The curing temperature of the curing agentand the heat resistance of the cured product has a great relationship.Similarly, in the same type of curing agent, although the same functionalgroups, but due to different chemical structure, its properties and curingproperties are different. Therefore, a comprehensive understanding of the samefunctional groups and different chemical structure of the polyamine curingagent of the traits, characteristics, the choice of curing agent is veryimportant.In term ...

The silicone polymer is a polymer compoundhaving a silicon atom in its main chain. At present the most importantorganosilicon polymer is polysiloxane. Polysiloxanes are polymeric, chain-like,cyclic or reticular polymeric compounds that are polymerized from many monomerscontaining double bonds, commonly known as silicones. Its structure ischaracterized by containing a silicon, oxygen atoms alternately arranged in thebasic skeleton, each silicon atoms are connected with organic groups. Thesilicon- ...

Silicone is a very good nature of thepolymer material, with good temperature resistance, weatherability,physiological inertia and insulation properties. Electronics, biomedical,aerospace, machinery, shipbuilding and daily-use industries have a wide rangeof applications. Silicone materials from the morphology of a gaseous, solid,liquid, etc., can be cross-linked into a solid membrane. Can also be a softelastomer, can be room temperature crosslinking, high temperature crosslinkingcan also be appli ...

Polyacrylic acid sodium is a matureindustrial products, there are industry standards. The standard number is: HG /T2838-2010. Standard product appearance is colorless to yellow liquid, solidcontent greater than or equal to 30%.High relative molecular mass forflocculants.Water treatment agent - flocculantPolyacrylic acid sodium is a linear,soluble polymer compounds, the molecular chain of the carboxyl group due toelectrostatic repulsion. So that the polymer chain stretches around, causingthe adso ...

With the rapid development of the nationaleconomy, the necessity of water treatment is increasingly prominent,flocculation technology is to improve water treatment efficiency of the mostcommonly used technology. Especially as the flocculant high molecular weightpolyacrylic acid sodium, has become the subject of domestic and foreignresearchers competing research. In this paper, the emulsion polymerization ofacrylic acid and its comonomer is studied. The choice of emulsifier, the choiceof initiato ...

Health HazardsInhalation, ingestion of the eye andrespiratory mucosa have a strong stimulating effect. High concentrations, cancause corneal opacity, respiratory inflammation, and even pulmonary edema, andmay be associated with dizziness, headache, fatigue, nausea, vomiting,palpitation and other symptoms. Splashed on the skin, can cause necrosis,ulcers, long-term unhealed.First-aidSkin contact: Immediately removecontaminated clothing, mobile water rinse for more than 15 minutes. If burns,medical ...

Silane SiH4 in the hydrogen atoms arereplaced by chlorine atoms, the total known as chlorosilane, low chlorinecontent when the gas, the higher the liquid, colorless or yellow, N = 0, 1, 2,3;Chlorosilane with active hydrogen compoundswith a fierce reaction, such as water, alcohols, phenols, silanol, organicacids, etc., release hydrogen chloride.With the organometallic compounds, chlorineatoms are replaced by the corresponding organic groups to generateorganochlorosilane or organosilane.The silico ...

Epoxy silane crosslinking agent is acolorless transparent liquid, mainly used in unsaturated polyester composites.Can improve the mechanical properties of composite materials, electricalproperties, light transmission properties, in particular, can significantlyimprove the wet properties of composite materials.The main purpose:Mainly used in unsaturated polyestercomposites, can improve the mechanical properties of composite materials,electrical properties, light transmission properties, in partic ...

The isobutyl functional group-containingcoupling agent: isobutyltriethoxysilane, silane coupling agentThis product is high purity isobutyltriethoxysilane, small molecular structure can penetrate cementation surface, penetrateinto the concrete and exposed to acid or alkaline environment in the air andwater molecules in the base chemical reaction, Forming a water repellenttreatment layer, thereby suppressing the ingress of water into the substrate.Resulting in waterproof, anti-Cl, anti-ultraviolet ...

Can improve their bonding strength, waterresistance, weather resistance and other properties. Silane coupling agents canoften solve the problem of some materials can’t be bonded for a long time.Silane coupling agent as the principle of the role of tackifier itself has twogroups; A group may be bonded to the bonded framework material; While the othergroup can be combined with high molecular materials or adhesives, resulting inbonding interface to form a strong chemical bond, greatly improving th ...
