Cleanroom Sealant & Jointing Systems
The CleanSpace Sealant system provides the essential environmental barrier required to maintain airtight integrity across your modular cleanroom. Featuring specialized cold-weld technology for uPVC-to-uPVC bonding and food-grade silicone for dissimilar material interfaces, our sealants create smooth, non-porous transitions that prevent air leakage and microbial growth.
Designed to accommodate the natural movement of modular assemblies while resisting aggressive decontamination cycles, these systems ensure a monolithic finish across wall-to-floor, wall-to-ceiling, and component-to-panel junctions.
Advanced Jointing & Sealing Solutions
Our sealing suite is categorized by material compatibility and performance requirements:
Cold-Weld Technology
A chemical bonding process specifically for uPVC-faced Apex™ panels creates a fused, seamless joint that is more durable and cleanable than traditional caulking.
Hygienic Silicone Sealant
A premium RTV-732 based, food-grade silicone (FDA 177.2600) seals interfaces between dissimilar materials such as aluminum, steel, and glass.
Flexible Movement Accommodation
Maintains seal integrity under repeated cleaning cycles and minor structural shifts without cracking or debonding.
Broad Chemical Resistance
Withstands constant exposure to sterilized cleaning agents, including Spor-Klenz, VHP, and common biocides.
Multi-Color Availability
Available in white, black, aluminum, and clear finishes to provide a consistent aesthetic across all cleanroom architectural components.
Specialized Industry Applications
CleanSpace sealants are the standard for facilities requiring validated environmental separation:
Pharmaceutical & cGMP Facilities
Create seamless, fused joints in Grade A/B zones to eliminate potential particle traps.
Food & Beverage Production
Use FDA-compliant, food-safe silicone for washdown-heavy environments.
Biotechnology & Life Sciences
Ensure airtight seals for pressure-controlled laboratories and containment suites.
Microelectronics
Low-outgassing formulations maintain air purity standards in sensitive fabrication areas.
Frequently Asked Questions
Cold-Weld is used specifically to fuse uPVC finishes together, resulting in a monolithic, "melted" joint. Silicone is used for transitions between different materials—such as where a panel meets a floor track, a window frame, or a ceiling grid.
Yes. Both our Cold-Weld and RTV Silicone systems are tested for compatibility with aggressive pharmaceutical decontamination protocols and will not degrade or discolor when exposed to VHP.
Our RTV Silicone has a fast open time of approximately 45–60 seconds for rapid application, with a functional bond strength achieved in 8–10 minutes and a full cure typically occurring within 24 hours.
Absolutely. Our CleanSpace Silicone complies with FDA 177.2600 and MIL-A-46106, making it suitable for pharmaceutical, medical device, and food-grade environments.
