Moisture-Curing Flexibility Additive
A moisture-curing polyurethane resin based on Toluene Diisocyanate, used as a flexibility additive in conjunction with other products in formulated systems.
Economical flexibiliser for polyurethane formulated systems
Completely solvent-free with >98% non-volatile content
Cures via atmospheric moisture — no additional agents needed
Works as a blending additive in the Kollerdur product range
Spectrapol T15 is a specialist flexibility additive for use in formulated polyurethane systems. Based on toluene diisocyanate as a moisture-curing urethane resin, it acts as an economical flexibiliser in roof coating formulations, adhesives, sealants, putties, and similar compounds.
Compatible with pitch, aluminium, and various formulation types, Spectrapol T15 also serves as a blending additive in the Kollerdur product range. The product is 100% solids and completely solvent-free, with monomeric TDI content below 2%.
With a high flash point of 176°C and NCO content of 2.4-3.0%, Spectrapol T15 provides reliable flexibility enhancement in single-pack sealant formulations and multi-component systems alike.
