LIQUID POLYMER BONDING AGENT ADDITIVE FOR CEMENT CONTAINING MIXES.
POLYBOND SBR is a single component styrene butadiene rubber latex. It is designed to improve the physical properties of cement mixes and slurries
POLYBOND SBR is ideally designed for use in the following applications:
Bonding of new to old concrete when used as a slurry coat.
To produce polymer modiﬁed screeds and ﬂoor topping.
Bonding of thin polymer modiﬁed screeds and or toppings to old substrate.
To provide a mechanically key prior to render- ing of various plaster mixes on concrete, brick and block surfaces.
To produce a repair mortar for patching of honey cubed concrete, internally and exter- nally.
To produce water-proof renders.
Effectively increases the bonding/ adhesion of cement mixes.
Excellent water proof additives which helps produce water-proof renders, screed and toppings.
Effective plasticizer, giving improved workabil- ity and cohesion.
Improved mechanical and physical properties by increasing tensile, ﬂexural and adhesive strengths.
Reduces shrinkage and cracking in repair and screening mixes.
Good freeze / thaw resistance. Chloride free.

METHOD OF USE:
– Substrate preparation:
The substrate should be sound, clean and free from contamination. Surface laitance should be removed by acid etching.
For patch repair, cut back the edges of the repair areas tp a minimum of 10mm depth to avoid thin repair thicknesses.
All substrate should be damped with water prior to commencing the repair.
Exposed steel reinforcement should be grit blasted or wired brushed to a bright ﬁnish and protected with epoxy poly zincritch.
The recommended mix to produce slurry consistency can be achieved by mixing, by volume, 2 POLYBOND SBR 100: 3 OPC cement. Use a stiff brush to apply a thick coat to damp surfaces. Application of the subse- quent application, roughen the dry coat before applying a further coat.
All tools should be cleaned immediately after ﬁnishing with water. Hardened materials may be cleaned mechanically..
POLYBOND SBR is available in 5 litre and 200 litre drums.
POLYBOND SBR shelf life is 12 months if
stored at temperature between 5˚C and 50˚C.
If these conditions are exceeded, POLYWED technical department should be contacted for advice.
– Health and Safety:
POLYBOND SBR is non-toxic. Avoid skin and eye contact. Rubber gloves and eye protec- tions should be worn all the time. The use of barrier cream is recommended on exposed areas of the skin.
POLYBOND SBR is non ﬂammable.
