RFD-10 mildew and antibacterial agent, a green and environmentally friendly soft plastic specialty - Guangyuan Ruifeng New Materials

Category: Anti-mildew and antibacterial agent

Release Time: 2020-06-11

Summary: In the application of fungicides, in the past, people often used organomercury, organotin, organoarsenic, phenols (including halogenated phenols), and formaldehyde compounds. The first few are highly toxic and pollute the environment, so they have been eliminated, and are only used in limited quantities in antifouling paints for ship bottoms; the high volatility, high reactivity, and toxicity of formaldehyde limit its use. After the 1970s, the main fungicides and preservatives used include sodium pentachlorophenate, carbendazim, chlorothalonil, thiram, Vinclozolin, and methylenebisthiocyanate.

I. Background Introduction

In the application of mildew inhibitors, in the past, people often used organomercury, organotin, organic arsenic, phenols (including halogenated phenols), and formaldehyde compounds. The first few are highly toxic and pollute the environment, and have been eliminated, only being used in limited quantities in antifouling paints for ship bottoms; the high volatility, high reactivity, and toxicity of formaldehyde limit its use. After the 1970s, the main fungicides and preservatives used include sodium pentachlorophenate, carbendazim, chlorothalonil, thiram, vinclozolin, and methylenebisthiocyanate. Sodium pentachlorophenate is highly toxic and has been banned; the latter few have poor water solubility and their fungicidal and preservative effects are not good, and only because of their low price do they still have some market. Now, both domestically and internationally, there is a trend towards using highly effective, broad-spectrum, low-toxicity, water-soluble fungicides and preservatives. This type of fungicide has high fungicidal efficiency (the minimum inhibitory concentration MIC of the general active ingredient against microorganisms is within a few tens of PPM), a broad fungicidal spectrum (effective against bacteria, fungi, yeasts, and algae), and is safe and reliable (LD50, rats, oral administration is generally greater than 1000 mg/kg). Isothiazolinone compounds, such as (DCOIT, 4,5-dichloro-N-octyl-4-isothiazolin-3-one), are a new type of excellent antibacterial drug that has emerged. They have the characteristics of safety, broad spectrum, high efficiency, and low toxicity. (Mildew-proof and antibacterial agent, mildew inhibitor, environmentally friendly product)

Isothiazolinone compounds are a broad-spectrum, highly effective, low-toxicity, non-oxidizing fungicide used in the oil field, papermaking, pesticide, cutting oil, leather, ink, dye, and leather industries.

II. Product Description

This product is a uniform and stable liquid product formulated with isothiazolinone derivatives (DCOIT) as the active ingredient and special adjuvants and synergists. It can be added to PVC coating slurries, PVC calendered films, PVC artificial leather coatings, PVC wallpaper, PVC plastic toys, and other soft plastic materials. It can simultaneously prevent mildew, bacteria, and algae, and is a very effective mildew-proof and antibacterial agent for soft plastic products. For use in hard products, only the amount of plasticizer needs to be reduced. (Mildew-proof and antibacterial agent, mildew inhibitor, environmentally friendly product)
