Paint remover STRIAL series

Published on : Apr 2, 2019 / Revised on : Oct 17, 2026

Swells and Strips Tough Cured Coatings Without Damaging the Metal Substrate.
Cured Paint Stripper "STRIAL Series"

Using a proprietary swelling-and-stripping mechanism different from chlorinated solvents, the STRIAL Series removes cured paint firmly adhered to painting jigs and products. It reduces the risk of metal corrosion and premature deterioration of the stripping bath, significantly improving safety in the stripping process and the efficiency of bath management.

Product Features

Extends Jig Life Without Damaging the Metal Substrate

Unlike incineration, which can cause thermal distortion, or shot blasting, which can cause wear, the STRIAL Series strips coatings without damaging the underlying metal. It can be used not only for painting jigs but also for stripping defective coatings from delicate products made of materials such as aluminum and magnesium for rework.

Optimal Product Selection for Different Materials and Paint Conditions

We select the most suitable product from a broad lineup according to the base metal of painting hangers and jigs, the chemical composition of the paint, and whether the coating is cured or uncured. We can also propose solutions for requirements such as neutral paint strippers and lower-temperature stripping processes.

Designed with Workplace Safety and Regulatory Compliance in Mind

Designed with workplace safety and compliance in mind. With no flash point, the product helps reduce flammability risks and supports safer, easier handling and storage in manufacturing facilities.

Vapor Loss During Heating
Vapor loss during heating can be reduced by using an evaporation inhibitor. In addition to suppressing vapor loss, an evaporation inhibitor helps maintain the balance of the stripping bath, reducing the effort required for bath management. It can also lower running costs and help retain bath heat, reducing energy costs.

Are You Facing These Coating Removal or Bath Management Problems with Painting Jigs and Rework Products?

Premature stripper deterioration and frequent bath replacement
Paint strippers that dissolve coatings can deteriorate quickly and generate sludge, resulting in high chemical replacement costs and burdens associated with waste treatment.
Thermal distortion and substrate wear caused by incineration or shot blasting
Repeated physical blasting or incineration can deform or wear expensive painting jigs, shortening their service life. It can also contribute to contaminants being carried into the painting line.
Corrosion or damage to jigs and rework products such as aluminum and copper components
Strong chemicals can attack not only painting hangers but also the substrates of metal products such as aluminum and copper that need to be repainted, making rework difficult.
Severe vapor loss from the stripping tank and complicated bath-balance management
Heat and vapor generated during heated immersion can cause stripping-bath components to evaporate, disrupting the chemical balance and significantly reducing stripping performance.
Challenges in complying with chemical regulations and maintaining workplace safety
Managing strippers containing chlorinated solvents such as dichloromethane or substances regulated as poisonous or deleterious can create burdens related to chemical management, work-environment monitoring, and occupational safety measures.

How to Use

・Preheat STRIAL in the stripping tank.
　※The stripping temperature varies depending on the STRIAL product.

・Immerse the workpiece to be stripped.

・After immersing for the required period, remove the workpiece and rinse away the loosened coating and stripper using a water jet or similar method.
　※The required stripping temperature and time vary depending on coating thickness and paint type. Please determine suitable conditions by conducting a stripping test in advance.

	Technical Solutions Preventing Painting Defects: Examples of Cratering Cratering occurs when a contaminant with lower surface tension than the liquid paint contacts the coating. The contaminant is drawn across the paint surface, causing the coating film to become thinner in that area. This page introduces numerous examples of cratering defects.
	Technical Solutions Preventing Painting Defects: Examples of Particle Contamination Particle defects can be caused by paint itself as well as small contaminants such as dust, fibers, and insects. Electrostatic attraction can make these problems more severe. Solving particle defects requires observation and an understanding of the surrounding environment. Review your painting process using these examples of particle defects.

Contact Us for Preliminary Swelling / Stripping Tests and Samples

Are you experiencing problems in your stripping process, such as rapid deterioration of a dissolving-type paint stripper and frequent bath replacement costs, difficulty removing only the coating from rework products such as aluminum or copper without damaging the substrate, or increased running costs caused by evaporation loss from the stripping bath?
We can also conduct preliminary stripping tests to select the most suitable grade for your jig or workpiece material and paint condition (cured or uncured). Please feel free to contact us.
