Polyaziridine
Polyfunctional aziridine adalah molekul multifungsi yang digunakan untuk meningkatkan sifat fisik dan kimia pada sistem coating, tinta, dan adhesive, baik berbasis air maupun non-air.
Crosslinking densitas tinggi
Curing pada suhu ruang
Bebas formaldehyde dan isocyanate
Bebas MDA
Efektif pada penggunaan dosis rendah
Pengaruh Konsentrasi Polyaziridine terhadap Tack, Adhesi, dan Kohesi
Meningkatkan ketahanan terhadap air dan bahan kimia.
Meningkatkan ketahanan mekanik terhadap gesekan, goresan, abrasi, keausan, black heel mark, dan fingernail mark.
Meningkatkan kekuatan kohesif lapisan.
Efektif sebagai tack modifier untuk mengatur tingkat kelengketan.
Aplikasi dapat dilakukan pada suhu ruang maupun melalui proses heat curing, baik untuk sistem berbasis air (aqueous) maupun berbasis pelarut (solventborne). Produk ini fleksibel dan dapat menyesuaikan dengan berbagai kondisi dispersi yang tersedia, serta mempertimbangkan pot life, kemudahan penanganan (handling), dan metode penambahan (addition) dalam formulasi.
Crosslinker ini ditambahkan ke produk formulasi tepat sebelum digunakan. Sistem ini merupakan sistem dua komponen (2K system), bukan sistem satu komponen (1K system).
Tingkat penggunaan umumnya berkisar antara 1% hingga 3% terhadap formulasi akhir. Jumlah optimal untuk mencapai hasil yang diinginkan sebaiknya ditentukan melalui pengujian (eksperimen).
Produk harus ditambahkan secara perlahan dengan pengadukan yang baik (good agitation), baik dalam bentuk murni maupun yang telah dipre-mix ke dalam larutan. Jika dilarutkan, disarankan menggunakan pelarut tanpa hidrogen aktif. Air dapat digunakan, asalkan produk yang telah diencerkan segera diaplikasikan ke dalam sistem.
Setelah penambahan, sistem umumnya memiliki pot life sekitar 12–24 jam hingga 4–8 jam, tergantung jenis sistem, suhu, dan pH. Pengujian pot life untuk setiap formulasi sangat disarankan guna memperoleh sifat akhir yang optimal.

PZ-33
CAS Nº:57116-45-7
Molecular Formula : C20H33N3O7
Appearance : Slight yellow liquid with amine-like odor
Aziridine Functionality : 3.3
Density (at 25ºC) : 1.15-1.17 g/ml
Viscosity (at 25ºC) : < 4000 cp
Ethylene imine polyurea based bi-functional agent that may be formulated as 25% active matter waterborne dispersions and used as a crosslinker for aqueous coatings, inks, and adhesives to promote both physical and chemical properties.
The aziridine end groups can react with active hydrogen as found on carboxyl groups of acrylic emulsions or polyurethane dispersions.
As a waterborne product, the product is easy to mix with aqueous bases targeted to heat curing 2K processes. 80ºC are usually enough to start the crosslinking reaction.
