Cured Polysulfide Sealant Removal

Two Component Polysulfide Sealant

Polysulfide Sealant is often used in aerospace applications, acting as an adhesive and a sealant for panels on airplanes. This caulking is designed to be difficult to remove, but if it is stuck to something you don’t want or you need to separate some of the panels, you need to remove the caulking. This is more difficult when the caulk has cured, because it’s harder to scrape. The fix is to use an emulsifier/stripping agent specifically made for polysulfide sealant removal.

Instructions

1 Locate the affected area. Apply the emulsifier/stripping agent to the surface right out of the container.
2 Scrape the Polysulfide Sealant off the surface. Work all of the seams to make sure all of the caulking is gone.
3 Look for signs of Polysulfide Sealant that didn’t dissolve or isn’t accessible. Reapply the emulsifier/stripping agent and let it sit for five to 10 minutes. Scrape off again.

Tips & Warnings

If you have to apply the emulsifier/stripping agent to a vertical surface, look for one that comes in paste form. You can brush it onto the surface with a paintbrush.

polysulfide sealant Introduction

Gather polysulfide sealant is sulfur sealant with liquid thiokol as the main materials, cooperate with viscous resin, curing agent, promoting agents, such as reinforcing agent made of sealant. Such sealant has excellent resistance to fuel, hydraulic oil, water and all kinds of chemical performance and heat resistance and atmospheric aging performance. General for sulfide type. According to the components can be divided into two components (or three components) and single component type. Its processing premixed-the grinding process method-filling. Sulfur is widely used for sealing glue together civil building, automobile manufacturing industries as embedded sewing, sealing material, also often used in the various types of oil tank, fuel tanks, aviation machinery, composite glass sealing.

Application

1, used for external welding line of car chassis, waterproof rust protection.
2, used for ceiling compartments body, the floor, metal, wood, plastics, foam material such as adhesive and seal of the joints.
3, used for ceiling compartments, the floor of the body, the metal plates screws, rivets waterproof and anti-rust seal, etc.

Note

1, can’t and silicon rubber sealing the reasonability of mixing with use, otherwise, it will affect its bond properties.
2, 5 ℃ above in construction temperature, otherwise, it will affect its bonding and curing speed.
3, before construction do small kind test.

Storage conditions: away from fire, avoid ventilation, temperature in 5 ℃ ~ 30 ℃.
