Allnex VIACRYL VSC 2990 from Allnex's VIACRYL series high-elasticity modifying base resin range for road coatings is a high-performance solvent-based/solvent-free base resin copolymerized by acrylic and acrylate monomers. Designed specifically for high-quality two-component thick-layer road coatings, its core advantage is precisely adjusting coating elasticity, while having excellent weather resistance and wear resistance
Precise high-elasticity adjustment - Core adjustment function optimizes coating flexibility, adapting to deformation needs of road substrates and reducing cracking risk.
Comprehensive weather and wear resistance - Excellent outdoor aging and UV resistance, outstanding wear resistance, extending service life of road coatings.
Excellent construction performance - Good leveling and strong pigment anti-settling property, ensuring uniformity of thick-layer coating and simplifying construction operations.
Two-component thick-layer road marking coatings: High-quality thick-layer marking coatings such as road lane lines and warning signs, ensuring elasticity and durability.
Expressway protective coatings: Surface protective coatings for expressways, adapting to high-frequency traffic rolling and complex climatic environments.
Urban road heavy-load area coatings: Coatings for heavy-load areas such as urban arterial roads and bus lanes, improving deformation resistance.
