What Are the Different Permatex Types?
Permatex is a leading manufacturer of adhesives, sealants, and lubricants for the automotive industry, heavy equipment, and marine industries. They offer various types of products that are used in many different applications.
1. Strips Permatex
Strips Permatex are used to repair fluid leaks on an engine or transmission. The strips are made from two materials that are heat activated so they can be placed under pressure and applied to the leaky area. When the strips cool down, they will stay in place without further adhesive application or curing time.
2. Paste Permatex
Paste Permatex is a two-part adhesive that is used to fix leaking gaskets on oil pans, valve covers, and other areas where gaskets may wear out over time due to age or exposure to extreme heat.
The paste is applied directly onto the damaged area, where it will cure within 5 minutes after application. No curing time is required for this application since it is already pre-mixed before application.
3. Liquid Permatex
Liquid Permatex is an industrial-grade adhesive that can be used for many applications, such as bonding plastic parts together during installation or repairing them after installation. It has been tested by numerous organizations and is approved for use with many different parts, including automobile parts, kitchen utensils, and automotive parts.

They also do not contain silicone, making them safe for indoor use around children and pets. These features make them ideal for use around the house or in automotive repair shops where toxic fumes may be an issue.
3. Good compatibility
Permatex adhesives have excellent bonding qualities with many materials, including wood, metal, fabric, and rubber. They also bond well to most plastics except polyethylene and polypropylene. This makes them ideal for use on a wide range of surfaces and materials, from metal to fabric to wood.

The Permatex adhesives are compatible with most types of other adhesives, such as super glue, epoxy, polyvinyl acetate, and contact cement. This trait makes them useful for repairing multiple surfaces around the home or automotive shop.
Permatex 2 Vs 3
Permatex Form A Gasket 1 is a sealant that creates a tight bond between two surfaces. It is available in two varieties: Form A and Form B.
Permatex Form A Gasket 2 is one of the two types of form-a-gasket sealants produced by Permatex. This type of sealant can work on both rigid and non-rigid materials, while Permatex Form A Gasket 1 can only be used on rigid materials.
Permatex Form A Gasket 1 has many uses in aviation applications due to its ability to withstand high pressure and extreme temperature ranges, making it ideal for use on aircraft engines and fuselages.
It also works well with close-fitting machined surfaces because it can fill gaps up to .005 inches wide without leaving voids behind.
In contrast to Permatex 3, which is ideal for use in aviation applications and close-fitting machined surfaces, Permatex 2 is excellent for adhering to non-rigid materials. It may not survive as long as Permatex Form A Gasket 2 due to its lower durability.
Permatex forms a gasket 2 is preferable to Permatex form a gasket 1 if you need to utilize it on non-rigid materials.
What Is The Difference Between Permatex 2 And 3 Sealant: Table
