Perma-Patch, LLC is thrilled to announce that its groundbreaking product, 6690 ColdFuze, has become the first cold pour crack sealant to meet the rigorous ASTM D6690 standard for crack sealants and ASTM C920 standard for joint sealants. This milestone underscores Perma-Patch’s dedication to innovation and excellence in asphalt and joint sealing solutions.

Understanding ASTM D6690 and C920 Standards

The ASTM D6690 standard sets the benchmark for performance in crack sealants used on asphalt pavements, while ASTM C920 is the standard for elastomeric joint sealants used in building construction. Meeting these standards ensures that products can withstand harsh environmental conditions and deliver lasting repairs. For years, the industry has relied on hot pour solutions to meet these standards, but Perma-Patch has now successfully introduced a cold pour alternative that covers both crack and joint sealing.
