Product Description
Product Description
SILIRESIN 430 S black is a solvent-free, two-component polyurethane-based casting resin system. The system consists of the resin component SILIRESIN 430 S black and the hardener SILIRESIN HARDENER 301.
Processing
SILIRESIN 430 S black is processed with SILIRESIN HARDENER 301 in the specified mixing ratio. Processing can be carried out manually, with a mixer, or with suitable two-component mixing and dosing systems.
The components must be stirred until homogeneous and thoroughly mixed before processing. Air inclusions should be avoided as much as possible.
