Anti-Graffiti Film Solutions for Glass and Signage Protection in Medan, Indonesia

The evolution of Anti-Graffiti Film technology has been driven by the escalating need to protect high-traffic urban surfaces from deliberate damage. Initially developed as a niche solution for transit authorities in major cities, the technology has matured into a versatile protective layer for glass and signage. For Medan, a city experiencing rapid commercial growth and increased foot traffic in areas like Medan Mall and Sun Plaza, the adoption of anti-graffiti films aligns with global best practices in facility management. Early iterations of these films focused solely on physical barrier protection, but modern advancements incorporate UV stabilization, enhanced adhesive systems, and multi-layer construction. The introduction of 4-mil polyester substrates, as specified by KASKI, provides superior tensile strength (34,900 psi per ASTM D882) and puncture resistance (93 lbs per ASTM D4830), making them suitable for both interior retail displays and exterior bus stop shelters. The development of semi-permanent adhesive technology allows for clean removal and replacement without damaging the underlying glass, a feature particularly valuable for Medan’s leased commercial spaces where landlord approvals are required for modifications. As the industry moves toward sustainable building practices, these films contribute to reducing waste by extending the lifecycle of existing glass installations rather than requiring full replacements.

KASKI’s Anti-Graffiti Film portfolio includes both PET (Polyester) and TPU (Thermoplastic Polyurethane) variants, each engineered to address specific surface protection needs in Medan’s diverse commercial and industrial environments.

PET Anti-Graffiti Film for Glass Surfaces

The PET variant, a 4-mil optically clear polyester film, is the primary solution for glass windows, storefronts, and public facility glazing. Its key advantages include: Chemical Resistance: The durable acrylic coating prevents acid etching from glass etchants and solvent-based markers, common tools used by vandals. Easy Cleanability: Graffiti materials such as spray paint and permanent markers do not bond to the surface; after drying, they can be wiped off with a microfiber cloth and isopropyl alcohol without leaving residue. UV Protection: With less than 1% ultraviolet transmission (per ASTM E903), the film protects retail merchandise and interior furnishings from fading, a critical factor for Medan’s high-sunlight exposure. Cost Efficiency: Replacement of a vandalized film section costs a fraction of new glass installation, saving businesses thousands of rupiah annually. Semi-Permanent Adhesive: Allows for easy removal and reapplication without damaging the glass substrate, facilitating quick restoration after severe vandalism.

TPU Anti-Graffiti Film for Signage and Irregular Surfaces

For Medan’s outdoor advertising signs, bus shelter graphics, and event displays, the TPU variant offers superior conformability and self-healing properties. Key advantages include: Flexibility: TPU conforms to curved, textured, or uneven surfaces such as brick walls and concrete pillars, which are common in Medan’s mixed-use building facades. Self-Cleaning Coating: The easy-to-clean top layer prevents ink and paint from penetrating the substrate, ensuring that even aggressive tagging can be removed without harsh chemicals. Optical Clarity: Maintains the vibrancy and readability of printed graphics, vital for advertising effectiveness in high-traffic areas like Lapangan Merdeka. Durability: The material resists abrasion and weathering, with a minimum lifespan of three years under outdoor conditions, reducing maintenance cycles for property managers. KASKI provides competitive pricing and superior product quality for both PET and TPU lines, ensuring Medan clients receive tailored protection without budget overruns.

KASKI’s Anti-Graffiti Film meets rigorous international standards, ensuring reliable performance in Medan’s tropical climate. Below are the key technical parameters validated by independent testing:

• Film Material: Optically clear 4-mil (0.10 mm) polyester with durable acrylic abrasion-resistant coating and pressure-sensitive weatherable acrylate adhesive.
• Abrasion Resistance (ASTM D1044): Less than 5% increase in transmitted light haze after 100 cycles with 500-gram weight and CS-10F Calibrase wheel, ensuring long-term optical clarity.
• Visible Light Transmission (ASTM E903): 86% when applied to 1/4-inch clear glass, maintaining natural lighting and visibility for retail displays.
• Ultraviolet Transmission (ASTM E903): Less than 1%, protecting interior assets from fading and reducing skin cancer risks for occupants.
• Tensile Strength (ASTM D882): 34,900 psi, with break strength of 136 lbs per inch width, providing robust resistance against impact and tearing.
• Puncture Strength (ASTM D4830): 93 lbs, preventing penetration from sharp objects and accidental breakage.
• Flammability (ASTM E84): Flame Spread Index of 25 (maximum) and Smoke Developed Index of 450 (maximum), meeting building code requirements for commercial spaces.
• Warranty: 5 years for outdoor installations and 10 years for indoor installations, reflecting product longevity and manufacturer confidence.

These parameters ensure that KASKI films withstand Medan’s high humidity, intense sunlight, and frequent rainfall without delamination or yellowing. The adhesive system is designed for clean removal after the warranty period, facilitating easy restoration of glass surfaces.
