Description

This product is prepared for application by the multi-stream flow method. The product in the multi-stream application apparatus does not change its viscosity for 24 hours. When applied to a wooden substrate, coatings with a thickness of about 30 microns are obtained, which dry in a convection tunnel dryer at 65 ° C in 30 minutes. The resulting coatings do not have stains, are even and smooth. Using the same hardener in of less or more than 8 parts by weight or a hydrochloric acid hardener in any amount, you get a product that is not stable for 24 hours, or in the case of a hardener based on methyl trichlorosilane in an amount of less than 8 parts by weight, the coatings dry 70464 in longer than required drying conditions Add these hardeners (up to 8 parts by weight of methyl trichlorosilane) directly to the basic assembly, without prior dilution, the product crosslinks much faster and is not suitable for use.

Claims (1)

1. Patent claim. characterized in that 8 parts by weight of methyltrichlorosilane, most preferably in the form of 15, are added to the base component of the pre-diluted mixture of organic solvents, most preferably a mixture of xylene and butanol in a weight ratio of 8: 2, to a viscosity of 50 ± 5 seconds. A 2% solution in xylene and then, without interrupting the stirring, the product is diluted to a viscosity of 25 to 30 seconds with organic solvents, most preferably the mixture of xylene and butanol mentioned.
