iHeir-YQ Paint Antifungal & Antibacterial Agent

Product Overview

iHeir-YQ is a highly efficient, non-toxic, broad-spectrum antifungal and antibacterial agent specially designed for paints, PU, latex paints, polymer emulsions, pigments, and various oil-based coating systems. This product is also suitable for in-can preservation and dry film antifungal protection of printing inks and other organic products. Extensive experiments and practical applications have proven that iHeir-YQ has excellent biocidal and preservative functions for copolymers such as acrylics, polyvinyl acetate, and styrene butyl acrylate, and exhibits outstanding compatibility with organic/inorganic components in the system. With an active ingredient concentration as high as 79.5%, it achieves significant efficacy at low addition levels, effectively protecting coatings from mold growth in humid environments over long periods.

‌Frequently Asked Questions

Q：What is the recommended addition level of iHeir-YQ in paint formulations? +

A： The recommended addition level is 1%–1.5% of the total formulation weight. This low dosage is effective due to the product's high active ingredient concentration of 79.5%, ensuring significant antifungal and antibacterial protection while keeping costs low.

Q：Is iHeir-YQ safe for use and does it contain formaldehyde? +

A： iHeir-YQ is formaldehyde-free and does not contain formaldehyde-releasing substances, making it safe and environmentally friendly. Toxicological data shows low acute oral and dermal toxicity (LD50 values around 3500–3700 mg/kg). At use concentrations, it causes no skin irritation or sensitization, and it rapidly degrades into harmless substances in the environment.

Q：How should iHeir-YQ be added to paint and stored? +

A： iHeir-YQ can be added directly during the grinding or paint mixing stage, and it should be mixed thoroughly for uniform dispersion. For storage, keep it at room temperature in a well-ventilated indoor area, using 25 kg or 160 kg plastic drums. Do not use unlined metal containers for packaging.
