The process begins with carefully selected high-quality kraft paper and decorative surface layers that form the core of Samrat’s HPL Cladding. These materials are chosen for their strength, flexibility, and resistance to environmental factors.

• Kraft Paper Layers – Impregnated with thermosetting resins for enhanced rigidity and durability.
• Decorative Surface Paper – Coated with high-performance resins to provide UV resistance, color stability, and design versatility.
• Overlay Protection Layer – Adds an extra protective barrier against scratches, moisture, and wear, ensuring a long-lasting finish.

 High-Pressure Lamination: Strength in Every Layer

Once the raw materials are prepared, they undergo high-pressure lamination, a process that transforms them into a solid, durable panel:

• Impregnation with Thermosetting Resins – The kraft paper and decorative layers are impregnated with advanced thermosetting resins, which enhance fire resistance, water resistance, and structural integrity.
• These resins ensure that the final product is chemically bonded, making it non-porous, stable, and highly durable.

Compression Under High Temperature & Pressure

• The impregnated layers are stacked together and subjected to high-pressure (≥1000 psi) and high-temperature (≥150°C) treatment in hydraulic presses.
• This process fuses the layers into a single, compact panel, eliminating air pockets and ensuring dimensional stability.
• The high-pressure treatment gives Samrat’s HPL a dense, non-porous surface, making it resistant to external elements like moisture, impact, and UV radiation.

Surface Hardening & Protective Coating

• A special protective overlay is applied to enhance surface durability against scratches, stains, and extreme weather conditions.
• This overlay ensures that Samrat Exterior HPL Cladding maintains its original color and texture for years, even under intense sunlight and pollution.
