COCOON 550 is formulated for protection of exterior surfaces subject to mechanical stresses, impact, and harsh climatic conditions. COCOON 550 is a liquid polyvinyl chloride coating which can be sprayed on any clean, dry building surface. Wherever it is sprayed, COCOON 550 will form a tough, flexible, waterproof skin that will withstand the extremes of temperature, thermal shock, differential substrate movement, and impingement.
OUTSTANDING FEATURES:
Excellent protection to exterior surfaces, including roofing and structural decks, to effectively waterproof and seal against moisture presentation.
Tested by Factory Mutual for combustibility and found to be a fire retardant coating that will inhibit the progress of combustion.
Cocoon has been in practical architectural use for over fifty years.
Approved by the Board of Standards and Appeals of New York City (795-57-SM) for use as a roof covering on hospitals, schools, institutions, commercial and industrial buildings.
Unaffected by intermittent exposure to dilute solutions of alkalies including sodium hydroxide, sodium carbonate, and ammonium hydroxide.
Resistant to exposure to most strengths of mineral acids at ambient temperatures and to all concentrations of salt solutions, alcohols, and greases.
Weathering characteristics permit the use of many different pigments and pigment blends to produce a wide variety of colors possessing excellent stability.
Chemical structure permits infinite touch-up and recoating window (new Cocoon coat softens the old coat and “bites in” to offer provision for future maintenance work).

APPLICATION:
Caution! READ THIS ENTIRE DATA SHEET BEFORE CONTINUING.
All surfaces must be dry, free of dirt, loose debris, oils, grease, or any substance that could interfere with adhesion. All masonry, cement and concrete must be allowed to cure for 30 days or measure 15% maximum on the moisture meter. Ambient temperature in the work area must be at least 55°F. Additionally, all surfaces should be modified in a manner to make them as smooth as possible by removing sharp projections and filling gaps and voids. A minimum surface profile of 1/mm should be maintained for maxi-mum adhesion. After proper masking, prime the entire surface to be coated with Vinyl Bond B, directly from the can by spray or roller, and allow the primer to dry. Close all penetrations through the surface by using a webbing coat. Webbing solution is made by mixing 1 part webbing agent with 3 parts Cocoon 550 to produce a milky, white solution that will support the following coats. Mix ˝ gallon of Cocoon Pigment into a 5 gallon can of Cocoon 550 and mix until the color is uniform. Spray apply the mixed Cocoon 550 in multiple overlapping passes until a 20 mil dry film thickness has been achieved. Properly applied, the coating should be free of voids and pinholes. Voids and pinholes must be re-sprayed to achieve a complete seal. Prior to the removal of any protection or equipment, a thorough inspection of the entire area should be completed and all damage or deficiencies must be repaired and re-sprayed. All termination joints should be sealed with a polyurethane sealant. For recommendations regarding equipment, contact our Technical Department.
LIMITATIONS:
Cocoon 550 must be protected from inclement weather during application. Application should cease upon commencement of precipitation.
MAINTENANCE:
Damaged areas may be repaired by cleaning surface and application of Cocoon 550 as described in the Application section.
PRECAUTIONS:
Read and understand the M.S.D.S. thoroughly. Make sure that all involved parties are familiar with the M.S.D.S. Cocoon 550, in its liquid state, is flammable; proper safety precautions against exposure to open flame, sparks, or other sources of ignition must be taken and strict safety rules enforced.
