Dispersion, wetting, adsorption and rheology determine storage and application state.
BIOTEN | BIO-BASED COATINGS
Bring bio-based carriers into interfaces, film formation and long-life surfaces.
For architectural, wood and functional coatings, BIOTEN places bio-based waterborne materials within the full interaction among emulsion, pigments and fillers, substrate and application window—engineering compatibility, film formation, adhesion, hiding, surface feel and durability as one formulation system.

Bio-based Coatings
Coating performance emerges from coordinated multiphase interfaces.
Polymer, pigments and fillers, additives, substrate and environment jointly determine film formation. Bio-based content is one material attribute; product value must also hold through application and long-term surface use.
Concrete, putty, wood and composite substrates require different penetration and adhesion routes.
Minimum film-forming temperature, drying, humidity and applied thickness affect film continuity.
Hiding, surface feel, stain resistance, water resistance and maintenance interval shape the final experience.
A material logic that can be observed, decomposed and reviewed.
Place the material role, complete formulation, process conditions and application stage in one system—explain the phenomenon first, then design the experiment.

Real substrateWalls, wood and composite surfaces
Treat the coating as an interfacial system.
Observe wetting, penetration, film formation and surface function from the substrate upward to locate the causes of cracking, mottling, weak adhesion, reduced stain resistance or a narrow application window.

Turn different application objects into distinct development tasks.
Each scenario has a different material role, formulation boundary and evaluation method. One generalized conclusion cannot cover every application.
Architectural coatings
Build a complete system around dispersion, application, hiding, film formation and wall maintenance.
- Pigment and filler compatibility
- Application window
- Wall durability
Wood coatings
Connect wood penetration, grain appearance, intercoat adhesion and surface feel.
- Wood wetting
- Intercoat adhesion
- Natural feel
Functional coatings
Organize carriers and functional components around stain resistance, protection, skin-contact feel or lower-carbon targets.
- Functional Carrier
- Interface Regulation
- Surface design
Urban-renewal surfaces
Design a deliverable coating system around the existing substrate, application environment and maintenance interval.
- Substrate diagnosis
- System compatibility
- Long-term maintenance
A continuous development pathway from problem brief to application conclusion.
Each step defines its input, test object and next decision so material R&D remains connected to real application conditions.

SCOPE & EVIDENCE
Coating results are jointly determined by formulation, substrate, application and use environment.
Properties of an emulsion or carrier cannot directly represent the adhesion, water resistance, stain resistance, weathering or environmental performance of a finished coating. The project must bind the pigment and filler system, substrate preparation, film thickness, application and cure, use conditions and test method.
- Validate the material–formulation interface first, then move to representative substrates and complete-coating evaluation.
- Certification, regulatory and environmental statements are governed by the specific product, valid documents and target market.
