Cempatch SBR
Cempatch SBR is a one component styrene butadiene
rubber latex bonding agent. Cempatch SBR is designed
to improve the physical properties of cement mixes and
slurries.
Applications
- To produce waterproof renders.
- To produce polymer modified screeds and floor toppings.
- Bonding of new to old concrete when used as a slurry coat.
- To produce a mechanical key prior to rendering of various plaster mixes on concrete, brick and block surfaces.
- To produce a repair mortar for patching of honey- combed concrete, internally and externally.
Advantages
- Effective plasticiser giving improved workability and cohesion.
- Successfully increases the bonding/adhesion of cement mixes.
- Excellent waterproof additive which helps produce waterproof renders, screeds and toppings.
- Improved mechanical and physical properties by increasing tensile, flexural and adhesive strengths.
- Chloride free.
- Good freeze/thaw resistance.
- Reduces shrinkage and cracking in repair and screeding mixes.
- Non-toxic, can be used for concrete in contact with potable water.
