Dynasylan® SIVO 121 is a multifunctional, nearly VOC-free, water-borne silane system.
Scope of Application
Dynasylan® SIVO 121 - containing wood preservation agents can be painted, rolled or sprayed. In a spray application it is mandatory to minimize the generation of Aerosol emissions by suited procedures (e.g. application of HPLV spray processes, air driven low pressure spray processes. Consecutive application steps should be carried out wet-in-wet as a dried coat of Dynasylan® SIVO 121 will almost immediately exhibit a strong repelling effect. Consequently a second application step would therefore be much less effective.
Recommended dosage during application: For a full range effectiveness and durability (up to 1500 h of QUV-stability in transparent systems) 300 g/m² of undiluted Dynasylan® SIVO 121 are necessary. That amount can be applied by either one-step or multi-step procedures, depending on the absorptiveness of the wood substrate.
