SIS 440 Caulking provides the durability boat owners require. 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. The material does not sag during cure. Once cured, it has excellent temperature stability and chemical resistance. This neutral cure is non-corrosive to all substrates.
- One-part polymer adhesive/sealant neutral cure
- No primer necessary (when application instructions on packaging are followed as written)
- Over 35 years of proven success
