Epoxy silane crosslinking agent class coatings

Epoxy silane crosslinking agent class coatings, mainly is suitable for the containing carboxyl, amino, hydroxyl aqueous system, the reaction mechanism is the epoxy group in the crosslinking agent and water-based resin hydrophilic group carboxyl, amino, hydroxyl in response; Alkoxy hydrolysis condensation reaction with water to form silica key, thus greatly improve the coating to the substrate adhesion and water resistance.

Epoxy silane crosslinking agent class coating is mostly environmental non-toxic, especially it's amazing to join epoxy silane crosslinking agent class coating of water-based system applicable period abnormal long, room temperature can reach a year, so you can make the stable single-component coating. Attention! If you want to make the film fast curing, can be used together with the catalyst or heating.
Outside the class type: epoxy silane view: colorless transparent liquid than weight: 1 molecular weight: 288.46 refractive index: flash point 1.45: boiling point: 104 > 300 active ingredients: 100%

Mixer bicomponent when using water can be directly added to the system. Instead of isocyanate, n propyl organism and amine crosslinking agent.

In pieces when one component is used to adjust PH value to the water system between 6 ~ 8, this is conducive to long-term preservation.

Pieces of this product general amount for the resin to adjust the solid content of 0.5% ~ 0.5%, special requirements can be more appropriate.

When using this product, such as difficult to disperse phase solvent can be used after some nonionic emulsifier to emulsify added.
Inside the metal coating suggest adding amount is 1% of the solid content in leather coating added amount for the solid content of 2%, in the plastic coating inside suggest adding amount is 2% of the solids inside the glass coating added amount for the solid content of 1.5%, in architectural coatings add amount of solid content of 0.5% ~ 0.5%

In general advice in waterborne wood coatings additives for the solid content of 2%, floor coating can be added to 3% in textile coating added amount for solid content is 1%, for special wash water requirements can be added to 3%

Epoxy silane crosslinking agent is a kind of colorless transparent liquid, mainly used in unsaturated polyester composite materials, can improve the mechanical properties of composite materials, electrical properties, pervious to light performance, especially in the wet performance of composite material can be greatly improved.

Use (including the coupling agent) infiltration processing glass fiber, glass fiber reinforced composites can be improved mechanical strength and electrical properties of wet. Wire and cable industry, with the coupling agent treatment clay filling peroxide crosslinked EPDM system, improving the cost factor and inductance capacitive reactance. With vinyl acetate and acrylic acid or methyl acrylate monomer copolymerization, the polymers are widely used in coatings, adhesives and sealants, provide excellent bonding strength and durability.

Crosslinking is a generic technology, can undertake research as a research method, is used to improve the mechanical properties, solvent resistance and interface link, and used for curing liquid polymer or hardening of the polymer surface.

Some study of the crosslinking of supramolecular is still at the stage, but is considered very promising. , there appeared, but also will have many applications for higher mechanical properties, solvent resistance, interfacial bonding, as well as the solidification of liquid polymer or hardening of the material surface, etc.

Macromolecular crosslinking to form an independent more resilient and three-dimensional structure more reasonable, usually with sulfide and oxide in chemical reaction, but also can use other methods. Heating in general can speed up the reaction. In addition to these technologies, there are many special routes, some of which have been used in industrial production, other some rarely used or limited in the experimental stage.

A water-based nanometer zinc rich epoxy silane coating, with two components, its formula is characterized by: with all components is 100%, the weight of the following for each component weight ratio: A component: 800 ~ 1000 mesh nanometer zinc powder 65% ~ 80%, the emulsion type epoxy resin 8% ~ 25%, 0.1% ~ 5% ethanol, deionization water 0.5% ~ 5%, thickener 0.1% ~ 1%, the heavy dose of 0.1% ~ 3%; B component: silane portfolio: [double a silicon alkyl amino silane, vinyl silane] 1.5% ~ 5%, and the combination of these two kinds of silane distribution ratio between 0.15 ~ 0.30, and 3% ~ 8% curing agent.
