## Overview

TDS SIS440 is a premium 10oz black marine caulk cartridge engineered specifically for teak deck seams. This one-part silane polymer forms a flexible, UV and chemical-resistant rubber compound that cures in 48 hours, providing superior adhesion and a first-class finish. Its primer-free, drip-resistant formula simplifies application while being environmentally safe and non-corrosive. Widely trusted in the marine industry, it extends deck life and enhances appearance with minimal shrinkage and easy sanding.

## Description

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- ConstructionAbout TDS SIS440 Caulk:More than 50,000 decks manufactured and installed in 35 years; 166 miles (267 km) of caulked seams per year.
