iHeir-M8 Bamboo and Wood Fungicide – An Efficient, Broad-Spectrum, Non-Release Type Long-Lasting Antimicrobial Treatment Agent for Bamboo and Wood

iHeir-M8 Bamboo & Wood Antifungal Agent

Product Overview

iHeir-M8 is a high-efficiency, broad-spectrum, non-leaching long-acting antimicrobial treatment agent for bamboo and wood. It is a transparent amber liquid whose main active ingredients are a mixture of 5-Chloro-2-methyl-4-isothiazolin-3-one (CMIT) and 2-Methyl-4-isothiazolin-3-one (MIT), along with acetic acid. It utilizes a mechanical sterilization mechanism, forming chemical bonds with the surface of bamboo, wood, rattan, grass, and other substrates at room temperature to create a durable and stable antimicrobial protective layer, effectively preventing mold, rot, and insect damage without inducing microbial resistance.

Key Features

• Non-Leaching & Long-Lasting: The antimicrobial components do not leach, migrate, or get consumed by microorganisms, offering durability matching the product’s service life.

• Mechanical Sterilization – No Resistance: Physically disrupts microbial cell membranes, unlike traditional leaching-type chemical fungicides, maintaining high efficacy even after long-term use.

• Broad-Spectrum Antimicrobial: Effectively inhibits Gram-positive bacteria (e.g., Staphylococcus aureus), Gram-negative bacteria (e.g., Escherichia coli, Pseudomonas aeruginosa), mold (Aspergillus niger, Aspergillus flavus, Penicillium, etc.), yeast, algae, and other microorganisms.

• Room-Temperature Bonding, High-Temperature Stability: Reacts at room temperature (e.g., during spraying); the efficacy is not easily compromised by subsequent high-temperature environments.

• Anti-Insect Function: Also provides insect-repellent properties, reducing the risk of insect damage.

Physical & Chemical Specifications

Safety

iHeir-M8 has passed 18 rigorous safety tests (including acute oral/dermal toxicity, eye mucosa irritation, skin irritation, fish toxicity, human skin contact, teratogenicity, environmental decomposition, etc.) and is certified by the U.S. Environmental Protection Agency (EPA) and EU REACH. Key toxicological data:

• Acute Oral Toxicity (Rat): LD50 = 3700 mg/kg (Low toxicity)

• Acute Dermal Toxicity (Rabbit, female): LD50 = 3600 mg/kg

• Acute Dermal Toxicity (Rabbit, male): LD50 = 3500 mg/kg

• The concentrate is moderately irritating to skin; at use dilution, it is non-irritating.

• Environmental decomposition: Rapidly and completely decomposes into harmless substances, low environmental risk.

Main Applications

• Bamboo woven goods, wooden products, rattan ware, miscanthus products, sunflower leaves, grass woven products

• Roofing materials (roof panels, roof beams, shingles, shakes)

• Wooden pallets, wooden furniture, etc.

Product Benefits

• Prevents degradation and discoloration caused by bacteria, mold, algae, etc.

• Inhibits odor-causing bacteria, keeping products “fresh” and eliminating unpleasant smells.

• Extends product service life.

• Keeps items clean and hygienic, with added insect-repellent effect.

• Good compatibility with various substrates and processes.

Application Methods

Immersion Method (Recommended)

• Prepare the immersion solution at a ratio of 1 part iHeir-M8 : 20 parts water.

• Completely immerse the bamboo/wood products in the solution, ensuring they remain below the liquid surface.

• Immerse for approximately 1–10 minutes until the product weight gain reaches 10% – 20%.

• Remove, drain excess solution, and air dry or sun dry before packaging and storage.

• The solution can be reused; it is recommended to use within 1 month.

Spray/Brush Method

• Dilute with water at a ratio of 1:20, mix well.

• Evenly spray or brush onto the product surface, ensuring complete coverage.

• Allow to air dry naturally.

Antifungal Duration

When the moisture content of treated products is below 25%, the continuous antifungal effect can last for over 1 year.

Precautions

• Shake well after diluting with water before use. Some floating matter on the surface after prolonged standing is normal; shake well before use.

• The diluted solution should ideally be used within 1 month.

• This product complies with REACH requirements. The concentrate may cause skin sensitivity in some individuals; wearing rubber gloves is recommended during handling.

Antifungal Efficacy Test (Refer to GB/T 18261-2013)

• Simple comparative test: Place treated and untreated samples together in a dark, humid environment. Observe after 7–15 days.

• Accelerated test: Place samples in petri dishes containing agar, then in a constant temperature and humidity chamber (90% RH, 28°C). Preliminary results can be obtained within 3–7 days.

Packaging & Storage

• Packaging Specifications: 25 kg/drum

• Storage Conditions: Protect from moisture and light.

• Shelf Life (Concentrate): 3 years
