Bostik V70 Architectural Grade Silicone

Product Information

Bostik V70 is a high performance architectural grade structural glazing silicone. One-component, non-flowing, neutral cure, high modulus sealant. It cures by absorption of atmospheric moisture to form a flexible and durable elastomeric sealant.

  • Bostik V70 silicone sealant meets the currently accepted engineering standards for structural glazing
  • This high strength silicone sealant has very good unprimed adhesion properties, to a broad range of building substrates.* (Substrate testing must always be carried out first)
  • These features make this product a very good reliable structural adhesive sealant for both the Construction and Industrial industries
  • The thixotropic nature of this product ensures that it will not slump in typical construction joints
  • Excellent UV stability
  • Long-life reliability
  • Maintains its elastomeric structural joint sealant properties permanently, even under harsh conditions and temperature extremes
