COCOON WEBBING AGENT
Reinforcing Resin Additive. Bridge-Forming Waterproof Support.
COCOON WEBBING AGENT is a specialty resin solution designed as a reinforcing additive for use within the COCOON coating system. When incorporated into compatible COCOON coatings, it is engineered to form a physical bridge over openings, gaps, and irregular substrate conditions—supporting membrane continuity and system integrity.
When properly applied, COCOON WEBBING AGENT produces a fine, dry, cobweb-like filament structure that spans voids and surface discontinuities without collapsing under its own weight. This creates a reinforced transition layer that strengthens the overall waterproofing and air-sealing system.
As part of the COCOON product range, COCOON WEBBING AGENT has been used for decades in architectural and industrial coating applications where reliable bridging, reinforcement, and environmental sealing are required.
Key Benefits
- Bridging Reinforcement
Forms fine filaments that span and close openings and gaps - Structural Support for Membranes
Enhances coating strength across discontinuous or irregular surfaces - Alternative to Fabric Reinforcement
Provides reinforcing capability without traditional embedded fabrics - Water, Air & Dust Barrier Enhancement
Supports sealing against moisture, air, gas, and particulate intrusion - Interior & Exterior Compatibility
Performs in both indoor and outdoor coating systems - Thermal Movement Resistance
Maintains flexibility under thermal cycling and temperature extremes - System Integration
Works as part of the broader COCOON waterproofing and air-sealing system
Typical Applications
- Bridging cracks, joints, and openings in coating systems
- Reinforcement of waterproofing membranes
- Air and gas sealing applications
- Transition areas in architectural and industrial coatings
- Complex substrates requiring additional membrane support

Preparation and Application
Surface Preparation
All surfaces must be dry, free of dirt, loose debris, oil, 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. A minimum surface profile of ½mm should be maintained for maximum adhesion.
Application
After proper masking, prime the entire surface to be coated with COCOON VINYL BOND B, directly from the can, by spray or roller, and allow the primer to dry. When dry, the surface should be glossy and a light blue color.
Webbing solution is made by mixing 1 part of Webbing Agent with 3 parts of Cocoon (by volume) and agitating with an air-driven mixer until it has become a milky white solution (at least 3 minutes). Apply Cocoon webbing coat with the correct spray equipment to an opaque, homogenous covering around pipes, ducts, etc. This membrane will support all of the following coats of Cocoon. The first application of Cocoon over the webbing coat should be a light,
rapid pass to provide the webs some strength and prevent them from breaking when the Cocoon coating is applied.
Recommended Thickness
5 to 20 mils Dry Film Thickness (DFT)
Limitations
Proper ventilation must be provided during application for effective drying of the coating, and all applicators must wear suitable respirators. All webbing work must be protected from inclement weather during application. Application should cease upon commencement of precipitation and be thoroughly inspected prior to re-commencement and force-dried, if necessary, so as to prevent entrapment of water.
Maintenance
If webs are damaged, re-webbing may commence provided that the surface is uncontaminated; otherwise, clean and remove all contaminated material and re-apply.
Precautions
Read and understand the Material Safety Data Sheet thoroughly. Make sure that all involved parties are familiar with the M.S.D.S. Cocoon Webbing Agent, in its liquid state, is flammable, and proper safety precautions against exposure to open flame, sparks, or other sources of ignition must be taken and strict safety rules enforced.
Clean up
Equipment may be cleaned with Acetone
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.
