The PALCCOAT CLEAR Series has been certified with the SIRIM Eco Label and the MyHIJAU Mark.

In addition, the PALCCOAT coating application service that utilizes this product has also been registered as a certified service.

The SIRIM Eco Label and the MyHIJAU Mark obtained by the PALCCOAT CLEAR Series are both rigorous and internationally reliable green

certifications administered by the Malaysian government and its related agencies. These certifications verify that our products meet stringent environmental performance and safety standards.

Certified Through Rigorous Evaluation Based on International Standards

The SIRIM Eco Label is a third-party certification system compliant with ISO 14024 (environmental labeling).

Products are evaluated across a wide range of criteria, including safety, environmental impact, manufacturing processes, and functional performance.

Because the assessment is conducted objectively by an independent organization, the certification is recognized for its high level of international credibility.

The MyHIJAU Mark is Malaysia’s official green recognition endorsed by the government, integrating certified eco-friendly products and services under a unified national directory. It signifies compliance with verified environmental performance standards and supports sustainable procurement initiatives across the country.

What is the SIRIM Eco Label?

The SIRIM Eco Label is a third-party environmental certification administered by SIRIM, Malaysia’s national standards and quality authority.

It complies with ISO 14024 (Type I environmental labeling) and evaluates products comprehensively based on safety, environmental impact,

quality, and manufacturing processes. Only products that meet its stringent criteria are certified.

SIRIM (Standards and Industrial Research Institute of Malaysia) is a government-affiliated organization responsible for national standardization and product quality certification.

Its Eco Label program assesses products across multiple categories, including:

• Environmental impact reduction
• Product safety
• Functional performance
• Compliance with industrial and international standards

The SIRIM Eco Label is recognized as one of the most reliable environmental certifications in the Asia-Pacific region and is widely used as a benchmark in the evaluation of building materials, interior materials, and coating products.

What is the MyHIJAU Mark?

The MyHIJAU Mark is Malaysia’s only official government-endorsed green certification, established to identify and promote environmentally preferable products and services.

It serves as a national framework for certifying eco-friendly solutions based on Malaysia’s sustainability policies.

Products and services applying for the MyHIJAU Mark are evaluated on criteria such as:

• Energy efficiency
• Product safety
• Environmental impact reduction

Only those that meet the required environmental performance standards are approved and listed in the MyHIJAU Directory, the country’s unified registry of certified green products and services.

The MyHIJAU Mark is also widely used in Malaysia’s Green Public Procurement (GGP) programs, where certified products are often given priority in government and public-sector purchasing. This makes it a highly practical and influential certification within the Malaysian market.

In recent years, particularly in the fields of architecture and environmental engineering, interest in Indoor Air Quality (IAQ) has been growing worldwide.

While energy efficiency, airtightness, and high insulation performance in buildings have advanced, chemical substances and volatile organic compounds (VOCs) that accumulate indoors are once again being recognized as potential health risks.

The Core of IAQ Research: “Ventilation + Materials + Chemical Substances”

In academic IAQ research, rather than relying on a single countermeasure,

• ●Ventilation design
• ●Emissions from building and interior materials
• ●Chemical reactions occurring indoors

a comprehensive and integrated perspective has become the mainstream approach.

Particular attention is being paid to substances such as:

• ●Formaldehyde
• ●TVOC (Total Volatile Organic Compounds)

which are known to pose risks even at low concentrations when exposure occurs over long periods.

Photocatalysts in IAQ Research as a “Complementary Technology”

Within the IAQ research field, photocatalysts are not treated as a “universal air purification solution,” but are instead positioned as:

• ●A supplementary measure that assumes proper ventilation
• ●A surface-based reaction control technology for building materials

This perspective is widely accepted in academic discussions.

Recent studies have focused on:

• ●Reactivity under low-light indoor conditions
• ●Durability and longevity of photocatalytic coatings formed on surfaces
• ●The presence or absence of by-products

These aspects are being examined in greater detail.

Academic Clarification of the Term “Decomposition”

Even in IAQ research, photocatalytic reactions are not regarded as simple “decomposition,” but rather as a continuous series of oxidation reactions.

As a result, careful discussion is given to:

• ●Intermediate products generated during the reaction process
• ●The potential for re-emission within indoor spaces

For this reason, avoiding overly simplified expressions of photocatalytic effects is considered important from an academic standpoint.

“Durability” and “Management” in Indoor Environments

In the IAQ field, greater emphasis is placed on long-term performance rather than short-term effects, including:

• ●Whether performance can be maintained over extended periods
• ●Deactivation caused by the accumulation of indoor pollutants
• ●The relationship with cleaning and maintenance practices

Such operational and management perspectives are considered essential.

The lifespan and effectiveness of photocatalytic coatings vary depending on usage conditions and the surrounding indoor environment, making it difficult to define them with a single uniform value.

Approaches to Performance Evaluation and Measurement

In IAQ research, it is pointed out that evaluations should clearly distinguish between:

• ●Laboratory-based testing
• ●Measurements conducted in actual living environments

This distinction is considered essential.

In real-world environments, numerous factors influence results, including:

• ●Temperature and humidity
• ●Ventilation frequency
• ●Human occupancy and movement

Therefore, careful interpretation of measurement results is required.

PALCCOAT’s Perspective on IAQ

When applying photocatalytic technology as an IAQ countermeasure, PALCCOAT adheres to the following principles:

• ●Considering the overall design of the indoor environment as a prerequisite
• ●Positioning photocatalysts as a complementary technology
• ●Avoiding excessive emphasis or exaggeration of measurement results

These principles form the foundation of our approach.

Improving indoor air quality is not an issue that can be resolved by a single technology alone; it should be addressed as a challenge that requires the combination of multiple elements.

PALCCOAT will continue to share information that bridges academic knowledge with real-world application, construction, and operational practices related to IAQ.
