(Tremco) Spectrem 3 Silicone Hybrid Neutral cure +/- 50% movement, low modulus for caulking window perimeters, stucco and expansion joints where high movement may be encountered. Spectrem 3 puts minimum stress on the bond line during movement.

  • Specifically formulated to seal porous and non-porous substrates, EIFS, metal panels, masonry and pre-cast concrete joints.
  • Low polar attraction to dirt makes buildings easier to clean and maintain.
  • Low-modulus and low Shore A hardness reduce chance of EIFS substrate failures when compared to applications with medium-modulus sealants.
  • Primerless adhesion to most porous substrates.
  • Extended tooling time and workability in high temperatures.
  • Ease of use reduces the risk of application failure.
  • Matte finish affords an aesthetically pleasing appearance with EIFS and stone substrates.
  • No cure inhibition with Spectrem 1, Spectrem 2, Dymonic® FC when applied “wet-to-wet,” minimizing the chance of leakage when sealants abut at glazing and other façade intersects.
  • Low-VOC and zero-solvent content satisfies the LEED Indoor
  • Greenguard Gold certification ensures safety for use in the most sensitive indoor environments including hospitals and schools.
