MG Chemicals RTV108-300mL Clear Silicone Sealant, 300ml Cartridge
MG Chemicals RTV108-300mL Clear Silicone Sealant, 300ml Cartridge
MG Chemicals RTV108 is a one-part, clear RTV silicone adhesive sealant supplied in a 300 mL cartridge. It cures with atmospheric moisture at room temperature to form a flexible seal. The cartridge suits repeated dispensing for sealing, gasketing and bonding jobs where this acetoxy-cure formulation is appropriate.
Sold individually as one 300 mL cartridge.
Best uses
- Sealing and gasketing on compatible glass, ceramic and metal surfaces.
- Production or maintenance jobs that call for a larger cartridge rather than a small squeeze tube.
- Flexible bonding and sealing where the application can tolerate acetic acid released during cure.
Material compatibility: This sealant releases acetic acid as it cures. Check the manufacturer's technical data and test compatibility before applying it to sensitive electronics, metals or plastics; do not assume universal PCB or component compatibility.

Frequently asked questions
What does RTV mean? Room-temperature vulcanizing: the sealant cures without a heat-curing step by reacting with moisture in the air.
Does RTV108 release anything while curing? Yes. The existing product information identifies acetic acid as a cure by-product; provide suitable ventilation and check substrate compatibility.
How should surfaces be prepared? Start with clean, dry surfaces free of oil or other contamination, then follow the manufacturer's application guidance.
Can it be used on any electronics assembly? Not without checking compatibility. The acetic-acid cure system may be unsuitable around sensitive components or substrates; consult the product technical data for your application.
Why choose the 300 mL cartridge? It provides a larger dispensing format than the 85 mL tube for repeat or higher-volume sealing jobs.
