Leather & Fabric Protector - Fast-Acting - Type FH917

GRASi® FH917

GRASi® FH917 is a fast-acting waterproofing agent, specially suitable for various types of leather and fabrics. This product uses next-generation nanotechnology to inhibit water absorption of substrates through hydrophobic treatment. It can significantly reduce surface energy, enhance water-repellent performance, and create an attractive beading effect on the surface. With ultra-low surface tension, its nano-scale active ingredients can penetrate the substrate, adhere to the pores, and bond firmly with them.

Features

  • Excellent waterproof and stain protection performance.
  • Prevents moisture, dampness, and liquid water from penetrating the substrate.
  • Does not alter the appearance or color of the substrate surface.
  • Chemically bonds for long-lasting protection.
  • Cures quickly and can be put into use rapidly.
  • Environmentally friendly, breathable, and safe.
  • Excellent performance under high and low temperatures (-50℃ to 200℃).
  • Environmentally friendly.

Application Instruction

GRASi® FH917 can be used directly and is suitable for waterproofing methods such as spraying or soaking.

  • The substrate surface must be clean and dry.
  • Apply using appropriate low-pressure spraying at a distance of 10-15 cm; or use an airless spray gun.
  • Coat evenly until the substrate is completely saturated.
  • Avoid contact with moisture or rain, and let it air dry naturally.
  • After 24 hours of full curing, it will form excellent water-repellent performance.
  • It is recommended to use within a temperature range of 2°C-45°C (35.6-113°F).
  • Maximum coverage is about 10 square meters per liter, depending on the substrate density.
