Divalent acid ester (DBE) is a A high boiling point mixed solvent that can be used as additives and diluents. DBE has the advantages of strong dissolution, good leveling, low cost, easy handling, and relative environmental protection. Therefore, it is widely used in coating applications and has promoted the coating industry. Below, chemical solvent manufacturer Xuehang New Materials will introduce to you the product characteristics of DBE.
The characteristics of DBE can be summarized into the following five points: 1. Colorless and light fragrance, low toxicity and low cost, environmentally friendly, etc.; 2. Volatility accelerates as the temperature rises, especially suitable for industrial coatings; 3. It can dissolve a variety of resins and is miscible with most organic solvents; 4. It can improve the leveling, gloss, flexibility and adhesion of paints, increase pigment hiding power, reduce pinholes, and eliminate white fog; 5. Comparison It is environmentally friendly, non-toxic, biodegradable, can be burned cleanly, and has a high combustion value.
Volatile properties:
At room temperature , the volatilization of DBE is relatively slow, but can accelerate as the temperature increases. It is this characteristic that can effectively control the drying process of the coating film. In the early stage of drying, the temperature should be lower, and the solvent in the coating film should not evaporate too fast in order to form a good coating; in the later stage of drying, the temperature should be higher. , the remaining solvent is required to evaporate faster. This characteristic of DBE can eliminate problems such as fogging and pinholes in coatings
Solubility characteristics:
Bivalent Acid esters can also dissolve epoxy resin, acrylic resin, polyester resin, alkyd resin, polyurethane and vinyl resin. DBE or its mixed solvent can replace isophorone, ethylene glycol monoethyl ether acetate, etc. in conventional coatings. Ethylene glycol monobutyl ether acid ester, ethylene glycol monobutyl ether, etc.
Non-toxic:
Divalent acid esters and their mixed solvents can replace methylene chloride used in industrial paint removal. Due to the high toxicity of methylene chloride, many manufacturers are currently developing new paint stripper products based on DBE series products.
