Technology Based Product QST Cretebond Plus

 

  Description
 

CreteBond is a specially designed polymer that modifies cement to provide excellent performance and adhesion. Unequalled bonding strength to most surfaces.

  Uses
 

The core usage of CreteBond is to serve as a primer coat onto polystyrene board, plywood and plasterboard before conventional render takes place and protection against corrosion for steel surfaces. Different grades of are available depending on the type of surface that is required to prime and the flexibility that is to be achieved.

  Advantages Of Using CreteBond
  • Improved adhesion to the background
  • Improved tensile and flexural strength
  • Improved resistance to water and water vapour penetration
  • Reduced water : cement ratio
  • Improved Chemical resistanc
  • Improved frost resistance
  • Prevents surface dusting
   
  Coverage
  The CreteBond modified cement coating can give bond strengths above 3.5N/sq.m (500psi). In practice, the background or the render usually breaks first.

Under the electron microscope the cementitious nucleus shows their strength through the growth of interlocking fibrils of tobermorite gels. This gel is the hydration product of the reaction of various calcium, aluminium, magnesium and silicon compounds in cement and water.

It is an internal reaction within individual cement particles, with the nodules or fingers of tobermorite gel growing out from the particle like stalactites or stalagmites. The more the fibrils from adjoining cement particles intermesh or greater strength of the total mix.



CreteBond The spheres of polymer will coalesce ( merge together ) to form a continuous polymer matrix, which coats and encapsulates the cement particles, fibrils, additives, selected filters and aggregate grains.



The polymer matrix acts as a barrier to maintain high level of moisture for improving hydration of the cement and also provides a polymeric network which enhances toughness and durability of the finished product. Because the polymer is incorporated as an emulsion in a surfactant or "soap solutions" a high density is achieved.
