Description
PSI 0300 is a long chain alkyl trimethoxysilane. When applied to concrete, brick or stone built items; PSI 0300 will permeate through the pores of the material and form a thin, transparent layer that acts as a protective film. This film is air permeable but hydrophobic and so provides excellent protection against corrosion caused by moisture and any salts that may be moisture carried.

Technical Data

Chemical Content:	Long-chain Alkyl-trimethoxysilane
Appearance:	Colourless, transparent liquid
pH Value:	7

Applications
Should be prepared as a mixture of PSI 0300 and ethanol on a 1:10 ratio. A small quantity of PC1100 can be added to provide stability for the mixture if required for storage. PSI 0300 can be applied by dipping, spraying or brushing. PSI 0300 should be applied in three separate coats to provide maximum surface protection.
