Fast and stable bonding pastes for filling cracks and surface defects, even on high thicknesses


Poly3 filler bonding pastes are formulated to meet the needs of repair and finishing, ideal for filling cracks, holes, channels, empty spaces and small surface defects. They offer:

  • Rapid hardening even on medium and high thicknesses
  • Vertical stability with limited shrinkage
  • Excellent adhesion and sandability for finishing phases

These bonding pastes are widely used in repair and finishing processes, where it is necessary to apply them in one or more passes to reach even significant thicknesses without losing stability or causing defects. The range includes specific versions for:
  • corner rounding, with formulations that prevent shrinkage and the formation of bubbles or voids even in difficult-to-treat areas;
  • direct contact with gelcoat, thanks to isophthalic, iso-npg or vinyl ester resins that guarantee excellent compatibility and durability;
  • surface smoothing, particularly suitable for the finishing and start-up phases, with quick drying, easy sanding and excellent adhesion to subsequent fillers.

Poly3 filler bonding pastes are the ideal choice for those looking for reliable and high-performance products that facilitate repair work, ensuring long-lasting, superior-quality results. With Poly3, you have a partner that supports your production process with cutting-edge technical advanced solutions.
