A resin remover or resin stripper (41914) is a substance, typically a solvent or cleaner, intended to dissolve and eliminate uncured or hardened resin from surfaces, tools, and various metals.
What is the Purpose of a Resin Stripper?
Resin removers work by breaking down the molecular structure of resin, facilitating its removal by wiping or rinsing often times using aerosol resin remover spray like Resin Stripper - 41914.
Frequent applications of a Resin Stripper...
Cleaning up resin spills: Efficient for eliminating uncured resin from work areas, tools, and clothing.
Maintaining tools and equipment: Ensures that tools and equipment used with resin remain clean and free of residue.
3D Printing: Utilized for removing uncured resin from 3D printers and components.
Mold Cleaning: Certain resin removers like Heat Tech's 41914 are formulated specifically to eliminate resin buildup on molds.
Types of Resin Removers...
Alumilite Amazing Resin Remover: Widely favored for its eco-friendliness and skin-friendly nature.
Isopropyl Alcohol (IPA) - 47212 from Heat Tech Systems: A widely used solvent for cleaning uncured resin, particularly in 3D printing and Injection Mold Cleaning.
Acetone X-EMPT - 47410 from Heat Tech Systems: It can be utilized to remove cured epoxy resin; however, exercise caution as it may harm certain surfaces.
Water Softener Resin Cleaner: Items such as ResCare are formulated to eliminate impurities that salt alone cannot, enhancing the performance of water softeners.
Tom's Resin Remover: A natural cleaner made from plant-based oils for tumblers and accessories.
Applying Heat Tech System's Resin Stripper - 41914
To achieve the best results, you should:
1. Make sure your mold is warm (ideally above 170ºF) rather than cold, then generously spray Resin Remover over the "plate out" area, ensuring the entire surface is covered.
2. Lightly apply a mold release, like 40910 to the entire mold to prevent parts from sticking to the mold except where there is residue; remember to spray the core side of the mold where there are no ejector pins
3. After applying both the Resin Remover and mold release, close the mold.
4. Maintain the mold's warmth and allow it to rest for 90 to 120 seconds
5. Begin molding and remove parts until the residue is gone—this usually takes four or five shots. If the buildup is especially heavy, repeat the process.
To maintain your mold's optimal condition, avoid leaving the Resin Remover on a cold mold overnight. This hygroscopic, slow-evaporating substance will draw moisture from the air, leading to rust on your mold's surface.
To eliminate Resin Remover from a cold mold, use a Slide Mold Cleaner, Slide Alcohol IPA, or a Slide Acetone to clean the mold. Then, immediately apply a rust preventive like Slide’s Mold Shield - 42910 or No Rust - 40212 Aerosol Sprays.
To clear blocked internal vents, users should:
1. Apply a thick coat of Resin Remover to the internal vent areas
2. Seal the mold prior to injecting a small amount of resin, which will evaporate the Resin Remover resulting in a clean, residue-free vent. Resin Remover or Resin Stripper is offered in aerosol form and in bulk liquid quantities (1, 5, and 55 gallons).
