ADDITYS offers a broad range of curing agents and peroxide accelerators for a wide range of applications:
DETDA (CAS: 68479-98-1) is a liquid aromatic diamine chain extender with high reactivity, designed for the hardening of polyurethane systems at ambient temperature. DETDA is also commonly used in polyurea spray coatings and epoxy resins, in order to enhance their mechanical properties, and chemical resistance.
DMTDA (CAS: 403-240-8) is a liquid aromatic diamine with low reactivity, designed for the controlled hardening of polyurethane cast elastomers. DMTDA allows to produce cast parts with superior mechanical properties, and with reduced health and environmental risks, compared to other polyurethane hardeners.
CLEARLINK 1000 (CAS: 154279-60-4) is a secondary cycloaliphatic diamine primarily designed for use as chain extender by reaction with aliphatic isocyanates to produce light-stable elastomeric coatings. It is a safe, low viscosity liquid with a reactivity substantially lower than that of other commercially available aliphatic diamines.
CLEARLINK 1080 is a secondary cycloaliphatic diamine that has been designed for use as chain extender to formulate light-stable elastomers and coatings. CLEARLINK 1080 is characterised by a very low viscosity and a slow reactivity. It is compatible with a wide range of polyols, co-curatives and other polyurethane chemicals.
UNILINK 4100 (CAS: 101-96-2) is a liquid aromatic diamine developed as slow-reacting chain-extender for TDI and MDI-based polyurethane elastomers. As a di-functional diamine, UNILINK 4100 builds linear polymer networks, allowing the polyurethane formulator to control the degree of cross-linking by the use of higher functional isocyanates and polyols.
UNILINK 4200 (CAS: 5285-60-9) is a low viscosity aromatic diamine used as chain extender in polyurethane elastomers and polyurea spray coatings. Thanks to its relatively low reactivity, UNILINK 4200 can be used both in TDI or MDI formulations. UNILINK 4200 is also used in flexible polyurethane foams to improve tear strength and dimensional stability while reducing foam density.
ASPARTYS 220 is an amino-functional aspartic resin designed for fast reaction with aliphatic isocyanates, particularly suited to spray coating applications. ASPARTYS 220 is characterised by a low viscosity and an excellent UV-light durability.
ASPARTYS 420 (CAS: 136210-30-5) is an amino-functional aspartic resin showing a high reactivity towards aliphatic isocyanates. ASPARTYS 420 is characterised by a medium viscosity and an excellent UV-light durability, making it particularly suitable to the formulation of high quality top coats exposed to direct UV-light.
ASPARTYS 520 (CAS: 136210-32-7) is an amino-functional aspartic resin showing a medium reactivity towards aliphatic isocyanates, designed for the formulation of very high quality top coats of high solid content. ASPARTYS 520 is characterised by a medium viscosity and an excellent UV-light durability.
FIRSTCURE MHPT (methyl,hydroxyethyl-p-toluidine, CAS: 2842-44-6) is an amine-based cure accelerator used to enhance polymerisations through the activation of organic peroxide initiators. These polymerisations include unsaturated polyester resins, vinyl-ester resins, and acrylate systems. FIRSTCURE MHPT is typically used in concentrations ranging from 0.1% to 0.5%.
PTE (p-toluidine ethoxylate, CAS: 103671-44-9 and 3077-12-1) is a light yellow viscous liquid used as cure accelerator in peroxide initiated systems, such as unsaturated polyester, vinyl ester and acrylic systems. Typical applications: acrylic floorings, road marking paints, car body repair putties, chemical fixings and prosthetics. PTE is a good alternative to DMPT.
DPPT (dipropoxy-p-toluidine, CAS: 38668-48-3) is a light yellow solid used as polymerisation activator in peroxide initiated systems, particularly systems based on acrylate and methacrylate monomers. It is characterised by a very good compatibility with these resins, and a high reactivity.
