Each catalyst is designed to fulfill a specific application requirement, depending on the formula composition and curing conditions. While the acid catalysts provide the fastest cure and lower curing temperature, blocked catalysts are typically chosen for systems requiring greater package stability p-TSA in Isopropanol Code # DYNACAT® - I40 Assay % 40 Appearance Clear Liquid Specific Gravity 0.999 @ 25°C p-TSA in Water Code # DYNACAT® - W40 Assay % 40 Appearance Clear Liquid Specific Gravity 1.12 @ 25°C DDBSA in Isopropanol Code # DYNACAT® - DB70 Assay % 70 Appearance Dark Liquid Specific Gravity 0.970 @ 25°C Amine Blocked Acid Catalysts p-TSA in Isopropanol Code # DYNACAT® - 5500 Assay % 25 Appearance Clear Liquid Specific Gravity 0.970 @ 25°C p-TSA in Isopropanol & Methanol Code # DYNACAT® - 5501 Assay % 25 Appearance Clear Liquid Specific Gravity 0.960 @ 25°C DDBSA in Isopropanol Code # DYNACAT® - 5525 Assay % 25 Appearance Light Straw Liquid Specific Gravity 0.900 @ 25°C Get In Touch Name Email Address Company How did you hear about us?
