Questions and answers

Co to jest podkład Reaktywny ?

To 2-komponentowy reaktywny podkład(grunt) poliwinylowy(wash primer), o wysokich właściwościach antykorozyjnych, nakładamy go na powierzchnie metalowe. Rolę aktywatora(utwardzacza) pełni odpowiednio stężony kwas fosforowy. W wyniku kontaktu z metalem otrzymujemy warstwę fosforanów żelaza, która tworzy barierę dla czynników klimatycznych.
