Perma Master Prime-CN

NON SOLVENTED EPOXY BONDING AGENT AND PRIMER FOR CONCRETE SURFACES.
DESCRIPTION

Porosity of concrete surfaces, moisture and the alkalinity of the concrete surface makes it difficult for the epoxy products to bond with the concrete bases effectively. To get over these problems an effective epoxy bonding agent or a primer is made use of. Perma Master Prime-CN is a two component product based on non solvented epoxy base and epoxy hardener. Perma Master Prime-CN binds the epoxy products firmly to the cementitious bases.

Perma Master Prime-CN

PRIMARY USE

To bind epoxy mortars and flooring products to the concrete base taking care of the porosity of the base and mobilizing the particles of the mortars into the crevices and holes in the base.

APPLICATIONS

Perma Master Prime-CN is applied on a dry concrete surface which is at least 28 days old before laying epoxy flooring materials or coating. Perma Master Prime-CN forms a part of the system with Perma Master Floor-SL, Perma Master Floor-HD and Perma Heavy Duty Mortar(HDM).

ADVANTAGES

1)Perma Master Prime-CN thoroughly wets the concrete surface and mobilizes the particles of the epoxy products effectively on the concrete surfaces and makes it easier for epoxy products to bond with the concrete effectively.

2)Perma Master Prime-CN being moisture tolerant makes the priming easy. There is no need to blow torch the surfaces to make them bone dry. A reasonable dry surface is good enough.

3)Perma Master Prime-CN is resistant to alkalis hence there is no need for the cumbersome process of acid etching the surface
