2 for replicating historical bronze elements in restoration projects. The 500+ hour UV resistance ensures our molds don’t degrade during long-term outdoor exposure during site work. The high sliding property allows clean demolding without damaging fragile original surfaces. We’ve tested it against several high-end brands, and OTTSilicone delivers superior detail retention and longevity. Now standard in our conservation toolkit."
