Mechanism and Chemical Properties

E-Solve 21HU and 21HUK are specialized Resin Dissolving Agents developed to handle Cured Urethane, which is typically resistant to standard solvents.

• Swelling and Dissolving: The agent penetrates the resin structure, causing it to swell and eventually dissolve or strip away from the substrate.

• Non-chlorinated Profile: The products are free from chlorinated solvents, reducing environmental impact and simplifying chemical management.

• Enhanced Dissolving Power: The E-Solve 21HUK model contains Inorganic Alkaline components, providing a more powerful chemical reaction for extremely stubborn urethane residues.

Industrial Applications

These products are technically designed for removing cured polyurethane in various manufacturing and maintenance scenarios:

• Urethane Sealant Removal: Stripping potting materials and sealants from electronic circuit boards.

• Adhesive Stripping: Removing residues from parts bonded with polyurethane-based adhesives.

• Equipment Maintenance: Cleaning hardened build-up inside urethane mixing tanks and raw material containers.

• Optical Industry: Removing polyurethane coatings from optical lenses.

• TPU Dissolution: Effective in dissolving Thermoplastic Polyurethane (TPU).

Specifications and Usage

Recommended Application Procedure

The process is performed by immersing the workpiece in E-Solve 21HU or 21HUK. The resin will begin to soften and detach over time. Applying controlled heat to the solution can significantly accelerate the dissolution rate and improve overall throughput.

Safety and Regulatory Compliance

Developed with a focus on safety standards and international regulations:

• Regulatory Status: The products are exempt from the Japanese Organic Solvent Toxicity Prevention Rules and the Specified Chemical Substances regulations. They are also non-applicable to PRTR regulations.

• Fire Safety: E-Solve 21HUK is classified as a Class 4 Petroleums No.3 - Water Soluble substance under the Fire Service Act, requiring appropriate storage in accordance with hazardous material regulations.

Frequently Asked Questions (FAQ)

Q: What specific types of urethane can this product dissolve?
A: It is technically designed for Cured Urethane, polyurethane adhesives, and Thermoplastic Polyurethane (TPU) that cannot be removed by conventional solvents.

Q: What is the most effective method for stripping?
A: The most effective method is Immersion. For faster results, the solution can be heated within a safe temperature range to catalyze the dissolving process.

Q: Are there specific storage requirements for these agents?
A: For the E-Solve 21HUK model, it is mandatory to comply with Class 4 Petroleums No.3 regulations under the Fire Service Act, which include storage in designated hazardous material areas or cabinets.
