    Sulphonic acid amine catalyst T-3218

    1.Description

    Description: T-3218 is Sulphonic acid amine catalyst which could be used as catalyst for Powdelink 1174 system. T-3218 suitable for exterior small textured wrinkle finish at dosage of 0.5-1.5%. 


    2.Typical physical data

    Appearance White fine powder
    Solid content(%) ＞99%

    Curing condition：200℃×15min BBM 0.2-0.4% post-added can get bigger texture.　 MCC 0.2-0.4% post-added in can get bigger wrinkle finish


    4.Characteristics

    ①Normally PU resin content 55-65%, more bigger  and good performance wrinkle finish depends on higher resin content.

    ②Polyurethane (hydroxyl value 35±5) combine with curing agent T-1174 chemical ratio is 94/6;curing gent T-1530 IS 83/17;1% T-1530 replace of T-1174 could be used to enlarge the texture and increase the gloss of the film 

    ③2-4% epoxy resin can be used to enlarge the texture and reduce the gloss of film.
