Silane coating is used crosslinking agent
There are two ways to introduce these silane into the primer: 1) the metal components are dispersed to silane hydrolysis products, and the resulting pulp or paste is dispersed into the resin. 2) first disperse the metal particles into the silane hydrolysate/resin mixture and then disperse the silane water solution into the resin. In both methods, silane must be sufficiently hydrolyzed and silane crosslinking is sufficient.
And we observed that in each of these approaches, the final formula has a hydrogen dehydrogenation. Generally, in the hydrolysate/metal dispersion method, CoatOSil * MP 200 silane hydrolysate of hydrogen evolution than reference solution (without adding silane) and lquest * A - 187 silane hydrogen evolution amount is much less obviously. In particular, high ESO additions produced better results, but the condensation reactions did not improve significantly.
In the water solution/resin dispersion method, the effect was obvious, and the amount of the two silane additives was reduced to 2mL after 7 days. In addition, the amount of silane needed is less than the hydrolysate/metal dispersion process, which also reduces the amount of hydrogen dissociated in the formula.
The comparison of ESO CoatOSil * MP 200 silane indicates that the dispersion of the hydrolysate/binder is significantly less than that of the hydrolysate/metal dispersion process. Also need to be aware of is the ESO CoatOSil * MP 200 silane hydrolyzate/resin dispersion method of storage time in more than six months, and scattered Silquest * A - 187 silane product storage time is about 1 week.
This recipe shows excellent gloss and the overall print quality, reflects the ESO in metallic pigment coating and dispersion ability, while maintaining the refractive index of aluminum powder. The stability of the metal particles treated by ESO is suitable for the application of metal effect and anti-corrosion function.
ESO can also be used in water-based rich zinc coating or pre-coated zinc powder and zinc powder and aluminum powder. Monomer epoxy silane is widely used in many industries for anti-corrosive coating. We can expect ESO to be a new alternative to this high-demand industry with significant advantages in terms of potential efficiency and VOC reduction.
This paper introduces a new type of functional epoxy silane, which has great potential in many areas of coating industry. These products based on the low poly structure of epoxy silane, as compared with the conventional single silane oligomer (epoxy siloxane) usually have low alkoxy content and high epoxy functional groups.
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.
The experiment shows that these characteristics greatly reduce the release of the material and improve the crosslinking efficiency of the matrix resin. At the same time, because the material is 100% active substances, it is necessary to reduce the same amount of activity level, only as adding additives or as hydrolysate join the water-based formula.
ESO CoatOSil * MP 200 silane technical representative of products used as rich metal coating and primer formula additive amount of hydrogen evolution have improved, as a water-based acrylic emulsion coating formulation of the fouling resistance have obvious improvement. These epoxy silane oligomer as emerging technology platform to solve the challenge for the industry, produce better quality products, help to save cost, even further reduce the impact on the environment.
Coating for viscous liquid or powder material commonly, can use different construction technology of coating and surface, after dry can form adhesion strong, has a certain strength, continuous solid state thin film, gives the coated to protect and beautify and other desired effect.
The coating is composed of three components, mainly film, secondary and auxiliary.
(1) the main forming material. It contains oil and resins, which are the main factors that determine the membrane properties of film, which can be made into film, or can be glued to the pigment, etc., and also called base material.
(2) the secondary membrane material. It contains paints, fillings, and toughening agents.
(3) auxiliary membranes. It contains various solvents and additives. The auxiliary film-forming material can not be a film alone, but it can help the coating process or coating. The solvent (or water) is the viscosity and solid content of the paint.
