Europe’s coatings and flooring sectors are experiencing a rapid transition toward sustainable materials, low-VOC technologies, and REACH-compliant raw materials. As Germany and France tighten environmental standards, manufacturers are looking for renewable polyurethane inputs that offer high performance while reducing regulatory risks.
Drothane™ Bio-Polyols developed by D.R. Coats Inks & Resins Pvt. Ltd. are engineered specifically for this shift. With castor-based chemistry, low VOC profiles, and strong performance in coatings, flooring, and adhesives, they provide European formulators with a reliable pathway to sustainable polyurethane systems.
DRC currently exports to more than 55 countries, supporting customers with REACH-aligned, renewable polyurethane raw materials for next-generation coatings, adhesives, and flooring applications.
1. Why Drothane™ Bio-Polyols Fit Western Europe’s Requirements
Renewable Castor-Based Backbone
Derived from castor oil, a rapidly renewable and non-food competing biomass, Drothane™ aligns strongly with European Union sustainability goals and carbon-reduction ...
... strategies. This makes it ideal for manufacturers working toward greener, more circular material choices.
REACH Compliance for Simplified Qualification
All inputs used in Drothane™ bio-polyols are carefully selected to comply with REACH, helping European formulators reduce regulatory burdens and ensure continuous supply-chain stability.
Low VOC for Better Indoor Air Quality
Strict VOC and indoor air-quality regulations in Germany and France (AgBB, AFNOR, EU Ecolabel) make low-emission materials essential. Castor-based polyols inherently support healthier, safer, and more eco-friendly formulations.
High Mechanical & Chemical Performance
Drothane™ grades offer a balance of strength, adhesion, flexibility, and chemical resistance meeting the demands of both industrial and architectural polyurethane applications.
Consistent, Scalable Quality
Manufactured under ISO 9001 and ISO 14001 systems, Drothane™ bio-polyols deliver tight QC control and batch-to-batch consistency required by European PU manufacturing plants.
2. Drothane™ 1145 & 1150 - Core Castor-Based Polyols
These two grades form the backbone of DRC’s sustainable polyurethane offerings for coatings, adhesives, and flooring applications.
Drothane™ 1145 - High Hardness & Strong Adhesion
Ideal for:
• Industrial PU coatings
• PU flooring binders
• High-hardness protective topcoats
• Adhesives and primers
Key Features:
• High OH value for strong crosslinking
• Excellent adhesion to concrete and metal
• High hardness with strong impact resistance
• Good chemical and solvent resistance
• Low VOC and Bisphenol-A free
Drothane™ 1145 delivers durability, hardness, and chemical resistance making it suitable for industrial flooring and heavy-duty coatings used widely across Germany and France.
Drothane™ 1150 - Flexible & Chemical-Resistant Polyol
Ideal for:
• Flexible coatings and sealants
• Elastomeric flooring
• Construction adhesives
• Waterproofing membranes
Key Features:
• Excellent flexibility and elongation
• Smooth film formation
• Good compatibility with MDI & PMDI
• Strong chemical resistance
• High adhesion for PU sealants and adhesives
Drothane™ 1150 is preferred when elasticity, crack-bridging, and resilience are required—especially in construction sealants and elastomeric coatings.
3. Drothane™ 2761 / 2762 / 2763 - Water-Based Polyol Emulsions
Western Europe is moving strongly toward waterborne and low-VOC flooring technologies. Drothane™ 2761-2763 address this transition with advanced water-dispersible properties.
Zero-VOC, Self-Levelling, One-Coat Systems
Traditional flooring often requires multiple coats (primer + base + topcoat). Drothane™ emulsions allow single-coat systems, reducing labor, curing time, and material consumption.
Industrial-Grade Performance
These emulsions offer:
• Strong resistance to oils, alkalis, and acids
• Excellent thermal shock resistance
• Smooth, self-levelling film formation
• Excellent adhesion on concrete
Ideal for Hygiene-Critical Environments
• Food processing
• Pharma manufacturing
• Commercial kitchens
• Industrial warehouses
3K Cementitious PU System Compatibility
Typical Mixing Ratio:
Polyol: Isocyanate: Cement = 100: 115: 500
This yields high compressive strength, chemical resistance, and mechanical durability an essential combination for European industrial flooring.
4. Broader Bio-Polyol Customisation Capabilities
Beyond the primary grades highlighted above, DRC also manufactures a wider portfolio of specialty bio-polyols that vary in:
• OH value
• Viscosity
• Flexibility or hardness
• Molecular weight
• Renewable content
• Reactivity
This allows European customers to request custom-designed polyols tailored for coatings, adhesives, flooring, 3K PU systems, waterproofing membranes, or hybrid chemistries.
5. Sustainability Advantages for European Manufacturers
Lower Carbon Footprint
Castor-oil-based polyols significantly reduce environmental impact compared to petrochemical alternatives.
Non-Food, Non-Land-Intensive Feedstock
Castor does not compete with food crops or require irrigated farmland supporting responsible sourcing.
Aligned with EU Low-Emission Building Programs
Low-VOC systems are increasingly required for public procurement, flooring contracts, and environmentally certified buildings.
6. Key Applications in Western Europe
Drothane™ Bio-Polyols support multiple polyurethane systems, including:
• Industrial and decorative floor coatings
• PU screeds and PU cementitious flooring
• Construction adhesives and sealants
• Waterproofing membranes
• Protective coatings for metal and concrete
• 2K & 3K PU coating systems
These applications mirror the demands of Western European industries focusing on durability, sustainability, and compliance.
Drothane™ Bio-Polyols deliver a high-value combination of sustainability, REACH compliance, performance, and consistency precisely what Western European manufacturers need today. With castor-based chemistries, low-VOC performance, and both solvent-based and water-based options, the Drothane™ range provides a strong, future-ready solution for coatings, flooring, adhesive, and sealant systems.
DRC’s commitment to innovation, global supply capability, and high-quality manufacturing ensures European formulators a long-term, dependable partnership for specialized polyurethane requirements.
