CAS 1303-96-4 White Crystal Borax Na2B4O7.10H2O for Paperboard, Purity 99.9% Borax Decahydrate Used in Adhesives

1. Borax Decahydrate Introduction

Borax decahydrate, also known as sodium borate decahydrate or simply borax, is a naturally occurring mineral compound that is often used in various household and industrial applications. It is composed of sodium, boron, oxygen, and water molecules.Borax decahydrate is a chemical substance with the molecular formula Na2B4O7 · 10H2O. It is a semi transparent colorless crystal or crystalline white powder. Borax decahydrate has no odor and a salty taste. When heated to 350-400 ℃, borax decahydrate will lose all its crystalline water and become anhydrous borax. Borax decahydrate is soluble in water and also in glycerol, but insoluble in alcohol. Its aqueous solution is weakly alkaline and appears colorless glassy when melted.

In the realm of adhesives, borax decahydrate, a compound also known as sodium borate decahydrate or simply borax, can serve various roles and offer several benefits. Here's how borax decahydrate is commonly used in adhesives:

1. Cross-linking Agent: Borax decahydrate can act as a cross-linking agent in certain adhesive formulations. When combined with materials like polyvinyl alcohol (PVA) or starch, borax can facilitate cross-linking reactions that improve the cohesion and strength of the adhesive bond.

2. Viscosity Modifier: Borax can function as a viscosity modifier in adhesive formulations. By adjusting the concentration of borax, adhesive manufacturers can control the thickness and flow properties of the adhesive, making it easier to apply and ensuring proper coverage.

3. PH Buffer: Borax decahydrate can help to stabilize the pH of adhesive solutions. This is particularly useful in water-based adhesives where maintaining the appropriate pH level is crucial for the adhesive's performance and stability over time.

4. Enhanced Adhesion: Borax can improve the adhesion properties of certain adhesives, especially in formulations that require bonding to porous or uneven surfaces. The presence of borax can enhance the wetting and penetration of the adhesive into substrates, leading to stronger adhesion.
