Ultrabond Blue 52 PAS
Ultrabond Blue 52 PAS is an unsaturated polyester, adhesive paste with a tenacious bond. It is non-sagging and can be used for filleting. The cured material has good adhesion to a variety of substrates including GRP, steel, aluminium, wood and brick. The bonding paste contains a blue catalyst colour change indicator. Once catalyst is added the blue colour of the indictor disappears to reveal the natural off-white colour of the bonding paste.
