Features Of Solvay SILPUT Adhesive

  1. High-performance silicone-based adhesive offering excellent adhesion to challenging substrates including glass, aluminum, stainless steel, and painted surfaces.

  2. Outstanding resistance to UV radiation, thermal cycling (-40 °C to +150 °C), and long-term weathering without cracking or embrittlement.

  3. Low modulus formulation provides superior flexibility and stress relief in dynamic joints and expansion gaps.

  4. Neutral-cure chemistry — acetoxy-free — ensuring no corrosive by-products and safe use on sensitive metals and electronics.

  5. Good tooling time (30–45 minutes) and skin-over within 20–30 minutes under standard conditions (23 °C / 50% RH).

Typical Applications Of Solvay SILPUT Adhesive

  1. Structural glazing and façade bonding in commercial curtain wall systems.

  2. Sealing and bonding of insulating glass units (IGUs) and spandrel panels.

  3. Automotive lighting assembly, including headlamp and taillamp encapsulation.

  4. Electronics housing assembly requiring EMI-shield-compatible, low-outgassing adhesion.

  5. Industrial equipment enclosures exposed to outdoor environments and temperature extremes.
