Hybrid Construction Sealants

Combine the best properties of silicone and urethane sealants in one package.By fusing silicone and urethane sealant chemistries, the strengths of each provide unique solutions and improved application. Hybrid sealants are inherently low in VOC and odor. This results in a user-friendly, high-performance product.

Hybrid sealants offer several other important advantages – color stability, paintability, reduced shrinkage, moisture tolerance, minimal dirt pick-up, and exceptional adhesion to most construction materials.

Plus, the addition of our new Dynatrol I-XL Field Tintable Hybrid allows for unlimited color options in the field. This field-tintable hybrid sealant utilizes our Universal Color Packs. Save time and materials by mixing the perfect color for your project on-site. 

Traditional sealant chemistries have remained unchanged for the last few decades. Take versatility a step further- choose performance, sustainability and adaptability with Pecora Hybrid Sealants.


Silicone Construction Sealants

Maximize jobsite flexibility and structural protection while minimizing costs with Pecora’s innovative line of silicone sealants solutions. Our silicone construction sealants are designed to eliminate the staining of porous substrates, reduce the need to repair or remove aged and failing sealant, and to reduce the cost of wasted product on the jobsite.

Some of Pecora’s innovations in high-performance silicone construction sealant solutions include:

  • Unprecedented Flexibility with 890FTS and 890FTS-TXTR Silicone Sealants – high-quality, non-staining silicones that can be quickly and easily tinted at the jobsite. Pecora’s 890 Field Tintable Silicone line is the industry’s first to include a textured option. Perfect for historic restoration where stone and grout have previously been utilized. Used in conjunction with our Universal Color Packs, you have 51 standard color options to choose from. Custom color packs provide you with the flexibility of virtually any color your specific project requires. Pecora’s 890FTS and 890FTS TXTR eliminate waste and reduce your overall jobsite costs by allowing you to select your amount, select your color and select your appearance.
  • NST Non-Staining Technology™ Don’t Stain Your Reputation® offering the industry’s first complete line of non-staining silicones. We have removed the free fluids that are commonly associated with substrate staining as well as the residue rundown often seen on glass and metal panels. By removing the possibility of fluid migration Pecora has virtually eliminated the possibility of staining and residue rundown. NST silicones also provide the additional benefits of increased adhesion and reduced dirt pick up as compared to traditional silicones. Click here to download a sample NST 20-year warranty
  • Sil-Span preformed profiles are an alternative to the costly removal of aged, failed sealant or costly substrate repair. Sil-Span allows you to simply bridge over the joint or glazing detail with a pre-formed low modulus profile that can be textured and colored to match your substrate.
