Changing rheology and strength of adhesives 

The three-dimensional network from the microfibrillated cellulose of Exilva provides benefits on rheology as well as physically providing strength effects. It is also compatible with a high number of waterborne adhesive systems like:

• Polychloroprene
• Melamine Urea Formaldehyde & Urea Formaldehyde (UF)
• Starch adhesives (including adhesives for corrugated packaging)
• PolyUrethane Dispersions (PUD)
• PolyVinylAlcohol (PVA)

One of the strongholds of Exilva is its ability to function in a wide variety of pH, salt conditions, and temperature.

The benefits of Exilva on rheology and consequently the adhesive performance is many:

• During storage: High viscosity at rest, Robust stability to pH, shear and temperature
• During application: Enhanced sprayability, Anti-sag/anti-drip, Eased unloading of IBC's (no residues), Improved resin/hardener mix
• Durability: Improved tensile strength, Improved end-product quality, Improved appearance, Improved tail seal bond strength
• Sustainability: Lowering CO2 footprint, EHS friendly (no dusting during production)

Starch Adhesives for Corrugated Packaging

One innovation example is a new sustainable starch-based glue in corrugated boards that in the future can offer corrugators to replace boron derivatives in their glue recipes. Already available is the option to add Exilva as an additive for speed and productivity enhancement to current glue solutions. This may then be followed with a step-wise reduction of the toxic boron compound to be in front of market, regulatory and corporate social responsibility demands. 

Advantages from Exilva in adhesive systems:

• Improves rheology – strong thickening and shear thinning
• Very high water holding capacity – improves control of dry-out time
• Fast viscosity recovery, with thixotropic characteristics
• Improves dispersion and anti-settling of particles
• Long storage stability
• Increases flexibility in material handling and processing – stable in extreme environments and no rehydration time required
• White, VOC free and odourless
• 100% natural and infinitely sustainable – improves your environmental profile
