ADHESIVES & SEALANTS
Specialty additives, adhesion promoters and functional fillers engineered for bond strength, wetting, air release, density control, reinforcement and long-term reliability.
The bond is only as good as the interface.
Adhesive performance begins before cure: substrate energy, wetting, trapped air, filler packing and interfacial chemistry decide whether a formulation builds durable contact.
Geocon supports formulators across waterborne, solventborne and reactive systems with additive families that improve processability, control density and reinforce the cured network—without losing sight of compatibility and application method.
One interface challenge.
Six operating environments.
Construction
Joint sealants, glazing, façade, flooring, panel bonding, tile systems and weatherproofing.
Automotive & Transport
Structural bonding, hem-flange, body sealing, interiors, composites and lightweight assemblies.
Packaging & Labels
Carton sealing, paper converting, laminating, labelling and pressure-sensitive applications.
Electronics & Electrical
Potting, encapsulation, gasketing, component bonding and thermally functional assemblies.
Industrial & Appliances
Metal, glass, plastic, wood and composite bonding with controlled cure and gap filling.
Marine & Composites
Deck and hull sealing, FRP assembly, vibration-resistant joints and moisture-exposed interfaces.
Match the additive
to the binder.
Acrylic / PVA / Latex
Wetting, defoaming, microbial protection, rheology and filler dispersion are key.

| Formulation challenge | Geocon product route | Primary contribution |
|---|---|---|
| Poor substrate wetting | Wetting agents · fluorosurfactants · silanes | Improved contact and spread on compatible low-energy or contaminated surfaces. |
| Weak interfacial adhesion | Silane adhesion promoters · filler treatment | Coupling between organic resin and inorganic or polar substrate. |
| Foam and entrained air | FOAMSTAB silicone / silicone-free / mineral-oil defoamers | Air release, lower porosity and improved coating or bead appearance. |
| High density | 3M Hollow Glass Microspheres | Weight reduction, higher volume yield and gap filling at controlled strength. |
| Shrinkage / dimensional control | GEOSPHERES · mineral fillers · milled glass fibres | Build, reduced resin demand and reinforcement in compatible systems. |
| Sag and bead profile | Functional fillers · rheology support | Controlled body, shape retention and vertical-surface application. |
| Hygienic joint requirement | Antimicrobial additives | Selected antimicrobial functionality subject to formulation validation. |
| Water / soil repellency | Fluorosilanes · surface modifiers | Lower surface energy and easier cleaning where compatible. |
| Composite repair strength | Milled glass fibres · adhesion promoters | Reinforcement and load transfer in selected thermoset compounds. |
| Thermal management | Boron nitride · functional fillers | Electrically insulating thermal-filler pathway for electronic bonding systems. |
Design for application and service-not only initial bond strength.
A useful additive must survive mixing, application, cure and ageing. Screen it against the complete performance envelope.
Start with the substrate pair and failure mode.
Recommended starting levels and addition methods must be established for the selected grade and verified in the complete formulation.
Bring us the formulation,
substrate and failure mode.
Our team can help shortlist additive chemistry, define a dosage ladder and structure comparative tests before production evaluation.
