PUB 401

Description

PUB 401 is a polyurethane-bitumen based, two component, self-levelling, cold applicable dilatation and joint sealant material.

Fields of Application

It is applied on horizontal dynamic dilatations and joints for water impermeability and filling.

Features and Benefits

It is elastic. It keeps its elasticity between -20°C and +120°C.
It is cold applicable product. Provides easy and fast application.
It is durable against abrasion and aged.
It has excellent mechanical and chemical resistance.
It is self levelling.
Excellent adhesion on the applied surfaces.

Application Procedure

Preparation of Substrate

The surface must be dry and clean before application. All joints before filling shall be carefully cleaned by metal brushing or sanding. The dust should be removed by pressured air. PUB 401 causes foaming when applied on moist surfaces.

Application Method

Component A and B is mixed under low speed mixer until homogenous mixture obtained. Mixture must be used within 30 minutes. Otherwise gelling occurs and it cannot be recovered. PUB 401 must be used only on horizontal joints. The application surface should be protected from water minimum 6 - 8 hours.
