The polyurethane resin coating crosslinking agent
Polyurethane paint, or polyurethane paint, is a coating that contains a significant amount of aminoester keys in its coating.
Oil modified polyurethane paint. Storage stability, the coating is dry and fast, it has good abrasion resistance, alkali resistance, oil and solvent, but it is not suitable for outdoor use.
Chaoqi crosslinking type. It has the performance of fast drying, good adhesion, wear-resisting, waterproof, moisture-proof, acid and alkali resistance. It can be used as an anticorrosion coating and cement coating for underground works.
Closed type polyurethane paint (hot baking type). It has the properties of stable storage, low toxicity, oil resistant, solvent, acid and alkali resistance, and it also has electrical insulation and heat resistance and cold resistance. It is commonly used in metal anti-corrosion coatings.
Bi-component hydroxy crosslinked polyurethane paint. It can be dry at room temperature, with low toxicity, strong paint film, high gloss, good adhesion, corrosion resistance, oil resistance and good water resistance. Applicable for coating of metal, cement, wood and rubber, leather etc.
Catalytic crosslinked polyurethane paint. The coating has good resistance to oil, water, acid and alkali, resistance to organic solvents, and has excellent adhesion and wear-resisting properties. Generally used for surface coatings such as wood and concrete (such as wooden floor paint)
Polyurethane paint is compared to other coatings, and has some special properties:
The paint film is hard and hard to wear;
Excellent chemical resistance;
Good oil and solvent resistance;
The paint film is bright and full;
Good heat resistance and adhesion.
Construction on wet surfaces;
7. Take advantage of the free isocyanate resin base of alkyd resin, phenolic resin, coal tar, dilute acid resin modified, etc. Can be made a variety of excellent performance of coatings.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:
The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.
Disadvantage is that the majority of polyurethane resin film exposure in the sun for a long time, quickly lost light, pulverization, yellowing, therefore should not be outdoor use, unfavorable also light color paint and decorative paint; Isocyanate is stimulative to the human body, partial polyurethane lacquer construction is more complicated, the demand is higher.
In paint construction, auxiliary material can assist the formation of lacquer film. Different auxiliary materials have different effects on the formation of lacquer film. In numerous auxiliary materials, catalysts, toughening agent, most of the former for oil-based paint widely used, the latter for the resin paint widely used, they are of great significance to the formation of the paint film.
Commonly used auxiliary materials have the drier, the enhancement agent.
It is commonly used for lead drier, cobalt drier, manganese drier, zinc drier, iron drier, calcium drier. The dosage of drier is not too much, the drying rate of lacquer film is not proportional to the dosage of the machine.
Agent: the non-volatile organic liquid in the paint film is called an additive agent, and it is also known as a toughener and a softener. It is used to increase the flexibility of the paint film and improve the adhesion of the paint film. The commonly used additives include vegetable oil, natural wax, foreign compound and polymeric compound.
Polyurethane is short for polyurethane, a polymer. Polyurethane is a new type of organic polymeric material known as "the fifth plastic" and is widely used in many fields because of its excellent performance.
