Ottoseal S51 plastic floor silicone transparent 310ml

Description

Ottoseal S51 for sealing on floor coverings such as rubber floors, linoleum floors, PVC floors, vinyl floors. Ottoseal S51 is flame-retardant.

  • 1K silicone sealant based on an aminoxime system - MEKO-free
  • Very good weather, ageing and UV resistance
  • Colour-matched to floor coverings made of PVC, rubber and linoleum
  • Flame-retardant

Areas of application:

  • Connection joints on rubber floors
  • Connection joints on linoleum floors
  • Connection joints on PVC floors
  • Stress-compensating sealing of identical and different materials such as glass, stainless steel, aluminium and some plastics

Substrates:

The bonding surfaces must be clean, free of grease, dry and sound so that the high-temperature adhesive adheres. The bonding surfaces must be cleaned and any contamination, such as release agents, preservatives, grease, oil, dust, water, old adhesives / sealants and other substances that impair adhesion, must be removed. Cleaning non-porous substrates: clean with OTTO Cleaner T (flash-off time approx. 1 minute) and a clean, lint-free cloth. Cleaning porous substrates: clean surfaces of loose particles mechanically, e.g. with a wire brush or a grinding disc

When jointing linoleum floor coverings, only wet the smoothing tool with a little smoothing agent or pull off dry. Remove smoothing agent residues from the covering before they dry on, to avoid staining.
