Overview
N,N,4-Trimethylpiperazine-1-ethylamine (CAS 104-19-8 ), also known commercially as Addocat PP, is a tertiary amine used as a catalyst in polyurethane and polymer systems.
It accelerates curing and crosslinking reactions, allowing formulators to control reaction speed and network development in finished products. This chemical is essential for high-performance manufacturing.
In polyurethane foam and elastomer production, it functions as a blowing and gelation catalyst, balancing the competing reactions that determine cell structure and mechanical performance.
Coatings formulators use it to tune cure speed in two-component polyurethane systems, particularly where pot life and through-cure need to be matched to specific application conditions.
In adhesive and sealant manufacturing, it supports crosslink density development, directly affecting bond strength and flexibility in the cured product. It is a versatile additive for many industries.
It is also used in rigid and flexible polymer systems where controlled amine catalysis is required during processing. This ensures consistent quality and performance across various polymer grades.
N,N,4-Trimethylpiperazine-1-ethylamine is supplied as a liquid. Technical grade is the standard commercial form for industrial catalyst applications and large-scale chemical processing.
It is typically available in drum and IBC quantities suited to industrial-scale polyurethane and polymer processing operations. This ensures reliable supply chains for global manufacturing needs.
