Polyurethane Primer Std 927 - China

Product Description

The one-component primer can improve the surface condition of the base layer, making it flatter and smoother, providing a good foundation for the application of waterproof coatings.

At the same time, the primer can also be more compatible with the waterproof coating and enhance the overall performance of the waterproof layer.

One-component primers usually contain special resin ingredients that can penetrate into the tiny pores of the base material to form a mechanical anchoring effect, thereby greatly enhancing the bonding strength between the waterproof coating and the base.

Features

Improve waterproof layer performance Enhance the adhesion of the base Application

Using a one-component primer before applying waterproof coatings can make the waterproof coating more evenly distributed on the surface of the base layer, forming a waterproof layer with consistent thickness and continuity, thus improving the waterproof effect and durability of the waterproof layer.

For example, in roof waterproofing projects, after using a one-component primer to treat the base layer, the waterproof layer’s anti-seepage and anti-aging properties can be significantly improved.

This strong bond ensures that the waterproof layer is not easy to fall off when subjected to external forces (such as slight deformation of the base layer, stress caused by temperature changes, etc.

), maintaining the integrity of the waterproof system.

For example, after applying a single-component primer on a concrete base layer, the resin in the primer will fill the pores on the concrete surface, allowing the waterproof coating to better adhere to the base layer, avoiding problems such as hollowing and peeling in the later stage.
