Bostik Offers New Material

On Marine Grade Sealants

Bostik Division, Emhard Chemi- cal Group, Middleton, Mass., is of- fering new free literature on its ma- rine grade sealants—Bostik 320

Polysulfide/Sealant, Bostik 620 Sili- cone Sealant/Adhesive, and Bostik 920 Urethane Sealant/Adhesive.

The explanatory text of the litera- ture, which also contains color pho- tos of the sealants along with draw- ings illustrating their use, describes

Bostik 320 as a one component ma- rine grade polysulfide sealant that chemically cures to form tough, low modulus, elastomeric seals. It is said to stay flexible even in joints sub- jected to considerable movement and to be particularly effective for applications below the waterline where disassembly may later be nec- essary. It should be considered for portholes, keel plates, keel seams, depth finders, instruments, and en- capsulated nuts and bolts.

March 1, 1985

Bostik 620 is listed as a one part silicone sealant that cures to form extremely flexible seals to a wide variety of boatbuilding materials. It is specifically recommended for joints above the water line that may later need to be disassembled, and it should be considered for grip rails, lights, horns, portholes and mount- ings for antennas.

Bostik 920 is described as a one compound marine grade urethane sealant that is said to provide excep- tional adhesion to most boatbuild- ing materials. It is recommended for any marine application, above or below the waterline, where a perma- nent seal is desired and should be considered for deck to hull assem- bly, hull seams, keel joints and un- dermoldings.

In addition to product descrip- tion, the literature gives the physi- cal properties, product characteris- tics, and features and uses, as well as terms and conditions of sale.

A comparative data chart in the brochure lists such information as product data, container sizes, colors, application method, extrudability, track free time, and shore hardness; a performance data chart lists the type of material each sealant is rec- ommended for, as well as environ- mental resistance in water, salt water, oil, gasoline, and outdoor weathering.
