Is Permatex Surface Prep necessary?

Premium Member. The Technical Data Sheet for Permatex Anaerobic #51813 makes no mention of the need for the surface prep activator except in cases where cure time is a critical factor. Where cure speed is unacceptably long, or large gaps are present, applying activator to the surface will improve cure speed.

Can I use RTV instead of a gasket?

It is fine to use the correct RTV sealant instead of a gasket if used in the right application (oil, high temp, fuel). Not, however, if the gasket thickness is required to produce a specific amount of clearance. RTV sealant is better than primitive gaskets in most applications ie.

What is anaerobic gasket maker used for?

Permatex Anaerobic Gasket Maker is designed primarily for use on aluminum, iron, and steel flanged mating surfaces. This non-corrosive gasketing material is ideal for on-the-spot and emergency repairs, or when a conventional gasket is unavailable.

Is silicone sealant anaerobic?

Aerobic sealants are often identified as RTV silicone rubber compounds, under names such as GM, GE, Permatex® , Devcon® , Dow Corning, MOPAR® , FelPro® , Loctite® , or Versa Chem® . Anaerobic sealants are those that cure in the absence of air.

What does anaerobic mean?

without air’Aerobic’ and ‘anaerobic’ are terms used to describe how cells within the body produce energy and refer to energy systems. … Anaerobic means ‘without air’ and refers to the body producing energy without oxygen.

What is an anaerobic sealer?

Anaerobic sealants, such as flange and thread sealants, strengthen joints and seals in systems with mechanically locked structures. They create seals through the hardening of resins and chemical compounds, but only in the absence of air. As long as anaerobic sealants are exposed to air, they will not harden or cure.

What is needed for an anaerobic sealer to cure?

Full cure of anaerobic adhesives may be achieved more rapidly using short-term exposure to heat (e.g. 30 minutes at 120 degrees Celsius). In assemblies where a liquid primer or activator is required to accelerate cure, the primer is applied to one or both fastener surfaces before the adhesive is applied.

How long to let RTV set before tightening?

When using RTV make sure to apply silicone in a thin bead and on the inside of the mounting holes. Snug the cover up and let it sit for 15 minutes to firm up and the torque it to spec. I usually tighten by hand and then give the RTV an hour to cure. After that fill and enjoy.

What is RTV sealant used for?

RTV silicone adhesive is a ready-to-use sealant that can resist weathering and chemicals, often used for electrical insulation. The adhesive is often applied to surfaces when pourable sealant cannot be used.

Do metal gaskets need sealant?

Metal/Plastic Carrier Gaskets Sealants: Dry. … Also, RTV can extrude out when the gasket is compressed, and it could end up in an oil or coolant passage and restrict or block flow. If a carrier-style gasket requires a sealant, some will include a portion in the kit.

Does RTV really need 24 hours?

However, most gasketing products require 24 hours of cure time. When using RTV gasketing, proper reassembly requires the following: Apply a continuous bead of silicone to the mating surface. Assemble parts with bolts finger tight ensuring contact is established while the silicone is still wet.
