Applications

UP – 503 is intended for mastic resin in non-continuous systems. This resin has a high dilute ability by solvent and excellent powder absorption. The mastic produced from this resin has excellent and stable thixotropic properties. In order to cure the produced mastic, it is necessary to add about 0.1% amine (such as dimethyl aniline) and 1-2 % benzoyl peroxide paste.
