KingBond SBR400^®

Liquid polymer bonding agent for cement containing mixes.

Packaging

Drum

Overview

KingBond SBR400 is a one component styrene butadiene rubber latex bonding agent. KingBond SBR400 is designed to improve the physical properties of cement mixes and slurries.

Applications

KingBond SBR is ideally designed for use in the following Bonding of new to old concrete when used as a slurry coat
To produce polymer modified screeds and floor toppings
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
To produce waterproof renders

Advantages

Successfully increases the bonding/adhesion of cement mixes
Excellent waterproof additive which helps produce waterproof renders, screeds and toppings
Effective plasticiser giving improved workability and cohesion
Improved mechanical and physical properties by increasing tensile, flexural and adhesive strengths
Reduces shrinkage and cracking in repair and screeding mixes
Good freeze/thaw resistance
Chloride free
STANDARDS KingBond SBR400 complies with ASTM C1059-99, Type I and II, when tested in accordance with test method ASTM C1042
