What Is Disodium Octaborate Tetrahydrate CAS 12280-03-4?

Disodium Octaborate Tetrahydrate CAS 12280-03-4 is a white powder, soluble in water. Colorless, odorless, non-volatile, non-corrosive to metals, can be used with agricultural fertilizers, pesticides and other products.

Disodium octaborate tetrahydrate (DOT) has no strong oxidizing or corrosive properties, is chemically mild, and does not react with most metal ions (except for a few heavy metals such as silver and lead), and has good compatibility. DOT can dissociate borooxide ions in water and has a certain complexing ability, which can form stable complexes with polyhydroxy compounds (such as glycerol and sugar alcohols). Boron is an essential trace element for plants. Disodium octaborate tetrahydrate powder can be quickly absorbed and utilized by plants and is less likely to cause boron poisoning (safer than boric acid and anhydrous borax). Disodium octaborate tetrahydrate is environmentally friendly, can be slowly degraded under natural conditions, and is of low toxicity to aquatic organisms, meeting environmental protection requirements.

What is DMTDA Cas 106264-79-3?

Dimethyl Thio-toluene Diamine (DMTDA), also known as Ethacure 300 or DMTDA Amine, is a liquid aromatic diamine curative widely used for polyurethane (PU) elastomers, polyurea coatings, and epoxy systems.
With moderate reactivity, excellent mechanical properties, and good processing flexibility, DMTDA has become one of the most popular alternatives to MOCA and other conventional aromatic diamines.

DMTDA is a new type of polyurethane elastomer curing and crosslinking agent, in which there are mainly two isomers, namely the mixture of 2,4 – and 2,6 – dimethylthiotoluene diamine (the ratio is about 77~80/17~20). Compared with the commonly used MOCA, DMTDA amine is a liquid with low viscosity at normal temperature, DMTDA amine can be used for construction operation at low temperature, and has low chemical equivalent.

Application

1. Dimethyl thio-toluene diamine is a new type of liquid curing agent for polyurethane elastomer. It is widely used in polyurethane casting, coating, RIM, SPUA, polyurethane tire and adhesive for chain extension or cross-linking, and is also a curing agent for epoxy resin.

2. As hardener, when added to TDI and MTDI two-liquid polyurethane elastomers, it must be added at the rate of 10%. In the construction and civil industry, it is often used as an additive for fireproof coating (layer top and side wall), corrosion protection of metal materials (coating on the inner wall of iron pipe), and other aspects. The polyurethane product that can react with other substances without any treatment is superior to the product of MOCA (Mocha) hardener.

3. Used for polyurethane printing rubber scraper, oil pipe cleaning scraper, etc., to improve the oil resistance of polyurethane, and the volume expansion rate is also low.

4. Ethacure 300 (DMTDA) is widely used in electronic encapsulation and potting compounds due to its low viscosity, thermal stability, and uniform curing behavior.
It improves electrical insulation, thermal shock resistance, and longevity of the encapsulated parts.

5. In addition, Dimethyl thio-toluene diamine is widely used in the textile, paper and printing industries. Dimethyl thio-toluene diamine can be said that it has a broad market from the aviation and aerospace industry to the general civil industry.

What is Carbomer 940?

Carbomer is an organic compound, also known as polycarboxylate, which is a polymer formed by chemical crosslinking of acrylic acid or acrylate with allyl ether, including polyacrylic acid (homopolymer) and long-chain alkanol-acrylate polymer (copolymer). Its molecular structure contains 52~68% acid groups, so it has certain acidity, hydrophilicity and can be dissolved in water.

Application

Clinically, the main functions and functions of carbomer are to protect the skin, resist ultraviolet rays, reduce viscosity, and reduce inflammation and sterilization. Carbomer, also known as acrylic resin, is a commonly used cosmetic additive.
1. Protect the skin: It has a certain affinity with the skin. Adding skin care products can reduce irritation and damage to the skin and mucous membranes, thereby protecting the skin.
2. Resist ultraviolet rays: It can enhance the skin’s ability to resist ultraviolet rays to a certain extent.
3. Reduce viscosity: It can reduce viscosity, maintain the stability of effective cosmetic substances, and make it easier for the skin to absorb.
4. Anti-inflammation and sterilization: Carbomer is a natural medicinal ingredient that has certain sterilization and anti-inflammatory effects and can fight dermatitis to a certain extent.

At present, our factory has upgraded carbomer 940 to carbomer 980. Because the original Carbomer 940 is synthesized from acrylic acid and benzene, it contains a certain amount of benzene residue, which is a toxic substance.
In order to be safer, we use ethyl acetate and cyclohexane to make Carbomer 980, so that our product ingredients will be safer and the effect will be better.
Of course, Carbomer 980 is the same as Carbomer 940 in terms of viscosity and light transmittance.
If you have no special requirements on light transmittance and viscosity, we also recommend Carbomer 680, the price will be cheaper.
