COCOON VINYL BOND B
Adhesion Promoter & Prime Coat for the COCOON System
COCOON VINYL BOND B is a high-performance adhesion promoter and primer designed specifically for the COCOON series of protective coatings. It is formulated as an adhesive resin solution that conditions and prepares substrates to ensure maximum bond strength and long-term coating performance.
When applied to a clean, dry surface, COCOON VINYL BOND B rapidly develops strong adhesive properties, creating an optimized bonding layer for subsequent COCOON coatings. It is suitable for use on a wide range of interior and exterior substrates, including gypsum board, wood, masonry, concrete, and metal.
Engineered for demanding applications, it maintains adhesive integrity under thermal cycling, mechanical stress, and exposure to aggressive chemical environments. Its flexible bond line resists deformation and cold creep, ensuring stable long-term performance across varying service conditions.

Preparation and Application
Surface Preparation
All surfaces must be dry, free of dirt, loose debris, oils, grease, or any substance that could interfere with adhesion. 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
Application
A minimum surface profile of ½ mm should be maintained for maximum adhesion. After proper masking, prime the entire surface with the Vinyl Bond B directly from the can by spray or roller and allow it to dry. When dry, the surface should be glossy and a light blue color. Prime only what can be comfortably coated in a day so as not to expose the primer to excessive moisture overnight. Do not apply Vinyl Bond B over webbing coat. For recommendations regarding equipment, contact our Technical Department.
Recommended Thickness
1 to 3 mils Dry Film Thickness (DFT)
Drying Time
About 5 minutes
Clean up
Equipment may be cleaned with Acetone
Limitations
Proper ventilation must be provided during application for effective drying of the coating, and all applicators must wear respirators. COCOON VINYL BOND B must be protected from inclement weather during application. Application should cease upon commencement of precipitation.
Maintenance
Damaged areas may be re-primed by cleaning and re-spraying the COCOON VINYL BOND B as described in the Application section.
Storage
Store in a dry area and protect from direct sunlight and freezing. Protect from moisture and foreign materials. Keep container tightly sealed. Shelf life is 2 years from date of manufacture when stored in a factory sealed container between 50ºF (10ºC) and 90ºF (27ºC).
Disposal
Waste disposal must be in accordance with existing federal, state and local environmental control laws. Incineration is the preferred method of disposal.
Read the container label warning and Safety Data Sheet (SDS) for important health and safety information prior to the use of this product.
