There are many types of plastic and metal.It can be difficult to remove it once it has hardened.It starts in a liquid state.When it is mixed, the substance gets hotter until it starts to cool off.If you get it back to a liquid or gel-like state, you can remove it from the surface.If you take proper precautions and are patient, it can be done relatively easily.
Step 1: Gloves, goggles, and a respirator are required.
Vapors that can irritate your eyes, lungs, and mucus membranes can be produced by heat.If you want to protect yourself, put on safety goggles and a mask.You should wear rubber gloves with elastic bands that extend at least 3 inches past your wrist to protect your skin.The best type of respirator is dependent on what you make of it.The Material Safety Data Sheet (MSDS) can be used to find out what type of equipment you need.Make sure your goggles completely cover your eyes and sit against your skin with no openings to let in air.A built-in eye shield can be used with a PPE mask.The mask should be tested for proper fit and seal.If you have trouble getting a good seal, you may need to get a mask or trim facial hair.If you smell strong chemical odors while wearing your respirator, it may be time to replace it.You should leave the area immediately so that you can make any necessary adjustments to your respirator.
Step 2: There are clothes that cover your skin.
There is a pair of tight pants and a long-sleeved shirt.Make sure the buttons are secure if the shirt is a button-up.The purpose of this is to prevent your skin from reacting to the fumes that come from heating the epoxy.
Step 3: The surface should be soaked in acetone for at least one hour.
If the epoxy is attached to a wooden surface, soak the area in acetone for an hour or more before using heat.The object can either be placed in acetone or dripped onto the surface.The wood will absorb acetone.When dealing with epoxy on plastic, marble, cement, vinyl, or metal, any chemical will interact with the top of the surface, but they will not penetrate down into the layers like they do with wood.
Step 4: The heat gun can be used for several minutes.
The goal is to raise the temperature to over 200 F.Don't let the heat gun stay at the same position for too long.Keep an eye on the surface so you don't warm it up too much and burn it.You can use a soldering iron instead of using a heat gun.After the iron is heated, apply it to a specific area.The epoxy will be softened by this.You can place an object on a hot plate if you want to heat it up.This will do the same thing as the heat gun, and is more frequently available.
Step 5: It's best to heat small areas at a time.
If you heat the entire bond line at once, you won't be able to keep it hot for long.Work on segments that are less than 2 inches in length.Work on the segment next to the first after you have done one segment.It will be easier to get away with it now that the edge is open.
Step 6: Remove the heated epoxy with a plastic scraper.
The plastic scraper is strong enough to remove the epoxy from the surface.The heat did not penetrate all the way down into the layers.If this is the case, you should keep reheating the area and scraper until all the epoxy has been removed.After you have heated the area, don't heat it again.Wait a few minutes for the epoxy to cool off.You could cause the area to catch on fire.scrapers made of metal can cause damage to the surface you are working on.
Step 7: Gloves, goggles, and a mask with gas and vapors are required.
Refrigerants can cause irritation to your eyes, lungs, skin, and mucus membranes.A sealed respirator mask with gas and Vapor Cartridges and a pair of tight-fitting safety goggles are required.Put on a pair of rubber gloves that extend at least 3 inches past your wrists to protect your skin.Refer to the Material Safety Data Sheets for more information.Instructions on how to safety handle the materials and what kinds of protective equipment you need will be provided on these sheets.The 3M Cartridge and Filter Guide can be used to determine the correct color code for the type of respirator you need.Do you know if the refrigerant you plant is legal in your area?Refrigerants are not allowed to be released due to environmental concerns.
Step 8: You can open the windows and doors.
This allows air to move without restriction.It is very dangerous to breathe the air if you don't open your doors and windows.Kids and pets should be placed in a safe room with the door closed when the air is moving.They will not be able to breathe in fumes.Make sure your air conditioning or heating unit is turned off before you use it.
Step 9: Make sure to shake your can.
Many brands ofrigerant sprays can be found at hardware stores.Just like any other spray can, you will want to shake it before using it.Take it away from the spray you want to do.If you hold the can upright, the liquid will leak out.
Step 10: The refrigerant should be sprayed on the epoxy.
The spray can drop the temperature very quickly.It will turn brittle when it is frozen.Do not touch the area you are spraying.Before spraying, make sure your gloves and goggles are secure.Children and pets should not be near the area.
Step 11: Remove the brittle epoxy.
Use a rubber mallet or hammer to hit the epoxy.It should be cold enough that it will break off easily.You will want to dump the crystals into the trashcan after you sweep them up.If you want to make sure you get rid of the remaining crystals, you can use a vacuum cleaner.Don't put too much pressure on the surface.If it doesn't break apart easily, add more spray cooler to chill it even more.
Step 12: Put on goggles, safety gloves and a mask.
It is important to put on safety equipment that protects your eyes, lungs, mucus membranes, and skin before you work with any chemical agents.Put on a pair of goggles that cover your eyes completely and sit against your skin, without any openings where air can get through.You will need rubber gloves that extend at least 3 inches past your wrists, as well as a respirator for the chemicals you are using.
Step 13: Go inside the windows and doors.
This is important because you need to breathe.The harmful fumes of the chemicals will be carried through the open doors and windows.Chemical agents are hazardous to your health if your windows and doors remain closed.Make sure to turn off your air conditioning or heating unit if you want fresh air.
Step 14: You can choose a chemical that will make it softer.
It is important that the chemical agent does not damage the surface.Chemicals can damage cloth, plastic or vinyl.The strong chemicals can eat away at the surface.You should always reference the Material Safety Data Sheets for all chemicals.Handling instructions and the correct PPE will be included in the MSDS.Stay away from Class 3 and 4 oxidizers.These agents can cause a fire.Try a thinner.If you use a paint thinner that has acetone in it, be prepared to let the epoxy and object to which it is stuck soak for at least an hour.A stripping agent can be used.Most hardware stores carry these.
Step 15: The stripping agent should be applied.
You can either put the agent on a cloth or on the floor.Make sure that there is enough agent to get onto the epoxy.Wait at least an hour after the agent has been applied to come back to it.Work in small steps at a time.The chemical agent won't work as well if the area is too wide.Children and pets should not be around when you apply the chemical agent.
Step 16: You can mix a cleaning solution.
After the chemical stripping agent has sat for an hour, you will need to remove it.In a medium sized bucket, mix together 1 gallon of hot water and 50-75 grams of trisodiumphosphate.You can either use a sponge or pour the mixture onto the stripping agent.Allow it to sit for at least 5 minutes.
Step 17: Remove the epoxy from the surface.
The plastic scraper is strong.You will want to put the epoxy in a paper towel and throw it away.The goal is to keep the chemical agents away from you.If the remaining epoxy is still stuck to the surface, soak it in the chemical for a while before trying to remove it.You can wash the area with a rag soaked in warm water and soap.Children and pets should not be exposed to chemicals in the house.
