Functional epoxy silane crosslinking agent
2017-4-7 10:51:29
Functional epoxy silane crosslinking agent,The final formula has hydrogen evolution phenomenon. 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.
Specifically, the effect of the high amount of ESO add better, but no obviously improved condensation reaction. In hydrolysate/resin dispersion method, the effect is obvious, after 7 days both silane additive amount of hydrogen evolution to within 2 ml.
In addition, relative to the hydrolysate/metal dispersion process, needs less amount of silane, this also reduces the amount of hydrogen evolution in the formula. ESO CoatOSil * MP 200 silane contrast of the two methods shows that the hydrolysate/adhesive dispersion process than hydrolysate/metal dispersion has decreased sharply. 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 ideal for metal effect and corrosion function of application.
ESO can also be used for the bottom of the waterborne zinc rich coating or shop primer zinc powder dispersion and protective coating of zinc powder and aluminum powder. Monomer epoxy silane has been widely applied in industries of anticorrosion coating. We can foresee the ESO is a new kind of alternatives to the high demand of industry, the potential efficiency and reduced VOC has a great advantage.
In this paper, a new type of functional epoxy silane, in multiple areas of coating industry has great potential. 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. Experiment shows that these features greatly reduced the materials of the release quantity of VOC improved matrix resin crosslinking efficiency.
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.
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.
Especially in the plastic coating, alcohol solvent swelling on the surface of a plastic, only without softening plastic. In the production of Marine coatings and heavy anti-corrosion coatings enterprises use can dissolve more strong, relatively volatile rate is low (0. 44 - strong hydrogen bonding) of n-butyl alcohol as the main active solvent; Ester solvent at present is mainly used in the nitrocellulose coatings, such as in the nitro wood coatings, n-butyl acetate is widely used as reactive solvent.
Actually look from feature, ester solvent can be used in more types of coatings, such as the type acrylic resin (especially hydroxyl acrylic type) plastic coating is the main activity of the solvent selection more esters (ethyl acetate, n-butyl acetate). Esters of solvent polarity is lower than alcohol, but the polarity resin has very good solvency.
As ester in alcohol and acid radical groups in the growth of carbon chain, the polarity of the resin dissolved force will decline, but the solvent of low polarity resin can enhance instead. N-butyl acetate: for example, nitrocellulose, acrylic resin and alkyd resin has good solvency, it belongs to medium solvent volatilization rate, its volatility is high enough to quickly evaporate from the film, low enough to prevent shrinkage cavity, efflorescence and disorderly flow.
