Sbr-latex-rg-2062
General product information
IntroductionRG 2062 SBR Latex Bonding Admixture is a styrene butadiene copolymer latex admixture that is designed as an integral adhesive for cement bond coats, mortars and concrete to improve bond strength and chemical resistance such as resistance from abrasion, reduce shrinkage & concrete bleed, intermolecular adhesion, resistant to deicing salts.
Primary Applications consists of Toppings, Patches and leveling courses, General reconstruction work/latex modified overlays, Thin sets, Terrazzo, Stucco and bonding coats, Cement Admixture, Waterproofing and bonding strength of cement plaster as bond coat, as an Excellent water proof and weather resistant adhesive for paper & board packaging, etc.
Surface preparation and application:
Clean and wash the surface before applying as primer coat diluted to 1:2 with water and second coat with equal proportion after 4 hours interval or according to the batch size with the same *w to dry for 1 or 2 hours to develop slight tackiness and then pour compactly rich cement-concrete-sand mixture ensuring that there are no air pockets or cavities present between the old to new concrete contact areas. It is advisable to use 1.0 - 1.5 kg per bag of 50 kg cement previously mixed in the predetermined quantity of * topping must be applied to the final primer coat whilst the latter is still in wet condition. USE only portable ( drinking ) water for mixing. Note: Acid etching is not acceptable.
To achieve better results in Civil Construction it is normally used @ 1.5 kg/bag of SRC and 2.5 kg/bag of OPC previously mixed in the predetermined quantity of water, as the cement/mortar additive. In the abnormal soil / atmospheric conditions, the dosage must be increased to double the specified quantity.
