iHeir-M300 Odorless Solvent-based Water Repellent

Product Overview

iHeir-M300 is a solvent-based fluoropolymer water and oil repellent, widely used for surface treatment of various substrates such as textiles, leather, synthetic leather, paper, wood, and stone. After treatment with iHeir-M300, the substrate achieves excellent water repellency, water resistance, oil repellency, and dust resistance, while maintaining its original appearance, breathability, and touch, without altering the material’s natural characteristics.

Product Features

High-Efficiency Protection: Imparts excellent water repellency, oil repellency, and dust resistance to the substrate surface; liquid stains are less likely to adhere or penetrate.
Preserves Original Properties: The original appearance, hand feel, and breathability of the substrate are not affected after treatment.
Wide Range of Applications: Suitable for textiles, natural leather, synthetic leather, paper, wood, stone, etc.
Room Temperature Application: Dries at room temperature after coating, easy to operate.

Application Method

1. Pre-use Confirmation and Dilution

iHeir-M300 may solidify or settle at temperatures below 15°C, which is normal. Warm it in a warm water bath and mix thoroughly until the liquid returns to a uniform, transparent state.
Dilute at a ratio of iHeir-M300 : Solvent = 1 : 4. Petroleum-based solvents (e.g., n-decane, boiling point 150–200°C) are recommended. Recommended solvent: EXXOL D40.

2. Coating Application

Ensure the substrate is thoroughly dry.
Apply the diluted treatment solution evenly onto the substrate surface at approximately 200 g/m².
Apply at room temperature. Depending on the substrate, gently wipe the surface about 10 minutes after application if necessary.

3. Drying

Allow to dry thoroughly at room temperature for 24 hours.

Precautions

Low temperatures (below 15°C) may cause coagulation or sedimentation; warming and mixing restores usability.
The work area must be well-ventilated (local exhaust is recommended).
Wear protective goggles, gloves, and a mask during handling. Avoid splashing into eyes, contact with skin, or inhalation of vapor.
This product is flammable. Observe relevant fire safety regulations during use and storage.
Keep container tightly closed during storage to prevent solvent evaporation or contamination.

‌Frequently Asked Questions

Q：What is the recommended dilution ratio for iHeir-M300? +

A： The recommended dilution ratio for iHeir-M300 is 1 part iHeir-M300 to 4 parts solvent (1:4). It is recommended to use petroleum-based solvents such as n-decane (boiling point 150–200°C) or the recommended solvent EXXOL D40.

Q：How should iHeir-M300 be applied and dried? +

A： Ensure the substrate is thoroughly dry before application. Apply the diluted treatment solution evenly onto the substrate surface at approximately 200 g/m². Apply at room temperature, and if necessary, gently wipe the surface about 10 minutes after application. Allow the treated substrate to dry thoroughly at room temperature for 24 hours.

Q：What should be done if iHeir-M300 solidifies or settles at low temperatures? +

A： If iHeir-M300 solidifies or settles at temperatures below 15°C, this is normal. Warm the product in a warm water bath and mix thoroughly until the liquid returns to a uniform, transparent state before use. Additionally, avoid prolonged storage at low temperatures (below 15°C) and store the container tightly closed in a cool, well-ventilated area away from ignition sources.
