Polyurethane Dispersions (PUD)

PURIN’s water-based dispersions stand out with their eco-friendly formulations and high-performance features. Their VOC-free structure makes them suitable for many industrial and commercial applications.

Coating Systems

• Durable, flexible, and scratch-resistant coatings for wood, metal, and plastic surfaces
• Suitable for single- or multi-layer applications
• MFFT range: 5–35 °C
• Optional crosslinking systems (e.g., XR 101)

Adhesive Systems

• Suitable for paper, textile, plastic, and leather lamination
• Thermally and chemically resistant with long shelf life
• High bonding strength and heat-activated options

Textile & Functional Applications

• Water-repellent, washable, and breathable coatings
• Modifiable PUD systems for flocking, screen printing, and technical textile processes

Polyurethane Injection Resins

PURIN’s polyurethane injection resins are specially formulated for demanding construction applications such as waterproofing, crack repair, and ground stabilization. Thanks to their reactive structure, these systems cure quickly on-site and offer durable, long-lasting solutions after application.

Key Features

• Available in 1-component (1K) and 2-component (2K) systems
• Water-reactive, expanding formulations
• Low viscosity for effective penetration into microcracks
• Adjustable reaction time (slow or fast curing options)
• Non-corrosive to reinforcement; high alkali resistance
• Can cure into elastic or rigid form depending on requirements

Application Areas

• Stopping water ingress in underground structures (tunnels, basements, retaining walls)
• Crack injection and repair in concrete
• Foundation and wall waterproofing
• Emergency sealing against active water flows in dams, channels, culverts, etc.

Specialty Prepolymer Resins

PURIN offers specialty-formulated polyurethane prepolymer systems for applications requiring high durability, flexibility, and chemical stability. All systems are available in solvent-based or solvent-free versions based on the technical needs of the application.

The prepolymer portfolio includes classic isocyanate-terminated systems as well as advanced structures such as blocked prepolymers and silane-terminated (SPUR) polyurethanes. This diversity ensures both performance and processability across a wide range of applications.

Standard Prepolymer Systems

Formulated with aromatic or aliphatic isocyanates; moisture or reactive curing; customizable in reactivity and viscosity range.

Blocked Prepolymer Systems

Isocyanate groups are temporarily blocked and activated only at specific temperature ranges. These systems enable controlled reactivity and extended shelf life—ideal for temperature-controlled coatings and binders.

Silane-Terminated Prepolymer Systems (SPUR)

Free of free isocyanate; eco-friendly systems that cure upon exposure to ambient humidity to form an elastic structure. Offers excellent adhesion, UV resistance, and aging stability—ideal for sealants and elastic adhesives.

Advantages

• Solvented and solvent-free options available
• Customizable in terms of reactivity, viscosity, cure time, and hardness
• High adhesion strength and elasticity
• Permanent performance on various substrates: concrete, metal, wood, plastic
• Thermal-activation (blocked systems) or high surface tolerance (silane systems)

Application Areas

• Waterproofing, joint fillers, and adhesive systems in construction
• Industrial coatings and elastomer applications
• Long-lasting sealing systems for automotive, marine, and electronics industries

Elastomer Resins

PURIN develops polyurethane elastomer resins designed for applications that demand high strength, flexibility, and resistance to environmental stress. Our portfolio ranges from cold-curing systems to UV-resistant aliphatic elastomers. Systems are formulated with both MDI- and TDI-based isocyanate prepolymers for application-specific solutions.

MDI-Based Elastomers

Chemically stable with low yellowing tendency and broad formulation flexibility. High dimensional stability and low free monomer content make them a safer option for sensitive technical parts.

TDI-Based Elastomers

Provide superior mechanical performance, flexibility, and impact resistance. Maintain shock-absorbing properties even at higher hardness levels. Preferred for applications requiring high abrasion and deformation resistance.

Cold-Cure Elastomers

Cure at room temperature, reducing energy consumption. Ideal for on-site repairs and mobile applications such as electrical insulation, gaskets, etc.

Aliphatic Elastomers

Superior resistance to UV, yellowing, and weather conditions. Offer long-term color stability and aesthetics. Ideal for marine use, automotive exteriors, and facade coatings.

General Properties

• Hardness range: 50 Shore A – 85 Shore D
• High elongation, tear strength, and impact resistance
• Chemical, thermal, and environmental durability
• Colorable and visually stable (especially in aliphatic types)
• Low-VOC, solvent-free options available

Application Areas

• Molded and cast parts
• Gaskets, bumpers, technical components
• Electrical insulation and coatings
• Marine, automotive, and defense industry applications
• Sports equipment and durable consumer products
