Acrylic Binder for Exterior Masonry Coatings: PLIOTEC DPR 30

The durability and maintaining the aesthetic quality of exterior surfaces is essential for high-performance professional paint systems. Coatings must stand up to dirt, UV light, rain, and fluctuating temperatures, while remaining easy to apply and compliant with environmental regulations.

In this context, Synthomer introduces PLIOTEC® DPR 30, an advanced acrylic binder for exterior masonry coatings that delivers breakthrough performance in real-world applications.

A New Standard in Exterior Performance

Designed specifically for high-performance exterior masonry paints, PLIOTEC DPR 30 combines advanced polymer morphology, excellent coalescence, and high solids content to meet the needs of both professional painters and manufacturers.

This new acrylic copolymer features:

• Low VOC content (<0.2 g/L)
• Excellent resistance to dirt pick-up
• Strong resistance to alkalis and efflorescence
• UV durability and colour retention
• High formulation flexibility for D2 (thin film) and D3 (thick film) systems
• Washability and long-term film integrity

These characteristics make it ideal for vertical exterior walls, façades, cementitious renders, and textured masonry applications.

Key Properties of PLIOTEC DPR 30

From a formulation standpoint, PLIOTEC DPR 30 offers a combination of physical and application advantages:

• Minimum Film Forming Temperature (MFFT): 5 °C
• Glass Transition Temperature (Tg): 10 °C
• Solid Content: 50%
• Viscosity (60 rpm, 25 °C): 150 mPa·s
• pH: 8.5
• VOC: < 0.2 g/L

Its controlled dispersion morphology allows formulators to optimise film quality while maintaining balance between mechanical strength and surface properties.

Formulation Flexibility: D2 and D3 Paint Systems

Thin Film (D2) Masonry Paint

• Solid content: 66.7%
• PVC: 57.3%
• Specific gravity: 1.56
• VOC: 2.5 g/L
• Viscosity: 6680 cP
• MFFT: 4 °C

Thick Film (D3) Masonry Paint

• Solid content: 69.5%
• PVC: 48.5%
• Specific gravity: 1.52
• VOC: 2.6 g/L
• Viscosity: 5460 cP
• MFFT: 4 °C

Both systems exhibit excellent workability, smooth application and robust film formation.

Dirt Pick-up Resistance: Best-in-Class

A major differentiator of PLIOTEC DPR 30 is its outstanding dirt pick-up resistance (DPUR):

• In D2 formulations, PLIOTEC DPR 30 showed ΔE* = 19.5, compared to 38–43 for other binders.
• In D3 systems, it reached ΔE* = 21.8, while references exceeded ΔE* = 50.

These results confirm that paints formulated with PLIOTEC DPR 30 are easier to clean and stay brighter over time.

Water Absorption and Permeability Performance

In benchmarking studies, PLIOTEC DPR 30-based paints achieved:

• Water absorption class W3 (low absorption)
• Vapour permeability class V2 (medium permeability)
• Excellent density (1.52–1.56) and solid content up to 70%

This positions PLIOTEC DPR 30 as a premium solution for damp-proofing and surface protection in challenging environments.

Colour Retention and UV Stability

Exposure to QUV-B radiation and accelerated weathering demonstrated that coatings using PLIOTEC DPR 30 maintain colour and integrity significantly better than pure acrylic reference binders.

Thanks to the polymer backbone and improved film integrity, yellowing and chalking are drastically reduced, even after extended outdoor exposure.

Eco-Compliant and Sustainable

As regulations evolve, paint formulators need to rely on binders that meet low-emission standards without compromising on performance.

PLIOTEC DPR 30 is:

• APEO-free
• Very low VOC (<0.2 g/L as supplied)
• Suitable for indoor and outdoor use in environmentally sensitive applications

This makes it ideal for eco-label products or green building certifications.

The Perfect Binder for Demanding Professionals

Whether used in premium façade paints, textured coatings, or anti-efflorescence finishes, PLIOTEC DPR 30 empowers formulators to deliver best-in-class performance and sustainability.

Its compatibility with a wide range of pigments, fillers, and rheology modifiers also makes it a versatile choice for product development.
