Methyl acrylic acid reduced glycerol coating crosslinking agent
GMA300 methacrylic acid - methyl acrylic acid - methyl acrylate polymer.
Methyl acrylic acid glycolate (GMA) crosslinking agent resin mainly refers to the following monomers as the main functional units.This is an appropriate substitute for TGIC.
Compared with AralditePT910, methyl methacrylate (GMA) crosslinking agent does not need to be specially designed for polyester, which can be used as a regular polyester designed for TGIC, which is best suited for polyester with acid value of 22-26mgkoh/g.
The GMA crosslinking agent has a much faster crosslinking speed than TGIC, which causes the viscosity to rise rapidly and causes the problem of flow squared.In addition, GMA resin is easy to be separated from the polyester resin in the formula, which means that the compatibility is poor, which leads to the deterioration of the wet performance of the pigments to make the coating susceptible to hair flowers;The mechanical properties of the dispersion are also poor if they cannot be effectively improved.In other conditions, the system will be contaminated with the existing paint system.
Compared with the TGIC system, GMA300 has about 300 epoxy equivalent, which requires high dosage of GMA resin as crosslinking agent, which is generally 16/84 weight and therefore is not economical.The coating with GMA300 crosslinking agent is equivalent to TGlC powder in outdoor durability.However, the coating hardness is lower than the TGIC system.
Methyl methacrylate is a chemical substance that is C7H10O3.

Since the GMA molecules have active vinyl and an ionic reaction, the two groups can be polymerized in a functional group and can be polymerized in an ion reaction mode.
So, can be used in ethylene polymer type and condensation polymer modification, GMA can step in polymerization in three ways, one is the ethylene polymerization, the epoxy group on the branched chain, namely "O" type polymer;The second is the epoxy-open loop, which enables the vinyl to be located on the branch chain, which is the "V" type polymer;The third is a compound with active hydrogen and GMA reaction, which is a chain on the epoxy base.Using any of these three methods, the polymer will be modified when polymerized.In terms of coating, because of the addition of GMA, can improve the coating hardness, gloss, adhesion and weather resistance, etc., can be used in acrylic paint, acrylic paint, alkyd resin coating, vinyl chloride resin as well as some water-based paint.
For adhesives and non-woven fabrics, it can improve the adhesion of metal, glass, cement, polyfluoroethylene and other adhesives.The non-woven fabric used for the synthesis of latex can improve its resistance to washing without affecting the sense of touch.When used in the processing of synthetic resin materials, it can improve the injection molding, extrusion molding, and obviously improve the adhesion of resin and metal.Used for synthetic fiber, it can improve its shading force and color fastness, improve the anti-wrinkle and anti-shrinkage ability.This product can improve the sensitivity, resolution and corrosion resistance of photoreceptors.
Methyl methacrylate with alkali metal hydroxide in low molecular and high boiling point solvents, reaction in the presence of inhibitor, generated (meth) acrylic acid alkali metal salt, dry to remove volatiles, such as water and low molecular alcohol to join epichlorohydrin (ECH) and phase transfer catalyst, esterification reaction, get the crude ester containing glycidyl ester of acrylic (methyl) products.
Methyl methacrylate is the reaction of methyl methacrylate and epichlorohydrin.Raw material consumption quota: methacrylate 780kg/t, epoxy chloropropane 690kg/t, sodium hydroxide 330kg /.It can also be obtained through the exchange reaction of methyl methacrylate and epoxypropyl alcohol.Among them, the former method is easy to use and mild reaction, which is widely used and method in the world.
