K-Fix Construction Chemicals is a retail brand from Chembond which is one of the leading manufacturers and distributors of construction chemicals in India. Various products are available under the K-Fix brand which have application at different stages of construction and repair. K-Fix products are used across segments – housing, commercial and industrial and are engineered to perform in Indian conditions. It is available for distribution channel and for professional applicators.

K-Fix provides solution for waterproofing, repair, sealing, grouting and tiling. It has high quality standardised products produced using the latest technology enabling quality construction and ease of application, without affecting any other properties.

Due to environmental and toxicology concerns and regulations, water-borne acrylic copolymers are taking over the solvent-borne binders. These systems have now become a popular choice of waterproofing material, due to their advantages in application and storage.

Acrylic co-polymers are aqueous emulsion based polymers, which are used as a binder to “bind” pigments, extenders and special fillers together. These are made by polymerising acrylic monomers, forming long-chain polymers, with high molecular weights. The acrylic co-polymer emulsions used in waterproofing coating have good UV and weathering resistance, flexibility, breathability, and water proofing properties. Coating thickness and uniformity plays a critical role in achieving final film properties. Elastomeric properties are highly influenced by the thickness of the coating.

KEM PROOF 86
KEM PROOF 86 is high quality acrylic emulsion based coating. It is elastomeric in nature and good resistance to weather and sunlight.

Features
• Capable of resisting movements in structures and has good crack bridging and water proofing    properties due to its good film thickness
• Excellent elasticity (<100 per cent at 100 – 125 microns DFT). At the same time, it is tough enough to withstand heavy rains
• Has longer service life due to excellent UV resistance
• Good resistance to fungus and algal growth
• Good breathability and permeability to water vapour
• Non-toxic coating
• Low dirt pick up due to low tack-free time
• Ready to use and easy to apply using brush roller and spray
• Ensures desired thickness as there is no need for additional water for dilution.

Areas of application
As waterproofing and protective coating for exterior walls of buildings. Typical substrate includes masonry, concrete; cement and waste plaster as well as cement boards.

Standards
KEM PROOF 86 complies to ASTM C 1202 – 97, BS EN 12390, ASTM D 412 – 02, ASTM C 836:1995

Coverage
3 – 4.5 sq. m. per litre for two coats. However, coverage may vary depending upon the texture, porosity and condition of the surface.
Packaging
5 litres and 20 litres.

KEM PROOF 87
KEM PROOF 87 is an elastomeric coating based on selected acrylic co-polymers. When applied, it cures to form a durable, protective, waterproof membrane. It is applied by brush or roller. It can be applied on concrete, cement board, wood, brick, stone and tiles. It is a single-component emulsion containing inert pigments and has a brushable consistency.

Features
• Good resistance to UV and atmospheric gases and salts ensures excellent durability
• Good tensile strength and elongation ensures crack bridging and movement accommodation
• Highly resistant to water.

Standards
KEM PROOF 87 complies ASTM D 2240:2002, ASTM E 96:2000, ASTM D 412-02, ASTM C 1202-97, ASTM C 836:1995, BS EN 12390 Part 8:2000.

Areas of application
• Used for coating roofs, it protects concrete structures against carbonation and chloride ingress
• Typical surfaces include concrete, cement good, woods, bricks, tiles
• It can also be used in damp and sunken areas such as under terrazzo or tile floors, shower pans, kitchen, laundry and bathroom floors.

Coverage
2 – 2.5 sq. m. per litre. Coverage may vary depending upon the texture, porosity and condition of the surface.

Packaging
5 litres and 20 litres.
