GENIOSIL® SMP 100

GENIOSIL® SMP 100 is a clear, viscous liquid.



特性

GENIOSIL® SMP 100 with release of methanol results in a high crosslinking density, thus producing scratch-resistant coatings. The high number of trimethoxysilyl crosslinking groups in the molecule is crucial here.
GENIOSIL® SMP 100 is a silane-terminated polyester with 3-trimethoxysilylpropylcarbamate end groups. GENIOSIL® SMP 100 reacts with moisture (releasing methanol) to form silanols, which can react further to produce stable siloxane compounds.

免责声明

所提供之所有信息均基于我们当前所掌握的知识。尽管如此,我们不对其作任何担保、也不承担任何责任,并且保留在任何时候进行技术变更的权利。购买方应在预测试中对所提供之信息以及产品在既定应用中的适应性进行检查。任何时候都必须以合同条款与条件为准。此外,本免责申明还适用于与第三方权利有关之事宜,尤其是在德国境外。


GENIOSIL® SMP 100 dissolves readily in standard organic solvents. It is virtually insoluble in aqueous media, and reacts slowly releasing methanol and forming a resinous deposit.


Despite its highly reactive end groups, GENIOSIL® SMP 100 is stable in air for several days in the absence of a catalyst. However, its reactivity toward water and atmospheric humidity must be taken into account during storage and processing, since the material will otherwise undergo slow condensation. Therefore, the material should only be removed from its container in the absence of moisture (e.g. inert gases).


GENIOSIL® SMP 100 can be formulated by conventional methods and mixing procedures. The composition can be varied to produce the required properties in the resultant coating.


Water scavengers are needed to stabilize formulations against premature curing during preparation or due to the presence of moisture during storage. GENIOSIL® XL 63 (trimethoxysilylmethyl-O-methyl-carbamate) and GENIOSIL® XL 10 (vinyltrimethoxysilane) are particularly suitable scavengers.


Suitable catalysts include strongly basic amino compounds (e.g. DBU, DBN) as well as organic and inorganic acids (e.g. phosphoric acid derivatives). Common organometallic compounds can also be used.


Clearcoat Base Formulation:


100 parts GENIOSIL® SMP 100

1 part water scavenger (e.g. GENIOSIL® XL 63)

0.1 parts silicone-based flow enhancer

5 parts catalyst (butylphosphate, 10% in methoxypropylacetate)

1 space line


Solids content and viscosity can optionally be adjusted by using a solvent (e.g. methoxypropylacetate). The formulation can be further adjusted with rheological agents, pigments and other common surface-coating additives.


GENIOSIL® SMP 100 is used as a reactive binder for scratch- and chemical-resistant coatings. Curing takes place in the presence of water or atmospheric moisture.

储存

The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
