Pecora 1215 Seam Sealer Advantages
- Rapid through cure
- VOC compliant and mild odor
- Superior adhesion: Will bond tenaciously to most substrates without the need for priming.
- Adheres extremely well to glass fiber reinforced polyamide composite structured thermal barriers.
- Excellent weatherability and color stability: Because of its 100% silicone composition, it is virtually unaffected by UV, ozone, and temperature extremes.
- Resilient: Will remain flexible under extreme temperature swings (-60°F to 300°F)
- Compatible with polymeric thermal break systems
- Black light sensitive for accurate in process Quality Control checks (available in Tru-White and Translucent).
- Fast cure
- High Solids
- Easily adapted to existing processes currently utilizing traditional high VOC sealant materials.
- Will not harm plastics such as polycarbonate or acrylic.
- Compatible with acrylic and polycarbonate based security glazing materials (Lexan® and Plexiglas®).
- In-shop fabrication of windows and doors for narrow corner joints and seams
- Fastener heads and rivet seams
- Butt joint seams
Pecora 1215 Seam Sealer should not be used in the following applications:
- Sealing submerged joints or below the waterline in marine uses.
- In designs that will be painted after application of the sealant. Sealant should be applied after painting is completed.
- In expansion and control joints
Surface Preparation: Clean all joints and glazing areas by removing foreign matter and contaminants such as oil, dust, grease, frost, water, surface dirt, old sealants or glazing compounds and any protective coating. Metal, glass and plastic surfaces should be cleaned by solvent procedure or by mechanical means. Soap or detergent and water cleaning treatments are not recommended. Cleaning of all surfaces should be done on the same day on which the sealant is applied.
Priming: Pecora 1215 Seam Sealer does not require priming on most common substrates. However, Pecora strongly suggests adhesion pre-testing, either in the field or in Pecora’s laboratory, particularly on special coatings or surface treatments which may impair optimum adhesion. Where primer is indicated, P-120 should be used on special metal and plastic surfaces. Pecora routinely conducts project specific adhesion, compatibility, and staining tests in its laboratory on representative substrate samples.
Application: Do not open 1215 until ready for use. 1215 is sensitive to humidity. Replace lid or Plews gun pin when not in use. Application by cartridge or Plews gun is recommended. When appropriate, mask areas to be protected from overfill and tooling. Remove masking tape while sealant is still uncured. Avoid air entrapment during application and tooling.
Cleaning: Excess sealant should be removed from all surfaces while still uncured using Iso-propyl Alcohol or Windex. Cured sealant is very difficult to remove without altering or damaging the surface it is adhered to. Refer to solvent manufacturer’s Material Safety Data Sheet.
Shelf Life: Twelve months from manufacture in original, unopened containers when stored at temperatures below 80°F (27°C).
Contact with uncured sealant, with vapors generated during curing, or with dust formed from cured sealant may cause eye, skin, or respiratory tract irritation and possible allergic reaction. Use only with adequate ventilation or wear an appropriate NIOSH-approved respirator. Avoid contact and wash thoroughly after handling. May be harmful if swallowed. Keep away from heat, sparks and flame. Refer to Material Safety Data Sheet (MSDS) for more information.
