Cempatch
SBR

Waterproof polymer bonding aid and mortar additive
 
Description

Cempatch SBR is a pure polymer emulsion, designed to improve the mechanical and waterproofing properties of sand/cement based screeds, mortars and renders. The addition of Cempatch SBR has a strong plasticising effect, thereby allowing a reduction in the water/cement ratio, further improving the flexural, tensile and compressive strength and enabling screeds to be applied down to 10 mm and renders down to 6 mm. 

The addition of Cempatch SBR will also significantly increase resistance to chemical attack, abrasion and freeze-thaw cycling.

Packaging

Cempatch SBR is available in 25 and 200 litre containers.

Consumption/Dosage Rate

Typically 10 - 20% v/w on the OPC weight i.e. 5-10 litre of Cempatch SBR per 50 kg of OPC.

Storage

Protect from frost and store under dry warehouse conditions at a temperature between 10°C and 30°C. 

Shelf Life

Cempatch SBR has a shelf life of 12 months in unopened containers and stored under good conditions.

Application

  • As a bonding agent for bonding new concrete to old.
  • Patch repair compounds.
  • Industrial floors and screeds.
  • Water-resistant renders and screeds.
