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。

ELASTOSIL® NT 76 is a general purpose silicone rubber for textile coating applications, like manufacturing of conveyor belts, electrical sleevings, protective clothing, bellow expansion joints, awnings, sunblinds, sports performance fabrics, airbags and medical fabrics.

Due to the low viscosity and the non-thixotropic rheology ELASTOSIL® NT 76 is especially suited for fine coatings. It can also be used to dilute other liquid silicone rubbers to adjust coating viscosity. 

ELASTOSIL® NT 76 is processed by thorough incorporation of a crosslinker.

 

Recommended ratio is 100 parts of ELASTOSIL® NT 76 plus 

 

- 3 parts of CROSSLINKER 525

 

Pot life at 23°C: 2-3 days

 

Recommended curing conditions: 3 min at 150°C or 1 min at 180°C

 

Adhesion of ELASTOSIL® NT 76 depends on substrate and can be varied by crosslinker type/amount and additives (e.g. CATALYST C05 or adhesion promoters). Preliminary testing should be carried out to determine optimum formulation and cure conditions.

包装

This product is available in 20 kg pails and 200 kg drums. 

储存

Once opened, containers should always be resealed after use to prevent the platinum catalyst from being poisoned by amines, sulphur or phosphorus compounds.

 

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.
