10oz Marine Caulk Cartridge, Black – SIS440 Teakdecking Systems

• HIGH QUALITY MARINE POLYMER || 10oz cartridge of black caulk – One-part silane polymer – Forms a solid rubber compound with highest rated UV resistance – Excellent resistance to chemicals – Superior temperature stability – Easy to sand – Improves project turnover time 
• FLEXIBLE & PRIMER-FREE || Thixotropic paste which does not drip or sag – Easy to work because it stays flexible – One-step process saves application time – No solvents – Environmentally friendly – Safe for work environment – More economical – Less waste 
• FIRST-CLASS APPEARANCE || Use in seams from 3 to 10mm wide to achieve first-class appearance – Seam depth should be equal to or greater than the seam width – Caulk must fill to bottom of seam – Bond-breaker tape recommended for seams of 5mm (3/16”) or deeper – Full depth caulk seams extend teak deck life
• CURE TIME || Cures to provide better adhesion, longevity and appearance as compared to polysulfide, polyurethane and MS polymers – Black caulk is ready for sanding after a minimum of 48 hours at 68°F (20°C) – This is based on seams ¼”x¼” (6.4mmx6.4mm), larger seams may require additional time 
• PROPERTIES || Available in white and gray – Product has 18-month shelf life from date of manufacture (printed on bottle) – Meets Federal Specifications & ASTM C920 – Manufactured in an ISO 9001 facility  

SIS440 Caulk is the proven leader in the marine industry and was developed specifically for teak deck seams. It is a one-part, paste-like neutral cure formulation and when exposed to moisture in the air, it reacts to form a tough, flexible solid rubber compound. The sealant does not sag during cure, and has excellent temperature stability and chemical resistance once cured. Because the sealant is neutral cure, it is non-corrosive to all substrates, will not damage the surrounding environment or structures, and provides minimum shrinkage. Caulk is easy to sand and will not clog sandpaper.

Store in a dry area at temperatures above 32°F (0°C) and below 80°F (26°C). Do not expose to direct sunlight, extreme heat, or freezing. The sealant has a shelf life of 18 months from manufacture date. See “BEST USED BY” date on packaging. Not designed for use under the waterline.

Other Applications:
– Bedding deck equipment/hardware
– Bedding parts (steps, pads, etc.)
– Caulk seams in other wood decks
– Edges around sealed windows
– Construction
