ELASTOSIL® A59 GRAY

ELASTOSIL® A59 GRAY is a self-levelling one-component, amine-cure formulation which cures at room temperature by reaction with air humidity to a flexible and durable silicone elastomer. It is particularly suited for screen printing on gaskets



Properties

  • amine-curing system
  • extended skin-over time
  • cure accleration by temperature, further strong activation by CO2 
  • no use of organotin catalysts
  • Recommended service temperature from -45 °C to +200 °C

Specific features of ELASTOSIL® A59 GRAY

  • Heat resistant
  • Low viscosity
  • Oil resistant
  • Self-levelling

Low viscous grade suitable as general purpose sealant for coating and potting, furthermore perfectly suited for screen printing applications for gaskets e.g cylinder head gaskets


ELASTOSIL® A59 GRAY is a one-part room temperature curing coating therefore the curing rate depends on temperature and on atmospheric humidity. The curing rate can be accelerated by heat exposure or exposure to carbon dioxide concentration above 1% p.b.v.


Uncured or partially cured silicone can be removed by help of organic solvents such as alipatic or aromatic hydrocarboncleaning should take place before the rubber is fully cured. Once completely cured, only mechanical removal supported by prior solvent swell is possible. Swelling can be accelerated by elevated temperature.

Detailed processing instructions are given in our brochure “ROOM TEMPERATURE VULCANIZING (RTV) SILICONES - MATERIAL AND PROCESSING GUIDELINES

We recommend running preliminary tests to optimize conditions for the particular application.

 

Storage

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.
