MG Chemicals 1035-85mL is a one-component, non-corrosive, translucent electronics-grade RTV silicone sealant that cures to a tough, resilient rubber on exposure to atmospheric moisture at room temperature. Unlike acetoxy-cure silicones (which release acetic acid and can corrode copper), the 1035 uses a neutral-cure system — releasing a neutral vapor that is safe for copper, sensitive metals, and electronic assemblies. It is specifically formulated for sealing and bonding electronic components on PCBs, protecting copper connections, and weatherproofing electrical assemblies. This listing is for a case of 6 x 85ml tubes.

Key Features
- Non-corrosive neutral cure — electronics-safe — releases neutral vapor instead of acetic acid; safe for copper traces, sensitive metals, and electronic components; the critical advantage over acetoxy-cure silicones (RTV102, RTV103, RTV106) for direct PCB use
- UL 94HB recognized — File No. E36952; meets UL flammability requirements for electronics applications
- Fast initial adhesion build — allows movement of sealed assemblies sooner than slower-cure silicones; increases production throughput
- Primerless adhesion — bonds to most metals and plastics without primer
- Wide temperature range — -60°C to +204°C continuous; peaks to +260°C short-term
- Excellent electrical insulation — suitable for PCB component sealing, connector protection, and environmental protection of electronic assemblies
- UV, chemical, and weather resistance — suitable for outdoor and industrial environments
Frequently Asked Questions
What makes 1035 different from RTV102, RTV103, and RTV106?
The key difference is cure chemistry. RTV102, RTV103, and RTV106 all use acetoxy cure, which releases acetic acid (vinegar odor) during curing — corrosive to copper and sensitive metals. The 1035 uses a neutral cure system that releases a non-corrosive neutral vapor, making it safe for direct use on PCBs, copper traces, and sensitive electronic assemblies without risk of corrosion. If your application involves bare copper, populated PCBs, or copper-alloy connectors, the 1035 is the correct choice over any acetoxy-cure RTV.
Is 1035-85mL in stock?
RTV products including 1035-85mL are not stocked items. Please call MTE Solutions at 651-600-3838 for current pricing and lead times before ordering. This listing is for a case of 6 x 85ml tubes.
What is the UL 94HB rating?
UL 94HB is the basic UL flammability classification for plastics and elastomers, indicating the material passes horizontal burn testing. It confirms the cured silicone meets minimum UL flammability requirements for electronics applications. File No. E36952 is the specific UL recognition file for MG Chemicals 1035.
Can 1035 be used to weatherproof motor and power cord entry points?
Yes — 1035 is specifically noted as an excellent sealant for weatherproofing wherever power cords enter motors. Its neutral cure, flexible rubber cure, and good confined-cure properties make it well-suited for sealing around cable entries, grommets, and penetrations in motor housings and electrical enclosures.
What is the maximum application section depth?
Because 1035 uses a moisture cure system, it should not be applied in sections greater than 6mm (1/4 in.) thick. Moisture must penetrate from the surface to cure the full depth. For deeper sections, use a Momentive one-component addition cure or two-component silicone compound instead.
