## Overview

Hylomar Advanced Formulation is a 3 oz. solvent-free, non-setting polyester-urethane jointing compound designed for easy application and reusability. It offers exceptional resistance to automotive fluids and vibration, supports unlimited assembly time, and operates reliably across a broad temperature range (-58°F to 482°F). Ideal for gasket dressing and metal flange sealing, it ensures leak-proof performance while enabling hassle-free disassembly and gasket reuse.

## Description

Hylomar ADVANCED FORMULATION is a non setting non hardening polyester-urethane based jointing compound. Since it is non setting, it can be taken apart and put back together without re-application as long as it remains clean. It offers an unlimited assembly time, is resistant to almost all fluids and vibration. Hylomar AF is easy to apply, and easy to disassemble. It will also clean off easily with acetone or Hyloclean. Hylomar AF is solvent free and does not have the gap filling properties of Hylomar Universal Blue or Hylomar M. Advanced formulation is ideally suited for dressing gaskets to assist with gasket alignment during assembly, for easy removal later, and to improve the sealing properties of all types of gaskets. Gaskets dressed with Hylomar AF can usually be reused as they will not stick to the base metal. Hylomar AF makes future disassembly of parts very easy since it is non setting. Hylomar AF is designed to seal close fitting metal flanges and is resistant to most automotive fluids and chemicals. Temperature range -58°F to +482°F continuous.

Review: Execellent gasket prep and sealant. Easy use. - A reworkable sealant and gasket prep material. Seals against fuels and oils. This is quite tacky and greatly helps in assembly of gasketed parts. Easy application as it is initially quite spreadable, then quite tacky.
Review: This is equivilent to the Hylomar once sold by a top American maker of sealants - When my tube of Hylomar emptied I found that the American sealant company (whose name was on the tube), no longer sells this great stuff. Hylomar is an excellent gasket dressing that seals but allows easy disassembly and the re-use of gaskets in many cases. It is also good for metal to metal close fitting machined joints such as case halves. The silver seal Advanced Formulation (solvent free) never sets or skins over and it is reasonably priced. Great Stuff!

## Questions & Answers

**Q: Will the Hylomar AF be resistant to brake fluid?**
A: “resistant to brake fluid” .. if you’re considering the use of Hylomar AF as a sealer for brake lines or unions, I’d use a hydraulic/pneumatic sealer. If you’re using AF on plastic brake components, I’d consider a silicone sealant before this; or, see below. Since AF is removed with alcohol and never cures in the traditional sense, and brake fluid is glycol-based, this to me would present a problem. The manufacturer does say resistant to “automotive fluids” but does not specifically say brake fluid.

 Hylomar Blue might be a better choice if you’re dealing with brake fluid; no guarantee, even though Blue requires a different solvent, acetone, for removal. Remember, these are gasketing compounds, or used on tight fitting flanges. Blue can also be used in sealing plastic to plastic components. Without a specific procedure / application, that’s the best I can do.

**Q: What is the difference between AF and Blue?**
A: Universal Blue was the original formula and had more solvent as compared to AF. You have to let Blue sit for a few minutes to allow the solvents to evaporate before putting the pieces together. Not so with the Universal. I've tried both products and I much prefer the AF formula over the Universal Blue.
