Application of adhesion promoter LD9051

2021-11-23   Pageview:456

Adhesion promoter LD9051 is widely used in plastic, metal and glass substrates, such as UV light curing vacuum coating top coat, UV ink for metal substrates, UV adhesives for glass and metal, etc.

It can also be used for the stabilization of acrylic emulsions and other acrylic systems, epoxy, polyurethane, nitro and other material blending modifications to improve the surface adhesion, adhesive strength, stability and chemical resistance of materials have significant effects.













Dicyandiamide Dicyandiamide, also known as dicyandiamide, has a simple structural formula Cz HNs. Relative molecular mass is 84. Dicyandiamide is a rhombohedral crystal of monoclinic system, paraffin emulsion use with a nitrogen content of 66.7%, a relative density of 1.40, and a melting point of 207~209°C. Slightly soluble in cold water, soluble in hot water, ethanol and acetone, but hardly soluble in ether, benzene and chloroform. Dicyandiamide is mainly used as a foaming agent and flame retardant in fireproof coatings.

Ammonium Chloride Ammonium chloride is white powder or crystalline particles, molecular formula NH gCI, relative molecular weight 53.49, easy to deliquesce, easy to dissolve in water, and the aqueous solution is slightly acidic. It reacts with alkali to release ammonia gas, and reacts with formaldehyde to generate hydrochloric acid.

Ammonium chloride is mainly used as a foaming agent and a flame retardant in fire-resistant coatings, and sometimes also acts as a catalyst and curing agent. Ammonia aqueous solution of ammonia is called ammonia water, molecular formula NH, OH, relative molecular weight 35.045, colorless or A slightly yellow transparent liquid. Under normal conditions, the gas ammonia separated from the ammonia water has a strong irritating odor, is toxic, and has the risk of combustion and explosion. The explosion limit of ammonia is 15%-28% (volume fraction). The maximum allowable concentration in the air is 30mg/m. Ammonia can suffocate people, irritate the eyes, and burn the skin. Therefore, you must be very careful when using ammonia and wear protective equipment. Ammonia water should be stored in a closed container and stored in a cool, windy, and isolated place from fire.
Industrial ammonia is an aqueous solution containing 25% to 28% of ammonia. It is a weak inorganic base. It is mainly used as a foaming agent in fireproof coatings.

Ammonium bicarbonate Ammonium bicarbonate is a white powdery crystal, molecular formula NH: H COs, relative molecular mass 79.06, with ammonia odor, used in fire-resistant coatings mainly as a foaming agent, acid source, flame retardant.
